Aluminum is a silver-white metal, ranking third in content in the earth's crust after oxygen and silicon. The density of aluminum is small, only 34.61% of iron and 30.33% of copper, so it is also called a light metal. Aluminum is a non-ferrous metal second only to steel in terms of output and usage in the world. The density of aluminum is only 2.7103g/cm³, which is about 1/3 of the density of steel, copper or brass. Because aluminum is light, it is often used in the manufacture of land, sea and air vehicles such as cars, trains, subways, ships, airplanes, rockets, and spaceships to reduce weight and increase load capacity.
Industrial aluminum ingots
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 everyone is used to calling it "aluminum ingot". It is produced by electrolysis from aluminum oxide-cryolite. After aluminum ingots enter industrial application, there are two major categories: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloys are aluminum castings produced by casting methods; deformed aluminum and aluminum alloys are processed aluminum products produced by pressure processing methods: plates, strips, foils, tubes, rods, molds, wires and forgings. According to the national standard "Aluminum ingots for remelting are divided into 8 grades according to their chemical composition, namely 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). What some people call "A00" aluminum is actually aluminum with a purity of 99.7%. It is called "standard aluminum" in the London market. Everyone knows that our country's technical standards in the 1950s came from the former Soviet Union. "A00" is the Russian brand name in the Soviet national standard. "A" is the Russian letter, not the English "A" word, nor the Chinese pinyin letter. If "A" is in line with international standards, it is more accurate to call it "standard aluminum". Standard aluminum is an aluminum ingot containing 99.7% aluminum, and it is registered on the London market.
Aluminum alloy ingot
definition
