What is aluminum ingot

Aluminum, the raw material of our daily industry is called aluminum ingot, according to national standards (GB/T1196-93) should be called "remelting aluminum ingot," but everyone used to call "aluminum ingot." It is produced by electrolytic method using alumina-cryolithite. There are two major categories of aluminum ingots after they have entered industrial applications: cast aluminum alloys and deformed aluminum alloys. Foundry aluminum and aluminum alloys are castings that produce aluminum by casting; deformed aluminum and aluminum alloys are processed products that produce aluminum by pressure processing methods: plates, strips, foils, tubes, rods, patterns, wires, and forgings. In accordance with the national standard for remelting aluminum ingots, "remelting aluminum ingots are divided into six grades based on 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, what is called "A00" aluminum is actually aluminum with a purity of 99.7% aluminum, which is called "standard aluminum" in the London market. As we all know, China’s technical standards in the 1950s came from the former Soviet Union. “A00” is a Russian trademark in the Soviet Union’s national standards. “A” is a Russian alphabet, not an English “A”, or a Chinese phonetic alphabet. The "A". In line with international standards, it is more accurate to call "standard aluminum." Standard aluminum is an aluminum ingot containing 99.7% aluminum, which is registered in the London market.
