It is the most abundant metal element in the earth's crust. Aluminum ingots need to be melted when they are produced. The products are often made into rods, sheets, foils, powders, strips and wires. The aluminum ingots are mostly melted in aluminum melting furnaces that use natural gas or liquefied petroleum gas as fuel, which has good economic and environmental protection.
