Posted by: ohapuqa - 10-29-2018, 06:39 AM - Forum: aluminium faq - No Replies Aluminum 1100 is among the softest aluminum alloys and therefore is not used for high-strength or high-pressure applications. Though it is often cold-worked, pure aluminum can be hot-worked as well, but more frequently, aluminum is shaped by spinning, stamping and drawing processes, none of which require the use of high heat. These processes produce aluminum shapes in the form of foil,plates, round bars or rods, sheets, strips, and wire. Aluminum 1100 can also be welded; resistance welding is possible, but it can be difficult and usually requires the attention of skilled welders. Aluminum 1100 is just one of several common aluminum alloys and is soft, low strength and, at 99% min aluminum, is the commercially pure aluminum. Copper, iron, magnesium, manganese, silicon, titanium, vanadium and zinc comprise the remaining elements. It cannot be hardened by heat treatment and is very formable. Cold-working is the most common way to form aluminum 1100. A cold metalworking process is any metal shaping or forming process that takes place at or near room temperature. aluminum sheet 1100 H14 can be shaped into many different products, including chemical equipment, railroad tank cars, fin stock, dials, name plates, cooking utensils, rivets, reflectors and sheet metal. The plumbing and lighting industries also use aluminum 1100, as do a wide variety of other industries. Performance advantage: 1, aluminum sheet 1100 H14 with high corrosion resistance, electrical conductivity and thermal conductivity, its density is small, good plasticity, through pressure processing can produce a variety of aluminum; 2, aluminum sheet 1100 H14 has low strength, but with good ductility, formability and weldability; 3, the anode oxidation can further improve the corrosion resistance, while obtaining a beautiful surface; The company Haomei Industrial Co., Ltd. China’s largest aluminum sheet 1100 H14 manufacturers and suppliers, the production of 1-8 series aluminum alloy plates to provide you with the best price and high quality services   Does newspapers work as a better insulator than aluminum foil? Posted by: Tyeshacon - 10-29-2018, 06:27 AM - Forum: aluminium faq - Replies (1) Adding insulation to your home is an easy way to save on energy costs. Aluminum foil, also called tin foil, makes an excellent insulator, and in some situations, it works better than materials like cotton or newspapers. Aluminum foil is not best for every situation, though, so using it correctly is an important part of saving energy. Simply sheets of pliable aluminum that are less than 0.2 mm thick, aluminum foil has several household uses. Some companies manufacture long, stronger strips specifically for insulation, but you can also use typical aluminum foil to insulate. If the foil is particularly thin, companies will sometimes laminate it with plastic, paper or other materials to make it stronger. [img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/02/aluminiumfoilstrip-300x300.jpg[/img] Benefits Because aluminum foil reflects light, it can be used for insulation, especially in areas that need to be guarded against heat. When it is used with other materials, it can be used to warm an area, too. Other materials such as paper and cotton, do not have the reflectivity that aluminum foil does, so when the sun is bearing down, they will not keep it out as well. An area that is already hot will be kept hot by aluminum foil, as it will hold in hot air. Paper and cotton will release heat at a quicker rate than aluminum foil. Aluminum foil can keep things like wires or pipes insulated, as it traps air when it is wrapped around an object. This can be achieved with several objects, though, and not just aluminum foil. Using Aluminum Foil Insulating a room in the summertime with aluminum foil can help keep sunlight out of the room and lower temperatures. Completely cover all windows with aluminum foil and secure it with a heavy-duty tape such as duct tape. The shiny surface will reflect the sunlight’s rays. You can also insulate cold food when it will be near the sun. Wrapping a cold soda can, for instance, with aluminum foil will keep it chilled. Adding a layer of bubble paper between the aluminum foil and soda can will keep it cooler for longer. Considerations If you would like to insulate something in a dark place, such as lunch box, another material such as cotton or paper could work just as well as aluminum foil. As a matter of fact, cotton is regularly used for insulation, as it is environmentally friendly. Because aluminum foil reflects light, when it is in a dark place, there is no light for it to reflect, so it will work similarly to other materials   Four ways to easily handle the difference between cold rolled aluminum and hot rolled Posted by: ohapuqa - 10-26-2018, 07:03 AM - Forum: Knowledge & Technique - No Replies cold rolled aluminum and hot rolled aluminum In the process of aluminum plate procurement, different requirements have different requirements on the type, material and process of aluminum plate, especially the distinction and recognition between cold rolled aluminum plate and hot rolled aluminum plate, which plays an important role. Aluminum plate industry, aluminum plate classification, according to the production process, aluminum plate can be divided into cold rolled aluminum plate and hot rolled aluminum plate. The difference between cold rolled aluminum sheet and hot rolled aluminum sheet is as follows: [img=224x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/03/aluminum_plate-15-224x300.jpg[/img]aluminum plate Method 1: the production process is different: the cold rolling is made by casting and tying machine (8mm thickness), which is processed by cold rolling machine. The hot rolling is made by heating aluminum ingots (400-500mm thickness), which is rolled by hot rolling mill at high temperature. Method 2: the supply of raw materials is different: the two are different in the supply of blank. The hot-rolled blank is cast aluminum ingots — heated — rolled into rolls for cold rolling. Method 3: different properties: hot rolled aluminum plates have good surface quality, strong mechanical properties and ductility, and good oxidation effect. Aluminum wafers processed at the same time are generally processed by aluminum plates, and naturally affected by the performance of aluminum plates. Method 4: different USES: cold rolled aluminum plate is mainly used in the mold, hot rolled aluminum plate is suitable for stamping and stretching aspects. Through the above four methods, we can easily distinguish the cold rolled aluminum sheet from hot rolled aluminum sheet. The choice of aluminum sheet requires professional knowledge, and the purchase of aluminum sheet requires more professional manufacturers. If you are interested in our aluminum sheet products, we sincerely look forward to your presence and visit.   How to tell the difference between 2A12 and 6061 aluminum plates Posted by: Tyeshacon - 10-26-2018, 06:40 AM - Forum: aluminium faq - No Replies aluminum alloy 2A12 and 6061 both belong to heat-treatable aluminum alloy, and they are difficult to distinguish from each other in appearance after heat treatment. Because of the huge difference in price between them, the difference is probably over 10000 yuan/ton. Therefore, many dealers in the market use 6061 aluminum plates to pretend to sell 2A12 aluminum plates. How to tell the difference between 2A12 and 6061 aluminum plates Hardness: after heat treatment, the hardness of 6061 aluminum plates is at 90HB, while 2A12 aluminum plates can reach around 120HB. The hardness difference between the two is large. If you have the brightness measuring equipment, the hardness can be measured. 2. Density: if you do not have a hardness tester, there is a simple method. The density of 6061 aluminum plates can only reach 2.7. Weight formula: thickness (mm) * density (2.7/2.78) * length (m) * width (m) = weight See which end product is closer in weight, so you can tell the difference Third, if in doubt, it can be detected by the third party. The content of each alloy element can be determined by the elemental analysis instrument and then the national standard alloy content can be obtained.   Mirror aluminum sheet polishing process Posted by: Tyeshacon - 10-25-2018, 08:28 AM - Forum: Knowledge & Technique - No Replies Mirror aluminum refrigerator copper aluminum tube welding video 5083 aluminum pipe fittings veneer with mirror effect is popular, is widely used in lighting lamps and lanterns reflective panels and decorative lamps and lanterns, solar reflective materials, interior decoration, integration ceiling, wall decoration, household electrical appliance panels, electronic products shell, kitchen furniture, car inside and outside decoration, signs, logo, cases, bags, jewelry box, etc. Here today to share making a polished mirror aluminum sheet process. Mirror polishing technology of aluminum sheet: in addition to the oil – water – polishing – water – washing, profile after oil removal in the polishing groove, namely by 2 to 5 minutes after polishing, can form a mirror, after wash can be directly oxidized. The core of the technological process is polished, to grain, the mirror is done in polishing groove. Polishing possesses the advantages of aluminum consumption is low, profile light. But produce nitrous oxide polishing process of escape, cause serious pollution of the environment and the operators of bodily injury, at the same time, the expensive chemical raw material costs and other factors but also restrain the process of the promotion. Our company through the hot copper mirror technology, specular reflectance can reach more than 86%, and can be used in the anode Oxidation treatment. Rolling of mirror aluminum solves the problems of low efficiency of polishing mirror aluminum in China, residual polishing wax traces on the surface, unstable mirror effect and so on, and greatly reduces the cost and meets the environmental requirements, directly benefiting customers.   How to distinguish between polished aluminum mirror sheet and mirror finish anodized Posted by: ohapuqa - 10-25-2018, 07:58 AM - Forum: aluminium faq - Replies (1) How to distinguish between polished aluminum mirror sheet and  mirror finish anodized aluminum sheet?  The person that is familiar with aluminum mirror sheet knows, this material has at present domestic, also have abroad, what homebred and imports is to have not little difference. The imported products are usually treated with anodization, while the domestic surface is usually treated with simple polishing instead of this process. The process is different, the performance is different, the price difference is also very big. After the anodization performance is stronger, not easy to be damaged, produced a higher level of products. How to distinguish between polished aluminum mirror sheet and mirror finish anodized aluminum sheet? Many methods, such as tear protective film on the surface of the can, and then touch the mirror, see the perspiration will stay above, and then clean the paper, look at that, if left no trace, is after anodic oxidation treatment, and if not only left hand finger print, and the clean the dirty of that kind of is the mirror polishing. Another approach is to bend the aluminum around the ear and listen for specific sounds that, if slightly broken, are anodized, whereas polished ones do not. Another method is to bend the product at 90 degrees T. The product with good quality will have slight bleaching. When the anodized film is burst, it will have bleaching, while the product with poor quality will not have such condition. These three methods are relatively easy to distinguish between anodized mirror aluminum sheet and polished aluminum mirror sheet. Specific when carrying on a selection, need to identify carefully, careful those illegal peddler with shoddy, affected his later use.   Attention should be paid to aluminum oxidation treatment Posted by: Tyeshacon - 10-24-2018, 08:21 AM - Forum: Knowledge & Technique - No Replies In order to create a hard surface on the aluminum surface, some aluminum workpieces will be oxidized to process. In this way, the process effect can not only improve the performance of aluminum workpieces, but also improve the appearance of workpieces. However, some matters need to be paid attention to after the aluminum oxidation treatment, otherwise the use effect of aluminum workpiece is not good, and even lead to the early damage of aluminum. Rinse with hot water The purpose is to age the film layer, but the water temperature and time should be strictly controlled. Processing time is too long also can appear the similar problems, appropriate temperature and time is: temperature of 40 ~ 50 ℃ 0.5 ~ 1 minutes. Second, the dry It is better to dry by natural air, and the workpiece washed with hot water is slanted on the shelf, so that the free water on the working surface is straight down to the bottom. The water that flows to the corner edge of lower end USES towel to absorb, the film layer color that is dried by this method is not affected, appear natural. Three, aging Aging method according to climate condition to decide, there are in the summer the sun exposure in the sun, the aluminum oxide rainy or winter available oven roasted, process condition is: temperature of 40 ~ 50 ℃ 10 ~ 15 minutes. Repair of unqualified parts The unqualified conductive oxide film should be selected before drying and aging process. After drying and aging, the film layer is difficult to be removed and will affect the roughness of workpiece surface. For the unqualified workpieces, we can take the following simple measures to solve. First, the unqualified workpiece is clamped on the clamping device for aluminum anodization. Then, the anodization process of aluminum in sulfuric acid solution is performed for 2~3min. After the film layer is soft and peeling, the conductive anodization can be re-conducted after the alkali solution is cleaned and the nitric acid is exposed to light. Aluminum oxide pendulum cesium art requirements artifacts into heat treatment or subject to organic solvent cleaning before welding process, free surface oil, but now can't do it, so form a layer of oil on sintering of coking on the surface of workpiece, this layer of coking content in organic solvents is difficult to remove all, if soaked in lye can cause local corrosion, pitting or cause uneven, seriously affecting the quality of the product.   Common quality defects and causes of aluminum sheet coil Posted by: Tyeshacon - 10-24-2018, 08:17 AM - Forum: Knowledge & Technique - No Replies Common quality defects and causes of aluminum sheet coil 1.
