Industrial uses
Titanium carbide in a molybdenum and nickelmatrix is formulated for high-temperature service.Tensile and compressive strengths, hardness,and oxidation resistance are high at1093°C. Critical parts for welding and thermalmetalworking tools, valves, seals, and hightemperaturegauging equipment are made fromgrades of this RHM.
