The raw materials in our daily industry are called aluminum ingots according to the national standard (GB/T 1196-2008), but everyone is accustomed to calling it "for remelting".
It is produced by electrolytic alumina-cryolite. After aluminum ingots enter industrial application, there are two categories: cast aluminum alloy and deformed aluminum alloy. Cast aluminum and aluminum alloys are castings produced by casting methods.
Wrought aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods: plates, strips, foils, tubes, rods, dies, wires and forgings. According to national standards, "for remelting" is divided into 8 grades according to chemical composition, namely aluminum 99.90, aluminum 99.85, aluminum 99.70, aluminum 99.60, aluminum 99.50, aluminum 99.00, aluminum 99.7E, aluminum 99.6E" (Note: after aluminum The number is the aluminum content). Some call it "A00" aluminum, which is actually 99.7% pure aluminum and is called "standard aluminum" in the London market.
