Molybdenum wires

Molybdenum wires for processing

Molybdenum has high melting point as same as tungsten but is easier to be processed. It is mainly used for high-temperature furnace parts, lighting, and electron tube. We have various wire diameters and finishing according to the application. We also offer special materials that have higher performance by adding trace elements (TEM),in our integrated production.

Product selection guide

MOP The most common pure molybdenum material with high melting point, high temperature strength, good thermal conductivity, low thermal expansion coefficient and excellent workability.
MOS General molybdenum materials may cause pitch irregularities when grids are formed with  high-speed coil winders. For the MOS type, we improved coiling performance and working range by adjusting components starting at the raw material stage.
TEM A high quality molybdenum material that has overcome the disadvantages of conventional molybdenum brittleness and deformation at high temperature. It has excellent high temperature deformation resistance, high recrystallization temperature, and wedge-shaped recrystallized structure. It is excellent in impact resistance even after being used at high temperature; it also allows for deformation processing at normal temperature, with foldability larger than pure molybdenum.
