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.Olin alloy 186 is a new alloy that provides high thermal stability for elevated-temperature connector applications. This alloy provides exceptional resistance to loss in contact because of its excellent resistance to stress relaxation.
