Molybdenum alloys
Mo-Ti-Zr refractory alloy (TZM) with 2,623 °C melting point, designed to operate between 700 °C and 1,400 °C in non-oxidizing atmospheres, with refined grain vs. pure molybdenum.
Characteristics
Family characteristics
- Composition: Mo (~99%), Ti (~0.5%), Zr (~0.1%)
- Operating range 700–1,400 °C in non-oxidizing environments
- Melting point 2,623 °C
- Refined grain structure — better weldability
- Resistance to fluoride salts above 1,300 °C
Typical applications
Typical applications
- Hot-chamber die-casting tips
- High-temperature operations (up to 1,400 °C)
- Alternative to beryllium copper where higher abrasion and thermal conductivity matter
