The meaning of ingot
     Aluminum, on our day-to-day industrial raw material called aluminum ingots, according to the National Institute of Standards (GB/T1196-93) should be called the "use of aluminum ingot remelting," but we used to call "ingot." It is made of alumina - through cryolite produced by electrolysis. Aluminum ingots into industrial applications after two broad categories: cast aluminum and aluminum alloy deformation. Cast aluminum and aluminum alloy casting method is based on the production of aluminum castings; deformation of aluminum and aluminum alloy pressure on the production process of aluminum processing products: plate, belt, foil, tube, bar, type, line and forgings. In accordance with? Ingot remelting use? National standards, "according to the ingot remelting use chemical composition is divided into 6 grades, which are Al99.85, Al99.80, Al99.70, Al99.60, Al99.50, Al99. 00 "(Note: Al figures are after the aluminum content). At present, it was called the "A00" aluminum, is actually 99.7 percent pure aluminum to aluminum, the London market, "the standard aluminum." We all know that our technical standards in the 1950s from the former Soviet Union, "A00" is the national standard of the Soviet Union in the Russian brand, "A" is the Russian alphabet, rather than in English "A" word, the Chinese phonetic alphabet is not The "A". And international practice, "the standard aluminum" is more precise. Aluminum is the standard with 99.7 percent of aluminum ingot, the London market, it is registered.
