Molybdenum Wire.

Short Description:

Molybdenum wire is a long, thin wire made from molybdenum (Mo), a metal with a high melting point, high strength and excellent corrosion resistance. This wire is used in a wide range of applications in electronics, lighting (especially filaments), aerospace and high-temperature industrial furnaces because of its excellent electrical conductivity, thermal stability and corrosion resistance. The ability of molybdenum wire to remain physically and chemically stable at extreme temperatures makes it ideal for the manufacture of high-temperature heating elements and key components for electronic equipment. The production process involves melting, extruding and drawing to obtain high-quality molybdenum wire of the required diameter.
