Black Molybdenum Wire
Black molybdenum wire is a high-performance molybdenum product characterized by its dark oxide-coated surface, formed through high-temperature annealing in a controlled atmosphere. This wire is widely used in applications requiring excellent high-temperature strength, thermal stability, and oxidation resistance—particularly in the electronics, vacuum furnace, lighting, and crystal growing industries.
1.Key Features
Oxide-Coated Surface: Enhances resistance to surface oxidation during storage and handling
High Temperature Strength: Maintains mechanical integrity up to 1900?°C in vacuum or inert gas
Good Ductility and Straightness: Easy to coil, weld, or process for component fabrication
Stable Electrical Conductivity: Suitable for use in high-vacuum electronic applications
Economical: More cost-effective than polished molybdenum wire, ideal for structural uses
