Manufacturing begin with high grade al alloy containing 97 percent al.
A furnace heats the ingots -750 degrees Celsius. They liquefy in about 25 minutes. The molten al then flows directly to a mixer in which they inject argon gas which enables them to remove the hydrogen. This increases the density making the al less porous when solidified after adding powdered Ti ,Mg and other metallic elements to further strengthen the al. they blend in flux at chemical which draws al oxide to the surface . They skim off this impurity along with the flux and the liquid al is ready for casting.
