Aluminum ingots are divided into three types according to their composition: aluminum ingots for remelting, high-purity aluminum ingots and aluminum alloy ingots; According to shape and size, it can be divided into bar ingot, round ingot, plate ingot, T-shaped ingot and so on.
Several common aluminum ingots
Aluminum ingot for remelting -- 15kg, 20kg (≤ 99.80% Al):
T-shaped aluminum ingot -- 500kg, 1000kg (≤ 99.80% Al):
High purity aluminum ingot -- 10kg, 15kg (99.90% ~ 99.999% Al);
Aluminum alloy ingot -- 10kg, 15kg (Al -- Si, Al -- Cu, Al -- mg);
Plate ingot -- 500 ~ 1000kg (for plate making);
Round ingot -- 30 ~ 60kg (for wire drawing).
Aluminum is a silvery white metal, ranking third in the earth's crust after oxygen and silicon. Aluminum has a small density, only 34.61% of iron and 30.33% of copper, so it is also called light metal. Aluminum is a non-ferrous metal whose output and consumption are second only to steel in the world. The density of aluminum is only 2.7103g/cm ³, About 1 / 3 of the density of steel, copper or brass. Because of its light material, aluminum is often used to manufacture land, sea and air vehicles such as automobiles, trains, subways, ships, aircraft, rockets and spaceships to reduce their own weight and increase their loading capacity.
