Molybdenum rods
High performance grades available for furnace components, heaters, etc.
It is available not only in molybdenum wires but also in bars form. Taking advantage of its high melting point and easier processability than tungsten, molybdenum wires are mainly used for high-temperature furnace parts. Various wire diameters and finishes are available depending on the application. We also offer materials with strengthen performance by adding trace elements (TEM), taking advantage of our integrated production system from raw material to finished product.

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. |
