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.FERRO-TIC Gr. CM is a machinable grade of cemented carbide which can be hardened by oil quenching after machining to shape. It is hardened to Rockwell C66-70 and exhibits excellent abrasion resistance. It is recommended for heavy cold heading or forming dies.
