The pattern aluminum sheet is a high cost modern material. There are many kinds of materials. It is widely used in furniture, such as refrigerator, air conditioner, carriage, platform, packing pipe, screen frame, all kinds of hanging beams, table feet, decorative strips, drawing hand, walking groove and cover, chair pipe and so on.
![[Image: aluminumdiamondplate.jpg]](http://thick-aluminum-plate.com/images/aluminumdiamondplate.jpg)
Using a pair of steel rolls, the pattern is carved on the steel roll, the section of the section two steel rolls center distance and the steel roll rotation, the flat aluminum plate is passed between two steel rolls, and the pattern is imprinted on the aluminum plate. This is just one technology, and there are many other differences. We need to specify the processing technology accordng to the pattern. Like the big five ribs, the reverse side should be flat since it is pressed.

Advantages of copper clad aluminum wire:
1. Dc resistivity: the dc resistivity of the copper clad aluminum wire is about 1.5 times that of the pure copper wire, and the copper clad aluminum wire is about 1/2 the weight of the pure copper wire. According to the "skin effect" calculation, the resistivity is the same as the pure copper wire at the high frequency of 5MHZ.
2. Good weldability: copper clad aluminum wire has the same solderability as pure copper wire due to its concentric coating of pure copper.
3. Light weight: the proportion of copper clad aluminum wire is only 37% - 37% of pure copper wire, online diameter, under the condition of equal weight, the length is 2.5 times of pure copper wire, thus greatly reduces the production cost, buy 1 ton of copper clad aluminum wire is bought 2.5 tons of pure copper wire;
4. Copper clad aluminum wire has obvious advantages over pure copper wire: light weight, convenient transportation, soft and easy to process, saving copper resource consumption and low cost. The cost comparison between the copper clad aluminum wire and the pure copper wire:
The density of copper clad aluminum is 3.63g/cm3, the copper density is 8.89g/cm3, and the density ratio is 1:2.5, so the length of 1000kg copper clad aluminum magnesium alloy wire is equivalent to the length of the pure copper wire of 2500kg.
For example, the copper clad aluminum wire has a price of 72 yuan /kg. Pure copper bare wire is sold for 48.6 yuan /kg.
The cost of saving is about 48600 yuan (48600 yuan * 2.5 times - 72,000 yuan =48600 yuan) using 1000kg of copper clad aluminum wire and 2500kg pure copper wire.
Therefore, the use of copper clad aluminum wire instead of pure copper wire can greatly reduce the cost of raw materials.

Aluminum alloy is the most widely used nonferrous metal structure material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welding structure is increasing, and the welding research of aluminum alloy is also deepened. Aluminum alloy is widely used to promote the development of aluminum alloy welding technology, at the same time, the development of welding technology and expand the application field of aluminum alloy, thus the welding technology of aluminum alloy is becoming one of the hot spot of research. Aluminum alloy: aluminium based alloy general term. The main alloy elements are copper, silicon, magnesium, zinc and manganese, and the secondary alloy elements are nickel, iron, titanium, chromium, lithium, etc.
The density of pure aluminum (rho = 2.7 g/cm3), is about 1/3 of the iron, low melting point (660 ℃), aluminum is face-centered cubic structure, therefore, has the very high plasticity (delta: 32 ~ 40%, and bits of: 70 ~ 90%), easy to machining, can be made into various molding, plate. Good corrosion resistance; However, the strength of pure aluminum is very low, and the value of the annealing state is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practices and scientific experiments, people gradually strengthened aluminum by adding alloy elements and using heat treatment methods, which resulted in a series of aluminum alloys. In addition, the alloy with certain elements can have high strength while maintaining the advantages of pure aluminum, and the value of b can be up to 24 ~ 60kgf/mm2 respectively. So that its "strength" (the ratio of intensity and the proportion of sigma b/rho) is better than a lot of alloy steel, become the ideal structural material, widely used in machinery manufacturing, transportation, machinery and aviation industry, the aircraft fuselage, skin, such as compressor with aluminum alloy manufacture, in order to reduce weight. Using aluminum alloy instead of steel plate material welding, the structure weight can be reduced by more than 50%.
Aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used on industry, usage is second only to the steel.
The billboard of general outdoor USES aluminium alloy board is good.

Aluminum is a metal substance, which is not a trace element needed by the human body, and the amount of aluminum in food that exceeds the national standard can be harmful to human health.
If excessive consumption of aluminum or aluminum excessive amounts of food consumption, affect the normal metabolism of human body cell, affect a series of biochemical reactions, can cause memory loss, cause the problem of dementia in the elderly. As for children, in the process of growth and intellectual development, excessive consumption of aluminum can seriously affect the intellectual development of children.
In foods with excessive aluminum consumption, aluminum can accumulate in the body continuously, causing pathological changes in the nervous system, interfering with people's thinking, consciousness and memory function, and may lead to dementia. Excessive intake of aluminum may also cause calcium loss in bone, inhibit bone formation, and osteomalacia.
Once the aluminum salts enter the human body, they are first deposited in the brain, which can cause brain damage and cause severe memory loss, which is a characteristic of alzheimer's disease. The researchers, who were involved in the work, said experiments with mice showed that the amount of aluminum in their brains reached measurable levels after just drinking a glass of water treated with aluminum salts. A study of rats found that trace amounts of aluminum mixed in drinking water entered the brain and gradually accumulated there. Researchers study of dementia patients, found that these patients, 30% new brain cortex in aluminum concentrations greater than 4 micrograms per gram (dry weight), patients with brain neurons within the nucleus, the aluminum content is four times that of healthy people, the largest up to 30 times. The researchers believe that, over time, aluminum accumulates in the brain, killing neurons and causing memory loss. 'we've spent our lives drinking aluminum salts and eating foods that contain aluminum,' says one scientist. 'so when we're old, we've built up a lot of aluminum.' He points out that the incidence of alzheimer's disease has risen worldwide in the past 70 years. Aluminum is also used in food emulsifiers, he said.
Aluminum can directly damage the activity of osteoblasts, thereby inhibiting the matrix synthesis of bone. At the same time, the absorption of aluminum by the digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium in the human body. Aluminum accumulates and performs physiological functions in the human body, which can also cause encephalopathy, bone disease, kidney disease and non-iron deficiency anemia.
To prevent the harm of aluminium article there are three main ways: one is the recommended city tap water company in line with the aim of responsible to the people to oneself, do not use aluminum salt [such as potassium aluminium sulfate (KAI (SO4) 2) water purifier; 2 it is as far as possible need not aluminum cooker; 3 it is to eat less food containing aluminium salt additives is more (e.g., Fried dough sticks).
Aluminum is very toxic to human body, and it is toxic to biology. Soluble aluminum compounds are toxic to most plants, and the dissolved aluminum compounds in the water of acidic soil make it difficult for normal crops to grow properly. Usually when the dissolved aluminum reaches 10 to 20PPM, the plant will have an aluminum toxicity. The aluminum in the soil can be combined with soluble phosphate to produce insoluble phosphoric acid, which causes the plant to die without phosphorus. Aluminum also dehydrates plant cells and destroys them. The combination of aluminum and pectin in the cell wall strengthens the crosslinking structure of pectin, which hinders the absorption of water and nutrients. The mineral nutrients such as calcium and phosphorus in plants are closely related. It can inhibit the absorption and accumulation of calcium and phosphorus in general plants, and also affect their absorption and accumulation of elements such as potassium, magnesium, manganese, copper and zinc. Aluminum to aquatic animals also have poison, when pH is about 5, deposition in aluminum hydroxide form within the gills, made it difficult to make oxygen into the blood, fish salt concentration in the body and the imbalance, causes the death of fish. The toxicity of aluminum to aquatic animals is generally 70 micrograms per liter. The increase of aluminum content in the water will result in a large amount of organic matter coagulation, which will cause aquatic animals to die due to lack of nutrition. Aluminium can precipitate phosphorus and seriously threaten the reproduction of aquatic animals.

One reason:
In ancient times, the production technology of aluminum was very backward, so the working time of aluminum was longer than that of silver, so aluminum was more expensive than silver in the market.
Two. Analysis:
At that time, the refining technology of aluminum metal was not good, the price of aluminum was more expensive than silver, so people used to use aluminum products as the honor to show their status. Napoleon, the French emperor, is a man who likes to show off. He often banquets and banquets all the guests. He always puts on a superior look at every party. Almost all the utensils on the table were made of silver, and the only bowl he used was aluminum products.
It turned out that in the Napoleon era almost 200 years ago, smelting and using gold and silver had a long history. However, at that time, people just learned that aluminum can be smelted from bauxite, and the technology of smelting aluminum is still very backward. Smelting aluminum is very difficult.
Therefore, aluminum was very rare at that time. Not to mention the fact that the common people could not afford it. Napoleon asked guests to use silver tableware, just to use their own aluminum bowls, just to show their dignity and dignity.
It must be ridiculous to get it now, because today, aluminum is much cheaper than silver, and its luster and performance are far less than silver. Aluminum became cheaper because people later invented the technology of electrolytic aluminum, which can produce aluminum in large quantities. The main raw material of aluminum smelting is the earth's large reserves of bauxite. The production technology of aluminum, which is rich in raw materials, enough in electricity and efficient, has made the output of aluminum rise rapidly, and aluminum has become a very common thing.

Here I just talk about the harm of aluminum to the human body.
Aluminum is not an essential element of the human body. When the body lacks aluminum, it will not cause any damage to the human body. On the contrary, aluminum salt can cause human poisoning. As early as 1965, Kako first discovered the brain of aluminum poisoning in the rabbit, and there was an endemic neurofibrillary tangled disease of Alzheimer's disease. It was not until 1973 that he pointed out that the increase in the amount of aluminum in the cerebral cortex of the cat showed that the cat had obvious brain dysfunction, which was to wake the world.
Aluminum is toxic to organisms, especially to humans. Soluble aluminum compounds are toxic to most plants. The dissolved aluminum compounds in the acidic soil make it difficult for ordinary crops to grow normally. Usually when the dissolved aluminum reaches 10-20PPM or more, plants will have aluminum toxic symptoms. In the soil and soluble phosphate aluminum can combine to form insoluble aluminum phosphate, induced by phosphorus deficiency and zhe dead plants. Aluminum also dehydrated the protoplasm of plant cells, then destroyed and died. The combination of aluminum and pectin in the cell wall strengthens the cross-linking structure of pectin and hinders the absorption of water and nutrition by plants. Aluminum is also closely related to mineral nutrients such as calcium and phosphorus in plants. It can inhibit the absorption and accumulation of calcium and phosphorus by common plants, and also affect their absorption and accumulation of elements such as potassium, magnesium, iron, manganese, copper and zinc. Aluminum is also toxic to aquatic animals. When the pH value is about 5, it is deposited in the gills by aluminum hydroxide, which makes oxygen difficult to enter the blood, and makes the fish incompatible with salt, causing the fish to die. The toxicity level of aluminum to aquatic animals is generally 70 micrograms / liter. The increase of aluminum content in water will lead to the aggregation of large amounts of organic matter and the death of aquatic animals due to lack of nutrients. Aluminum can precipitate phosphorus and seriously threaten the reproduction of aquatic animals.
Once the aluminum salt enters the human body, it is first deposited in the brain, which may cause brain damage and cause serious memory loss, which is a characteristic symptom of Alzheimer's disease. The researchers who were involved in the work said experiments on mice showed that the content of aluminum in their brains reached measurable levels after drinking only a cup of water treated with aluminum salts. Studies on rats have found that trace aluminum mixed into drinking water enters rat brain and accumulates gradually. The researchers' study of dementia patients found that the concentration of aluminum in the 30% neocortex areas of these patients was more than 4 micrograms per gram (dry weight), and the content of aluminum in the nucleus of the brain neurons was 4 times as large as that of the healthy people, up to 30 times as large as that of the healthy people. Researchers believe that if aluminum accumulate in the brain over time, it will kill neurons and cause memory loss. One scientist said: we've been drinking aluminum salt water and eating aluminum - containing food all my life, so we have accumulated a lot of aluminum by the time we are very old. He pointed out that the incidence of Alzheimer's disease has increased worldwide over the past 70 years. He says that aluminum is also used in food emulsifiers.
Aluminum can directly damage the activity of osteoblasts, thus inhibiting bone matrix synthesis. At the same time, the absorption of aluminum by digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium content in human body. Aluminum accumulates and acts physiologically in the human body, and it can also lead to encephalopathy, osteopathy, nephropathy and non iron deficiency anemia.
There are three main ways to prevent the harm of aluminum: first, it is suggested that the city water company should not use aluminum salt [KAI (SO4) 2) as a water purifying agent in accordance with the purpose of its own responsibility to the people; two is to use aluminum as a cooking utensil as far as possible; three is to eat less food containing aluminum salt additives (such as oil strips).
So how do we prevent a lot of intrusion of aluminum in everyday life?
An aluminum cooker is used correctly. Because the aluminum cooker, soft and soft, easy to scrape, and can be slow chemical reaction with sugar, salt, acid, alkali, wine and other chemical reactions and overflow more aluminum, thus increasing the opportunity for people to eat aluminum. Therefore, it is not too long to use aluminum cooking utensils to store salt, acid and alkali foods. Do not use aluminum spades, aluminum spoon and other appliances, because they are in the long scraping of stir fry and rice, produce the invisible aluminum chips, which can enter the body with the food entrance. The application of bamboo spoon or non-toxic plastic spoon rice. It is recommended that families with conditioned conditions do not use aluminum cooking utensils, except that they can use stainless steel cooking utensils besides iron pots and casseroles. Because stainless steel products are stable in metal properties and harmless to human body.
No food containing more aluminum. Eat or not eat the use of aluminum containing food additives made of cakes, pastries, bread and biscuit Deep-Fried Dough Sticks, food etc.. Take the fried dough sticks as an example, each oil treaty contains aluminum 10mg, eating two two a day, taking aluminum 600mg a month, which is 10 times of the normal human body's aluminum content. The content of aluminum in tap water is very low, in line with national health and safety standards, can be assured to drink.
Eat healthy food and do fitness activities. On the one hand, we can eat more walnut kernel, sesame, green bean and other brain foods. On the other hand, in order to prevent Alzheimer's disease, we should strengthen the exercise of brain and brain, look at books and newspapers, think more, play chess, talk to people, participate in sports activities suitable for the elderly and so on.
Some substances are contained in the human body, but these substances do not have any effect on the human body. On the contrary, these substances will be harmful to the human body when the content of these substances is high in the human body. Because aluminum products are widely used in life and aluminum salt is widely used to purify water, the aluminum content in the human body is relatively high.

Although many people know that aluminum is harmful to the human body, the reason for the damage to the human body is not very clear, so so far aluminum products still occupy an important position in the family life.
Aluminum, in the environment of human life, especially in the plants growing in acid soil, is very high in content, and in addition to its extensive industrial and living uses, it is very closely related to people's life.
In recent years, researchers have found that aluminum can significantly reduce the content of norepinephrine, dopamine and 5 hydroxytryptamine in the brain and block the neurotransmitter conduction, resulting in a decline in the learning and memory ability. This conclusion has made a scientific explanation for Alzheimer's disease and mental retardation caused by aluminum. At the same time, they found that the combination of aluminum and citric acid can promote the absorption of aluminum by the gastrointestinal tract and easily enter the brain tissue through the blood brain barrier, which interferes with the conduction and normal metabolism of the nerve, and can accumulate in the bone tissue and make the bone decalcified.
The study also revealed that, regardless of the dose, the activity of the enzyme in the hepatocytes and the renal proximal convoluted tubules was denatured, resulting in a decrease in the activity of succinic dehydrogenase and ATPase, which was important to the metabolism, and thus seriously interfered with the cycle of the three carboxylic acid. Ultrastructural observation also confirmed that the mitochondria appeared ruptured, dissolved and collapsed in mitochondria of hepatocytes and kidneys. This indicates that aluminum has the most significant effect on the liver and kidney. In addition, aluminum can also affect the normal metabolism of myocardium and cause structural damage.
Another important finding of researchers is the adverse effects of aluminum on immune function. The experiment shows that aluminum can obviously reduce the transformation ability of T lymphocyte and inhibit the function of antibody forming cells and macrophages, which leads to the decrease of immune ability and the increase of susceptibility to disease. Because the accumulation of aluminum in the body is long-term, although there is little obvious toxic symptoms in the short term, with the increase of the volume of aluminum accumulation in the body, it will eventually lead to symptoms related to brain, heart, liver and kidney function damage.
So the researchers suggest: try not to use aluminum cooking utensils and tableware as much as possible, especially if the aluminum containers can not be stored for a long time, because the acid in the food can dissolve a large amount of aluminum, and then make the human body eat too much, and prevent the milk from being cooked in the aluminum pot so that children should be injured in the young hours; when making pasta, the active dry fermentation should be used. Mother powder is used as a starter to avoid using chemical ferment powder containing ammonium aluminum sulfate and aluminum potassium sulfate, and iron or enamel cooking utensils and tableware are often used.
It is appropriate to use iron or stainless steel pot, if the spatula is aluminum, the softer aluminum shovel will be worn by stainless steel pot or iron pan into powder particles, thus entering the body with the food. On the contrary, if aluminum shovel and shovel or stainless steel shovel are used, the aluminum in the aluminum pot will easily be worn away by the shovel of shovel or stainless steel shovel into the human body. It takes only two or three years, aluminum or aluminum pot shovel will wear off, make aluminum body soared many times. Cooking using aluminum pot, it is best to use plastic or wooden spoon.
