View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.Copper Alloy No. C96600 is a cast copper-tin-lead-zinc alloy also known as 87-10-1-2 alloy. It is characterized by a good combination of strength, machinability and resistance to corrosion. This alloy is often used to make castings for valves and pumps which are subject to liquid and gas pressure and, therefore, must be free from internal porosity, shrinkage or other defects.
