Molybdenum rods
High-performance grades are available for furnace components, heaters, etc.
It is available not only as molybdenum wires but also as bars. Leveraging its high melting point and easier processability compared to tungsten, molybdenum wires are primarily used for high-temperature furnace components. Various wire diameters and finishes can be provided to suit specific applications. Additionally, we offer materials with enhanced performance through the addition of trace elements (TEM), benefiting from our integrated production system from raw materials to finished products.

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. |
