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.MONEL* alloy 450 is a 70-30 cupro-nickel with certain minor elements controlled to improve weldability. The alloy resists attachment of bio-fouling organisms. It resists stress-corrosion cracking in seawater environments.
