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.MT-104 is a powder-metallurgical molybdenum alloy which was developed for applications requiring hardness and high-temperature properties superior to those of unalloyed molybdenum. When wrought, MT-104 is a precipitation-strengthened material with high-temperature properties similar to those of arc-cast TZM, which has the same composition. Suggested uses are dies for extrusion, hot pressing, and die casting and for a wide structural components that operate at high temperatures.
