CNC machining molybdenum alloy heating elements
,TZM Mo-La vacuum furnace components
,custom precision CNC mechanical parts
As core components in high-temperature heat treatment equipment, our molybdenum alloy heating elements are manufactured using high-purity molybdenum base materials and special doping processes, designed specifically for extreme high-temperature environments. These elements can be used up to near melting point temperatures in hydrogen or dissociated ammonia atmospheres, and operate stably up to 2000°C in nitrogen environments.
Our precision CNC machining technology ensures dimensional accuracy and surface finish of each element, providing excellent creep resistance and dimensional stability at high temperatures.
The core advantage of molybdenum alloy heating elements lies in their high-temperature strength. When operating temperatures exceed 1700°C, we recommend using TZM alloy or molybdenum-lanthanum alloy with higher recrystallization temperatures and better strength.
| Feature Category | Specific Performance |
|---|---|
| High-Temperature Stability | Continuous operation for 2-3 years in 1700-2000°K range, extremely low vapor pressure in high-temperature vacuum environments |
| Oxidation Resistance | Dense oxide layer formation on surface, special models with MoSi2 coating for enhanced oxidation resistance |
| Mechanical Strength | TZM and Mo-La alloys maintain excellent creep resistance at high temperatures, dispersion-strengthened alloys show lower steady-state creep rates at 1800℃ |
| Corrosion Resistance | Resistance to hydrogen and dissociated ammonia corrosion, good ablation resistance in molten quartz environments |
| Machining Precision | Precision CNC machining ensures dimensional consistency and easy installation |
| Diversified Design | Available in various forms including wire, rod, strip, and tube, custom geometries supported |
