Black Molybdenum Wire
Widely used in drawing die, casting mold, gate, high temperature stirring rod, high-temperature pad, high-temperature structural parts, support parts, electron tube shed pole, incandescent lamp hook, winding PL wire, vacuum or protective atmosphere high-temperature furnace heating material support rod, lead line, gate, etc.
The use of molybdenum is not large, vacuum tubes are mainly used to manufacture cathodes, anodes, bulbs within tungsten brackets, etc. In 1927, ultrapure molybdenum metal, with a purity of 99.999%, enabled people to pull into filaments, in addition to the wires used, metal molybdenum wire EDM was also used. In recent years, CNC EDM is made in China and is made of conductive metal cut molybdenum wire - inert gas shielded, molybdenum wire, tungsten wire, can be formulated into high-temperature thermocouples, used to measure high temperatures of 1200-2000 °C.
