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.Swissmetal alloy SM163N is a free-machining brass with good formability. Typical applications include any part made by a combination of machining and a light cold deformation such as thread rolling, bending, and/or riveting.
