Molybdenum wires

Molybdenum wires for processing
It is a high-melting-point metal that is easier to process than tungsten, and is mainly used for high-temperature furnace components, lighting, and electron tubes. Various wire diameters and finishes are available to meet your needs. We also offer TEM, a material with higher resistance to high-temperature deformation by adding trace elements, taking advantage of our sophisticated production system that starts from raw materials.

Applications Filaments for halogen lamps,
Electrodes for projector lamps, etc.

Materials guide

MOP It is the most conventional pure molybdenum material and has a high melting point, high temperature strength, good thermal conductivity, low coefficient of thermal expansion, and excellent workability.
MOS MOS type has improved coiling property and working range by adjusting the composition from the raw material stage.
TEM This high-quality molybdenum material overcomes the brittleness and deformation at high temperatures of conventional molybdenum. It has excellent high-temperature deformation resistance, a high recrystallization temperature, and a wedge-shaped recrystallized structure. Even after use at high temperature, it has excellent impact resistance and can be deformed at room temperature. It also has greater bendability than pure molybdenum.
