Material Notes:
Pouring Temperature: 1010-1120°CHeat treatment required for max strength (Annealing): 760-790°C/water quenchHeat treatment required for max strength (Hardening): 760-790°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.BrushCAST™ high strength casting alloys are available in fine grain equivalents. Material properties and manufacturing characteristics are similar to those of the standard casting alloys. Grain refinement is achieved through precise additions of either cobalt or titanium. Our fine grain casting alloys are preferred in applications where excellent surface finish characteristics are required in the cast product.Information supplied by Brush Wellman Engineered Materials.Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
