In our daily industry on the raw materials called aluminum ingot, by national standards (GB/T 1196-2008) should be called "remelting with aluminum ingot", but everyone used to "aluminum ingot". It is produced by electrolysis using alumina - cryolite. Aluminum ingots into industrial applications after two categories: cast aluminum alloy and deformed aluminum alloy. Cast aluminum and aluminum alloy are aluminum castings produced by casting method; Deformed aluminum and aluminum alloys are processed products that produce aluminum by pressure machining: plates, strips, foils, tubes, rods, shapes, wires and forgings. According to the national standard, "aluminum ingot for remelting is divided into 8 grades according to its chemical composition, which are Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, AL99.7E, AL99.6E "(Note: the number after Al is aluminum content). Some people call it "A00" aluminum, but it's actually 99.7 percent pure aluminum, and it's called "standard aluminum" on the London market.
