Fine Molybdenum Wire for Lighting
Fine molybdenum wire for lighting is a high-performance, ultra-fine wire specifically engineered for the lighting industry. It is widely used as lead wires, electrode wires, and support wires in halogen lamps, xenon lamps, metal halide lamps, tungsten-halogen infrared heaters, and other high-intensity gas discharge lamps. With excellent high-temperature mechanical strength, oxidation resistance, hermetic sealing capability, and precise formability, this material is essential for reliable operation in vacuum or gas-filled bulbs and serves as a critical component in modern energy-efficient light sources.

Material Features
High Melting Point and Thermal Strength
With a melting point of 2620 °C, molybdenum wire maintains mechanical integrity and dimensional stability under high-temperature conditions.
Excellent Vacuum and Inert Gas Compatibility
Exhibits extremely low vapor pressure and corrosion resistance in vacuum or inert gas environments (e.g., argon, xenon), preventing internal bulb contamination.
Matched Thermal Expansion Coefficient
Compatible with hard glass and quartz glass sealing materials, enabling reliable hermetic sealing.
Good Workability and Precision Formability
Can be drawn into ultra-fine diameters below 0.02 mm while retaining tensile strength and forming consistency, suitable for automated winding, welding, and crimping.
Excellent Surface Quality
Bright, oxide-free surface with high cleanliness, contributing to longer lamp life and improved luminous efficiency.
