What Is Aluminum Ingot
Aluminum, our daily industrial raw materials called aluminum ingots, according to the national standard (GB/ t1196-93) should be called "remelting aluminum ingots", but we used to call "aluminum ingots". It is produced by electrolysis of alumina and cryolite. There are two kinds of aluminum ingots after they are used in industry: forged aluminum alloy and deformed aluminum alloy. Wrought aluminium and aluminium alloys are castings produced by forging; Deformation of aluminum and aluminum alloy is produced by pressure processing of aluminum processing products: plate, tape, foil, pipe, bar, type, wire and forging. According to the national specification of remelting aluminum ingots, "remelting aluminum ingots are divided into 6 trademarks according to their chemical composition, namely Al99.85, Al99.80, Al99.70, Al99.60, Al99.50 and Al99.00" (note: the number after Al is aluminum content). At present, some people call "A00" aluminum, in fact, aluminum containing 99.7% purity, in the London market called "standard aluminum". As we all know, in the 1950s, China's technical specifications were all from the former Soviet union, and "A00" was the Russian trademark in the national specifications of the Soviet union. With the word of world line, say "normative aluminium" more appropriate. Standard aluminium is aluminium ingots containing 99.7 per cent aluminium and is registered on the London market.
