Material Notes:
moldMAX XL® is a unique spinodally hardened copper-nickel-tin alloy that combines high strength and high thermal conductivity. Available in large plate thickness up to 12” and in rounds up to 23.5”, moldMAX XL® can be used as a direct replacement for P-20 tool steels. moldMAX XL® provides an exciting combination of strength and thermal conductivity – the strength of prehardened tool steels and the high conductivity of copper – in larger cross sections for bigger molds. For large tools, this combination provides unbeatable economic value for the molder, and the excellent machinability means metal removal rates are high as well. Machines 5 times faster than P-20 steel. The high strength and hardness ensures that moldMAX XL® tools will provide durability as well as efficiency.Information supplied by Brush Wellman Engineered Materials.Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
