What is Aluminum?
Aluminium is a silvery white metal, second only to oxygen and silicon in the earth's crust, and ranks third.
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 the world's output and consumption of ferrous metals only next to steel.
The density of aluminum is only about 2.7103g/cm3, about 1/3 of the density of steel, copper or brass.
Because of its lightweight material, aluminum is commonly used in the manufacture of automobiles, trains, subways, ships, aircraft, rockets, ships and other land and air vehicles to reduce deadweight and increase loading capacity.
