ã€China Aluminum Industry Network】 Aluminum, our daily raw material for industrial use is called aluminum ingots. According to the national standard (GB/T1196-93), we call “aluminum ingots for remeltingâ€, but we call it “ingotsâ€. It is produced by electrolytic method using alumina-crylylite. There are two major categories of aluminum ingots after they are used in industry: forged aluminum alloys and deformed aluminum alloys. Forged aluminum and aluminum alloys are forgings that produce aluminum castings; deformed aluminum and aluminum alloys are processed products that produce aluminum from pressure processing methods: plates, strips, foils, tubes, rods, patterns, wires, and forgings. According to the National Standard for Remelting Aluminum Ingots, "The remelted aluminum ingots are divided into six trademarks based on their chemical composition: 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. We all know that China’s technical specifications in the 1950s came from the former Soviet Union. “A00†is a Russian trademark in the Soviet national standard. “A†is a Russian alphabet, not the English “A†word, nor is it a Chinese phonetic alphabet. The "A". When it is in line with the world, it is more appropriate to say "regulate aluminum." Specification aluminum is an aluminum ingot containing 99.7% aluminum, which is registered in the London market.
