Molybdenum Alloy Heating Element Processing Case Study
2025-11-03
Product Overview
Molybdenum alloy heating elements are critical components in high-temperature industrial applications, leveraging molybdenum’s exceptional melting point (2,623°C) and stability under extreme conditions. These elements are precision-engineered via CNC machining China expertise to ensure dimensional accuracy and performance in environments exceeding 1,700°C, such as vacuum furnaces and glass melting systems. Customized from alloys like TZM (Titanium-Zirconium-Molybdenum) or Mo-La (Lanthanum-Oxide-Doped), they combine high thermal conductivity, low vapor pressure, and resistance to deformation.
Key Features
- High-Temperature Resilience: Operates reliably up to 2,000°C in inert or vacuum atmospheres, with minimal thermal expansion.
- Superior Machinability: Precision CNC machining enables complex geometries (rods, coils, strips) while maintaining tight tolerances (±0.01–0.05 mm).
- Oxidation Resistance: Performs optimally in controlled atmospheres (e.g., hydrogen or nitrogen), reducing contamination risks.
- Customization Flexibility: Tailored designs for aerospace, semiconductor, and glass industries, supported by wire EDM and laser cutting.
