High-melting-point alloys of aluminium, magnesium, and copper are normally cast by this method, although other metals (including ferrous metals) can also be cast in this manner. Molten-metal temperatures start at about 600Â° C (1150Â°F) for aluminium and magnesium alloys and increase considerably for copper base and iron base alloys.

Magnesium alloy - Wikipedia
Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium is the lightest structural metal. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the
