High Temperature Molybdenum Wire
High temperature molybdenum wire is a specialized metallic wire designed to maintain structural integrity, electrical conductivity, and chemical stability in extreme thermal environments. With a melting point of 2620 °C and outstanding thermal resistance, it is widely used in high-temperature furnaces, aerospace components, glass sealing, crystal growth, and various heating elements.
1.Key Features
Excellent High-Temperature Strength
Performs reliably at temperatures up to 1900–2000 °C in vacuum or inert atmospheres without deformation or sagging.
Outstanding Thermal Stability
Maintains dimensional integrity and resists recrystallization over prolonged heating cycles.
High Purity (≥99.95%)
Ensures low outgassing, minimal contamination, and excellent electrical and thermal conductivity.
Good Workability
Can be coiled, cut, bent, or spot-welded into various shapes depending on application needs.
Oxidation Resistant in Protective Environments
Performs well in vacuum, argon, nitrogen, or hydrogen atmospheres; not recommended for direct air exposure above 400 °C.
