The Alumold® 500 alloy has been optimised to provide excellent machinability, good shape stabilityand high strength properties throughout the plate thickness. Uniform strength is an important property for mould and tool construction. Typical applications include compression or injection moulds for plastics.
Alumold® 500 is based on an alloy of the 7000 series.
