Alumina, also known as aluminum oxide, is in the form of a white powder. Electrolytic aluminum is a method of smelting metallic aluminum, which is usually decomposed into metallic aluminum by a large current in an electrolytic cell.

       The primary aluminum is a liquid aluminum liquid which is taken out during the electrolysis process and is not subjected to precipitation or the like. The primary aluminum can be turned into an aluminum ingot by being cooled in the body of the cast aluminum ingot model. Therefore, alumina is the raw material for the aluminum liquid, electrolytic aluminum is the process, primary aluminum is the aluminum liquid in the electrolysis process, and aluminum ingot is an aluminum product, which is finally sold in the market.

       Aluminum ingots are classified into high-purity aluminum ingots, aluminum alloy ingots and remelting aluminum ingots according to their composition; they can be divided into round ingots, ingots, ingots, T-shaped ingots, etc. according to their shape and size.
