An aluminium ingot is a piece of relatively pure aluminium material, usually metal, that is cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods
The raw material in our daily industry is called aluminum ingot. According to the national standard (GB / T 1196-2008), it should be called "aluminum ingot for remelting", but we are used to calling it "aluminum ingot". It is produced by electrolysis of alumina cryolite. There are two types of aluminum ingots after they are used in industry: cast aluminum alloy and wrought aluminum alloy. Cast aluminum and aluminum alloy are the casting of aluminum produced by casting method; wrought aluminum and aluminum alloy are the processed products of aluminum produced by pressure processing method: plate, strip, foil, tube, bar, mold, wire and forging. According to the national standard "aluminum ingots for remelting are divided into 8 grades according to the chemical composition, which are al99.90, al99.85, al99.70, al99.60, al99.50, al99.00, al99.7e and al99.6e" (Note: the number after al is the aluminum content). Some people call "A00" aluminum, which actually contains 99.7% purity aluminum, is called "standard aluminum" in the London market. As we all know, China's technical standards in the 1950s were all from the former Soviet Union, "A00" is the Russian brand in the national standards of the Soviet Union, "a" is the Russian letter, not the English "a", nor the "a" of the Chinese Pinyin alphabet. If it is in line with international standards, it is more accurate to call it "standard aluminum". Standard aluminum is ingots containing 99.7% aluminum, which is registered in the London market
