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 ZW3 is a high strength wrought magnesium alloy. It shows improved hot formability; it is free from stress corrosion cracking in service and is readily weldable by the argonarc and heliarc machine processes and by the manual method for simple joints.
