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 ZW1 is similar to ELECTRON ZW3 but with reduced zinc content to confer complete freedom from junction cracking in manual argonarc or heriarc welding, with but small sacrifice in strength properties.
