Molybdenum wires

Molybdenum wires for processing
This high-melting-point metal is easier to process than tungsten and is primarily used in high-temperature furnace components, lighting, and electron tubes. We offer a range of wire diameters and finishes to meet your specifications. Additionally, we provide TEM, a material with improved high-temperature deformation resistance achieved by incorporating trace elements, produced through our advanced, fully integrated production system starting from raw materials.

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

Materials guide

MOP It is the most conventional pure molybdenum material, exhibiting a high melting point, high-temperature strength, good thermal conductivity, a low coefficient of thermal expansion, and excellent workability.
MOS The MOS type improved coiling properties and an working range, achieved through adjustments to the composition at the raw material stage.
TEM This high-quality molybdenum material overcomes the brittleness and high-temperature deformation issues associated with conventional molybdenum. It exhibits excellent high-temperature deformation resistance, a high recrystallization temperature, and a wedge-shaped recrystallized structure. Even after high-temperature use, it retains excellent impact resistance and remains deformable at room temperature, offering greater bendability than pure molybdenum.
