Electrolytic aluminum is a method of smelting metallic aluminum. Usually aluminum oxide is decomposed into metallic aluminum by high current in an electrolytic tank.
Aluminum ingots are divided into high-purity aluminum ingots, aluminum alloy ingots and aluminum ingots remelted according to their composition. According to their shape and size, they can be divided into round ingots, plate ingots, strip ingots, T-shaped ingots, etc.
Aluminum is a silver-white metal that ranks third in the earth's crust after oxygen and silicon. Aluminum is known as a light metal due to its low density. Aluminum is a non-ferrous metal with high yield and wide application, second only to steel in the world. The density of aluminum is about 1/3 that of steel and copper.
Because aluminum is made of lightweight materials, it is often used in manufacturing, trains, subways, cars, airplanes, ships, rockets and other land, sea and air transportation vehicles to reduce dead weight and increase loading capacity. Likewise, aluminum plays an important role in military products.
