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.Elektron RZ5 is a variant of Elektron Z5Z with slightly lower tensile properties but better casting characteristics and is used for structural purposes at normal temperatures. It is recommended for difficult spidery castings. It is weldable by the argonarc process.
