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.AMPCOLOY 90 is a cast copper with a good combination of electrical and thermal conductivity and resistance to corrosion. It has low room-temperature strength and medium-to-good ductility. These characteristics make it highly suitable for many applications requiring good electrical and thermal conductivity combined with good resistance to corrosion and oxidation.
