How do we smelt aluminum in ancient times? Posted by: aluhm - 04-09-2018, 02:28 AM - Forum: aluminium faq - No Replies In ancient times, it could not electrolysis, but there was still a little aluminum. Legend has it that Napoleon and his knives and forks are made of aluminum. At the banquet, he provided gold tableware for most guests, and only a few guests used aluminum tableware to make a deeper impression on the guests. In 1885, the top hat of Washington Monument, built in Washington, D.C., was also made of metallic aluminum. Because in the nineteenth Century, aluminum was a precious metal. The aluminum grain that people first acquired is just like a treasure, and its price is equal to that of gold. Because it is extremely difficult to extract aluminum from aluminum ores. In 1825, a small amount of pure aluminum was separated from the OE of Denmark. In 1827, hler metal potassium and anhydrous aluminum chloride reaction and prepared aluminum. But K is too expensive, so do not allow a large scale production. 27 years later, a French chemist, Deweier, heated with metallic sodium and anhydrous aluminum chloride to get a small aluminum ball that shone with metallic luster. Although the use of metal sodium greatly reduced the production cost of aluminum, it obviously did not reach the level of universal application of aluminum. In 1884, the United States Department of chemistry at Oberlin College, a young student named Charles Martin Hall. He was only twenty-one years old. Once, he listened to a professor (this professor is a student of Weller), said: "no matter who can invent a low-cost aluminum smelting method, it will get ahead." This made Holzer realize that only by exploring cheap aluminum smelting method can aluminum be widely applied. Holzer decided to run a family laboratory in his home's firewood house. He intends to apply an early David invention to melt the current into molten metal salts that can deposit metal ions on the cathode to separate the metal ions. Because the melting point of alumina was very high (2050 degrees C), he had to look for a material that could dissolve alumina and reduce its melting point, and accidentally found the Na3AlF6. The melting point of cryolite alumina molten salt is only between 930 and 1000 degrees. Cryolite is not decomposed under the electrolysis temperature and has enough fluidity. This will be beneficial to the development of electrolysis. Holzer adopts porcelain crucible, carbon (anode) and self-made batteries of alumina, Alumina ore is refined by electrolysis. The alumina was dissolved in 10% ~ 15% melted ice crystals, and then passed through the current. It was observed that bubbles appeared, but there was no metal aluminum precipitation. He speculated that the current dissolved the silica in the crucible, and therefore free silicon. So he refitted the battery, made carbon as the crucible liner, and used carbon as the cathode to solve this problem. One day in February 1886, he finally saw that globular aluminum gathered on the cathode. Holzer was very excited at the moment and went to see his professor with the first metal ball he got. Later, the aluminum ball has become a "crown jewel", Jane still exist in the United States aluminum company exhibition hall. The invention of the cheap aluminum smelting method made the aluminum content in the earth's crust account for 8% of the total elements, and has since become a material that provides many important uses for mankind. Inventor Holzer, who was 23 years old, was his 23 birthday in December 6th. There was another thing to mention. It was a great coincidence that a young French chemist of the same age with Holzer, ALU, invented the same process of aluminum smelting later this year. Holzer and Herou in the distant two continents, the same year came into the world (1863) and the same year the invention of electrolytic aluminum RefiningTechnology (1886). Although they once had a patent dispute, but later became friends with complete mutual understanding. In 1911, when the American Chemical Industry Association awarded Holzer the famous prizes, Lu also went to the United States to take part in the award ceremony, and congratulated Holzer himself. Maybe it was heaven's decree. In 1914, all two scientists died one after another. I wonder when people mention electrolytic aluminium production method, then to Holzer and Herou names together.   What's the difference between raw aluminum and cooked aluminum? Posted by: aluhm - 04-09-2018, 02:26 AM - Forum: aluminium faq - Replies (2) 1. hard aluminum alloy which is aluminum and copper, magnesium, manganese and so on. This kind of aluminum alloy is suitable for pressing rolling. The strength and hardness of the products are much larger than that of the ordinary aluminum products. They are much more. 2. raw aluminum than ordinary aluminum products: many impurities, very brittle, and a knockout. The raw aluminum is often recycled aluminum, it is the.3. ripe aluminum which is reused by the broken aluminum pot and the broken aluminum spoon. The content of aluminum is about about the content of aluminum 98%, impurities (mainly iron and silicon) about 2% or slightly more j are relatively pure aluminum. It is soft and can be crushed into a variety of shapes. The daily aluminum pan, aluminum lunch box, aluminum sheet, aluminum wire and aluminum tube are all cooked aluminum. The difference between them can be clearly seen from the definition.   PP Cap Materials-aluminum sheet and coils Posted by: mepehuxit - 04-08-2018, 08:56 AM - Forum: Buying Leads - No Replies Haomei supplies aluminum sheet and coils for the manufacture of bottle closures.

As a matter of fact, some other applications remain unmentioned. Aluminum sheet coil, if mixed with other materials like plastics, becomes perfect packaging material for liquid food. Take sterility packs for milk as an example. These packs are made of aluminum sheet coil and plastic film of high strength and heat-sealing property. They are so strong that people can not tear it by bare hands. If you want to turn a milk carton into a flat piece of sheet, you have to use scissors. Aluminum sheet coil, as a bulk commodity, is familiar to everybody. Speaking of its application, many people would give answers like building decoration, kitchen cupboards, automobiles, ships and vessels, planes, advertising boards and even bottle caps, but few people connect aluminum sheet coil with food. [img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/02/aluminiumfoilstrip-300x300.jpg[/img] Once pressed thin enough, aluminum sheet coil becomes protective angels for popular children food–sweets. The thin layer of film around sweets protect them against moisture and harmful bacteria. And the happiness of tearing the film apart still haunts many adults whose childhood was so simple that a piece of sweet could remove all sadness. Another application of aluminum sheet coil for food packaging proves to be very popular–meat packaging. Exquisite delicatessens wrap cooked beef or chicken with bright aluminum sheet coil before putting it into a plastic box or bag. At home, people also cover food with packaging aluminum before cooking it with a microwave oven. This keeps the food being cooked evenly and from getting burned. If you go for a barbecue, you can wrap different foods using packaging aluminum and cook them directly later.   Industrial Pure Aluminum Coil Stock Posted by: mepehuxit - 04-08-2018, 08:32 AM - Forum: Knowledge & Technique - No Replies Industrial pure aluminum coil stock, also called 1xxx coil stock, refers toaluminum coil in which the content of aluminum reaches 99% or above. Different number types stands for different content of aluminum in the coil. For example, 1050 means there is 99.5% aluminum element in the coil, and 1060 99.6% aluminum in the coil. The commonly used types are 1050, 1060, 1070, 1100 and 1200. industrial pure aluminum coil stock Industrial pure aluminum coil stock has many advantages. First, it boasts small density. The density of pure aluminum reaches as low as 2700kg/m3, only 35% of that of iron. This makes it one of the lightest metal material for various industries. Products like planes and vehicles are usually required to be as light as possible to reduce power consumption. Coupled with its lower price, the stock become popular substitute of copper and iron in many industries. Second, it can be strengthened. Its hardness can be coupled through cold working, and can compete with steel alloys if it’s combined with other elements like manganese, magnesium, copper, zinc etc and further heat-treated. Third, it’s easy to be processed.Aluminum coil stock is suited to be cast by any method like rolling, pressing, drawing etc. Fourth, industrial pure aluminum coil stock is corrosion resistant. A solid dense layer of protective film is always produced on the surface of aluminum coil stock, because aluminum has chemical reaction with oxygen easily. This protective film can not be destroyed unless they meet strong halide ions or basic ions. That’s why aluminum coil stock can firmly resist corrosion of industrial air, sea air, water, most acid materials and organics. Fifth, it does not become brittle at low temperature. Its hardness even become stronger below a temperature of 0o. Sixth, its heat and electricity conductivity ranks the fourth of all metals. The first three is silver, copper and gold. Seventh,it shows strong reflection of lights. The reflection rate for white light of its polished surface reaches 80% and above. Besides, it also performs good reflection property for infrared ray, UV, electromagnetic wave and heat radiation. The pure the coil stock, the higher the rate is. Eighth, industrial pure aluminum coil stock has no magnetism and withstands nuclear radiation. In spite of its wide application, industrial pure aluminum coil stock still has its advantages. The most influential one is that its hardness is not so satisfied as other types of aluminum alloys, which decides it can only be used in products requiring little about hardness.   6061 car chassis aluminum alloy price and factory Posted by: aluhm - 04-04-2018, 08:34 AM - Forum: Knowledge & Technique - No Replies The chassis is the vehicle’s main frame.
