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 3406 (formerly MBCo. Alloy 314) is a medium-leaded brass alloy intended for screw-machine applications where excellent thread-rolling, knurling and cold-forming properties are required. It is characterized by an excellent combination of cold-working and free-machining properties. Among its many applications are valve stems, gears, rivets and threaded connectors.
