Industrial raw material aluminum is usually called aluminum ingot. According to the national standard (GB/T 1 196-93), it should be called "aluminum ingot for remelting", but everyone is used to it. It is produced by electrolysis with alumina-cryolite.
There are two kinds of aluminum ingots after entering industrial application: cast aluminum alloy and forged aluminum alloy.
Casting aluminum and aluminum alloy are aluminum castings produced by casting method; Deformed aluminum and aluminum alloys are processed products that produce aluminum through pressure processing: plates, strips, foils, pipes, bars, molds, wires and forgings. According to the national standard of aluminum ingots for remelting, "aluminum ingots for remelting are divided into six grades according to chemical composition, namely, al99.85, Al99.80, Al99.70, Al99.60, Al99.50 and Al99.00" (note: the number after Al is aluminum content).
What some people call "A00" aluminum is actually aluminum with a purity of 99.7%, which is called "standard aluminum" in the London market. As we all know, China's technical standards in the 1950s all came from the former Soviet Union. "A00" is a Russian brand in Soviet national standards, and "A" is a Russian letter, not an English "A" or a Chinese phonetic alphabet. In line with international standards, it is more accurate to call it "standard aluminum". Standard aluminum is an aluminum ingot with 99.7% aluminum content, registered in London market.
