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.MUELLER Alloy 2300 is an alpha brass containing 15% zinc. It has good physical and mechanical properties, excellent cold-working characteristics and a pleasing red color. Its low zinc content makes it resistant to dezincification and it is more resistant to stress-corrosion cracking than brasses with higher zinc contents. Typical uses are plumbing pipe and condenser and heat-exchanger tubes.
