What is the characteristic of aluminium alloy ingot

Aluminum is a silver-white metal, the third most abundant 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 known as light metal. Aluminum is the world's output and use are second only to iron and steel nonferrous metal. The density of aluminium is only 2.7103g/cm3, about a third of that of steel, copper or brass. Due to its light material, aluminum is often used in the manufacture of automobiles, trains, subways, ships, airplanes, rockets, spaceships and other land, sea and air vehicles to reduce the dead weight and increase the load.

Aluminum alloy ingots are made of pure aluminum and recycled aluminum, and other elements are added according to international standards or special requirements, such as silicon (Si), copper (Cu), magnesium (Mg), iron (Fe)... To improve the casting, chemical and physical properties of pure aluminum alloy.
