Aluminum is a silvery white metal, the content in the crust is second only to oxygen and silicon in the third row.Density of small ingot aluminum, iron, copper is only *4.*1% of the *0.*3%, so it is also called light metal.Aluminum is the world second only to iron and steel consumption and output of nonferrous metals.The density of aluminum is only 2.***3 kg /m3, about steel, copper or brass density 1/3.Because the aluminum material is light, therefore, commonly used in the manufacture of automobile, train, ship, airplane, subway, rockets, spacecraft, sea and air transport, in order to reduce weight increase load.Aluminum is widely used in the military.Called ingots in our daily industrial material, according to the national standard (GB/T ********8) should be called "remelting aluminum ingot", but we used to call the "aluminum ingots".It is the use of cryolite alumina produced by electrolysis.Aluminum ingot after entering the industrial application has two kinds big: and deformation of aluminum alloy aluminum alloy casting.
