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 ZREO is a medium strength magnesium base casting alloy of very similar creep resistance to Elektron ZRE1 It possesses optimum corrosion resistance in marine type exposure environments with freedom from sporadic deep pitting combined with good castability.
