A 7000 series aluminium alloy that has successfully replaced steel in many mould applications. It combines high thermal conductivity, resistance, ease of machining and polishing, dimensional stability and consistency across the entire thickness of the plate. The use of this material results in reduced operating costs and increased production of parts. Alumold®-500 moulds should have a maximum operating temperature of 110 ° C and a partition line stress of 5000 PSI (nominal) and 7200 PSI (maximum).
