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 6750 (formerly MBCo 241A) is a moderately high-strength wrought manganese bronze possessing good torsional properties and general corrosion resistance. The material possesses excellent hot-working properties and is readily joined by either soldering, brazing or oxyacetylene welding. Its many uses include automotive clutch disks, shafting and valve stems and bodies.
