Good Quality Rectangular Pure Aluminum Ignot Aluminum Alloy Ingot 6063

The raw material in our daily industry is called aluminum ingot, which should be called "aluminum ingot for remelting" according to the national standard (GB/T 1196-2008), but everyone is used to calling it "aluminum ingot". It is produced by electrolysis using alumina-cryolite. After aluminum ingots enter industrial applications, there are two categories: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloys are aluminum castings produced by casting methods; wrought aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods: plates, strips, foils, tubes, rods, shapes, 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, Al99. 6E" (Note: The number after Al is the aluminum content).

Some people call "A00" aluminum, which is actually aluminum with a purity of 99.7%, which is called "standard aluminum" in the London market. Everyone knows that our country’s technical standards in the 1950s all came from the former Soviet Union. "A00" is the Russian grade in the Soviet Union's national standards, and "A" is the Russian letter, not the English "A" word, nor the Chinese pinyin alphabet. 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, which is registered on the London market.

Aluminum is a silver-white metal, and its content in the earth's crust ranks third 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 light metal. Aluminum is a non-ferrous metal that is second only to steel in terms of output and consumption 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. Due to the light material of aluminum, it is often used in the manufacture of land, sea and air vehicles such as automobiles, trains, subways, ships, airplanes, rockets, and spaceships to reduce its own weight and increase its loading capacity.
