Description of TZM Molybdenum Rods
TZM Molybdenum Rods are a kind of superalloy rod commonly used in molybdenum base Alloy, which is mainly made by vacuum arc melting, powder metallurgy, rolling, forging, and grinding.
TZM Molybdenum Rods have various advantages of molybdenum alloy, such as high temperature strength, good dimensional stability, excellent heat resistance, high thermal and electrical conductivity, low coefficient of thermal expansion, good corrosion resistance, low energy consumption and long service life.
Compared with pure molybdenum bars, TZM Molybdenum Rods have excellent high-temperature strength and comprehensive properties, and can be widely used in the manufacture of various high-temperature tools, molds, and various high-temperature structural parts (aerospace, electronics, ceramic processing industry, chemical industry, and high-temperature furnace industry).

Manufacturing Process of TZM Molybdenum Rods
Smelting: The Vacuum sintering method is adopted, sintering temperature is 1440℃, relative density can reach 99.2%, tensile strength is 1086.7 MPa, elongation is 22.8%.
Processing: After turning, the surface shall not have defects such as holes, cracks, delamination, or inclusions.
Features of TZM Molybdenum Rods
Ultra-high melting point and high temperature strength
The melting point is as high as 2610°C, and it still maintains high strength (more than 30% better than pure molybdenum) in the range of 1200°C~1600°C, and has excellent creep resistance.
Excellent thermal shock resistance
Low thermal expansion coefficient (4.8×10⁻⁶/°C) and high thermal conductivity (142 W/m·K), can withstand rapid temperature changes (such as thermal shock during rocket engine ignition).
Good corrosion resistance
Resistant to molten metals (such as copper and aluminum), excellent stability in non-oxidizing atmospheres (such as vacuum and inert gas), but requires coating protection in oxidizing environments.
