What is aluminum ingot

【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 remelting”, but we call it “ingots”. 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.

Coal is the dominant mineral resource in Ningxia. The distribution area of coal-bearing strata in this area is 17,000 square kilometers, accounting for a quarter of the total area of Ningxia. coal has been hailed as black gold, industrial food. Elements that form the coal's organic matter are mainly carbon, hydrogen, oxygen, nitrogen and sulfur, in addition, there is a very small amount of phosphorus, fluorine, chlorine and arsenic and other elements.
