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 alumina-cryolite. After aluminum ingots enter into industrial applications, there are two categories: cast aluminum alloys and deformed aluminum alloys.
1.Aluminum ingot for remelting–15kg, 20kg (≤99.80%Al):
2.T-shaped aluminum ingot–500kg, 1000kg (≤99.80%Al):
3.High-purity aluminum ingot–l0kg, 15kg (99.90%～99.999%Al);
4.Aluminum alloy ingot–10kg, 15kg (Al–Si, Al–Cu, Al–Mg);
5.Plate ingot–500～1000kg (for plate making);
6.Round ingot–30～60kg (for wire drawing)
Aluminum is a silver-white metal, the third most abundant in the earth’s crust after oxygen and silicon. The density of aluminum is relatively small, only 34.61% of iron and 30.33% of copper, so it is also called a light metal. Aluminum is the world’s largest non-ferrous metal after steel in production and consumption. 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, planes, rockets, spaceships, etc., in order to reduce the self-weight and increase the loading capacity.
