[China Aluminum Industry Network] Aluminum is a silver-white metal, which ranks third in the earth's crust after oxygen and silicon. Aluminum has a low density and is called light metal. Aluminum is a non-ferrous metal with high output and usage. It is second only to steel in the world. The density of aluminum is about 1/3 of that of steel and copper. Due to the lightness of aluminum, it is commonly used in land, sea, and air transportation in manufacturing, trains, subways, automobiles, airplanes, ships, and rockets to reduce its own weight and increase its load. Similarly, aluminum has a significant position in military products.
Aluminum oxide, also known as aluminum oxide, is a white powder. Electrolytic aluminum is a method of smelting metallic aluminum. Usually, aluminum oxide is decomposed into metallic aluminum by a large current in an electrolytic cell.
Primary aluminum is a liquid aluminum liquid that is extracted during electrolysis and has not been treated by precipitation or the like. The primary aluminum can be used as an aluminum ingot by in-body cooling of the aluminum ingot model. Therefore, alumina is a raw material for the extraction of aluminum liquid, electrolytic aluminum is a process, and primary aluminum is an aluminum liquid in an electrolytic process, and an aluminum ingot is an aluminum product, which is a saleable product that is finally sold in the market.
Aluminum ingots are divided into high-purity aluminum ingots, aluminum alloy ingots and remelted aluminum ingots according to different components; they can be divided into round ingots, plate ingots, bar ingots, and T-shaped ingots according to their shapes and sizes.
