Molybdenum Wire Description
Molybdenum Wire is made from pure molybdenum or TZM (titanium-zirconium-molybdenum) alloys. It comes in various forms, such as black molybdenum wire, white molybdenum wire, sprayed molybdenum wire, and wire-cutting molybdenum wire.
This wire is well-suited for high-temperature furnaces and as a support material in heating wire mesh. Additionally, its exceptional properties, such as high thermal conductivity and resistance to wear, make it a preferred choice in filaments, electronic components, and superalloys. Industrial-grade molybdenum is also valued for its stability under extreme pressures and temperatures, as well as its ability to form hard carbides for steel alloys.
