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.Neoquench-DR represents a family of Nd-Fe-B-base radially oriented anisotropic magnets manufactured by rapid quenching of material into flakes, which are then hot pressed to full density and hot formed into the final products by an advanced extrusion technique.
