Common W-Mo Uses in Vacuum Furnaces
Tungsten and molybdenum are commonly used for hot-zone, support and load-bearing parts in vacuum furnaces. Final material selection should consider temperature, atmosphere, load and structure.
Typical Components
Common forms include plates, rods, wires, boats, crucibles, heat shields, fasteners and drawing-based parts.
- Molybdenum heat shields, heating strips and supports
- Tungsten crucibles, boats and high-temperature load-bearing parts
- Connectors, threaded rods and frames made to drawing
Information Required for Selection
Tungsten and molybdenum are not interchangeable in every furnace condition.
- Maximum temperature and working duration
- Vacuum level, protective atmosphere and contact media
- Dimensions, tolerances, surface condition and assembly
- Thermal cycling, impact load and deformation limits
Inquiry Recommendation
Provide drawings, material grade, quantity, furnace type, operating temperature and delivery requirements. Photos and key dimensions can be used for initial discussion when drawings are unavailable.
