Molybdenum Wire for Heating
Molybdenum wire for heating is a high-purity molybdenum wire specifically designed for high-temperature electric heating applications. It is widely used as a heating element in vacuum furnaces, hydrogen reduction furnaces, crystal growth furnaces, sintering furnaces, and other thermal processing equipment. With an exceptionally high melting point, stable electrical resistivity, and excellent thermal durability, molybdenum wire operates reliably in extreme environments such as high vacuum or reducing atmospheres, making it an ideal alternative to conventional heating materials under demanding conditions.

Material Features
Extremely High Melting Point and Thermal Strength
With a melting point of 2620 °C, molybdenum wire maintains mechanical strength and resists creep even during prolonged operation above 1700 °C.
Stable Electrical Resistivity
Offers consistent electrical resistance, allowing precise control of heating efficiency, temperature stability, and ramp-up rates.
Excellent Thermal Stability and Oxidation Resistance (in Protective Atmospheres)
Chemically stable in vacuum or reducing gases like hydrogen, exhibiting low oxidation and minimal volatilization.
High Dimensional Precision
Available in various diameters from 0.1 mm to 3.0 mm, with excellent roundness and straightness to accommodate different heater designs.
Superior Workability
Can be cold drawn, coiled, or shaped into heating structures such as spiral wires, U-shaped wires, or frame elements for easy installation and replacement in furnaces.
