Common Sense of Aluminum
Aluminum according to the national standard (GB/T1196-93) should be called "aluminum ingots for remelting", but we used to call "aluminum ingot". It is produced by electrolysis.
After entering the industrial application of aluminum ingot has two categories: and deformation of aluminum alloy aluminum alloy casting. Casting of aluminum and aluminum alloy with casting method for producing aluminum castings; wrought aluminum and aluminum alloy is processed products the production of aluminum by pressure processing method: plate, belt, foil, pipe, bar, line, and forgings. According to the « aluminum ingots for remelting; » national standards, "according to the chemical composition of aluminum ingots for remelting is divided into 6 grades, respectively is Al99.85, Al99.80, Al99.70,Al99.60, Al99.50, Al99.00"
At present, people call the "A00"aluminum; aluminum is actually 99.7% purity aluminum, called "the standard of aluminum in the London market". As we all know, our country in the fifty's technical standards are from the former Soviet Union, "A00" isthe national standards in the Russian brand, "A" is the Russian alphabet, rather than English "A" word, nor the Chinese phonetic alphabet "A". And the international community, called "standard" is more accurate. Standard aluminum is aluminum ingot containing 99.7%, registered in the London market is that it.
