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.ELECTRON Z5Z is a heavy duty magnesium alloy for structural purposes at normal temperatures. It is characterized by high yield strength with good elongation, high fatigue strength with very low notch sensilivity, and uniform strength in varying sections.
