Material Notes:
Pouring Temperature: 1095-1175°CHeat treatment required for max strength (Annealing): 870-900°C/water quenchHeat treatment required for max strength (Hardening): 870-900°C/water quenchDescription: The unique combination of physical and mechanical properties of copper beryllium casting alloys provide a dynamic range of metallurgical alternatives to meet specific performance requirements. The inherent strength, hardness, conductivity, and castability of these materials make them ideal for applications which require a high performance engineered material solution. Advancements in component casting technology and proprietary material production technology pioneered by Brush Wellman have resulted in BrushCAST™ alloys being a cost effective design choice.Alloy 3C offers excellent electrical and thermal conductivity, good strength & galling resistance, and accurate replication of component detail. Alloy 3C offers nearly 3 times the conductivity of the high strength alloys, twice the thermal conductivity of aluminum alloys, and ten times that of steel.Information supplied by Brush Wellman Engineered Materials.Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
