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.Copper Alloy No. C35300 is a high-leaded brass (nominally 1.8% lead) that is noted for its excellent thread-rolling and knurling properties. It has a machinability rating approaching that of Free-Cutting Brass (Copper Alloy No. C36000). It is used in many screw-machine applications and has good resistance to corrosion in numerous environments. Among its many applications are clock and watch parts, wheels, gears and couplings.
