Detailed description :

 to use the electrolytic method to electrolyze non-ferrous metals production of metal products, main component is commonly aluminum.

Because there are many excellent properties of aluminum, and electrolytic aluminum has a very wide range of USES. (1) the density of aluminum is small, only 2.7 g/cm3, although it is soft, but can be made into all kinds of aluminum alloy, such as hard, hard aluminum, aluminum antirust aluminum, cast aluminum, etc. The aluminum alloy is widely used in aircraft, cars, trains, ships and other manufacturing industries. In addition, the space rocket, the space shuttle, the satellite also USES a large number of aluminum and its alloys. For example, a supersonic plane of aluminum and its alloys by about 70%. Also extensive use of aluminum in ship building, a large passenger ship with aluminum amount often of thousands of tons.

(2) the electrical conductivity of the aluminum is second only to silver, copper, although its conductivity is only two-thirds of copper, but the density is only 1/3 of the copper, so conveying the same amount of electricity, the quality of aluminium wire is only half of the copper wire. On the surface of the aluminum oxide film not only have the ability of corrosion resistance,
