Prolific Heating International Co., Ltd is a distributor of Molybdenum Heater from A.L.M.T Co., Ltd. Our supplier is a top manufacturer for processing technologies of tungsten and molybdenum products. Molybdenum Heater element can withstand high temperature and corrosion, used in high-temperature resistance furnace.
Advantages of Using Molybdenum Heater
Molybdenum is one of the rare metals which has a high melting point than tungsten but it is easier to be processed. It is mainly used for high-temperature furnace parts, lighting, and electron tube. Using its characteristics:
High melting point
It has the fifth-highest melting point among metals. It has a low thermal expansion coefficient and extremely high shape stability even under high-temperature environments.
Large electric resistance
We offer it as a heater for high-temperature furnaces and electrodes for lighting due to the large electric resistance of the material.
Easy workability
With relatively easy workability among high melting point metals, it can be applied for complex shapes such as boxes and meshes.
Molybdenum is an indispensable metal in various applications: ribbon and wire in the field of lighting; and semiconductor substrates, glass melting electrodes, heaters and reflectors in high-temperature furnaces, and sputtering targets as wiring materials for solar cells and flat panels in the field of power electronics.
The material is also often used as an additive for steel materials. Using its characteristics – high melting point, excellent mechanical features, relatively easy workability compared to tungsten, etc. – it is an Indispensable metal in various applications: ribbon and wire in the field of lighting; and semiconductor substrates, glass melting electrodes, heaters, and reflectors in high-temperature furnaces, and sputtering targets as wiring materials for solar cells and flat panels in the field of power electronics.
We can provide information of usage and cooperation in designing and full line-up production for a special process that meets each customer’s needs based on the considerable experience we have accumulated in tungsten and molybdenum processing.

Product Selection Guide for
Molybdenum Wire, Rods, & Sheets
| Type | Description | Application | Non-Sag | Shock Resistance / Quake Proof | Machinability | Wear Resistance |
|---|---|---|---|---|---|---|
| MOP | The most common pure material with high melting point, high temperature strength, good thermal conductivity, low thermal expansion coefficient and excellent workability. | Structural materials, Heaters, Bolts, Nuts | Not very good | Good | Very Good | Very Good |
| MOS | General molybdenum materials may cause pitch irregularities when grids are formed with high-speed coil winders. For MOS type, we improved coiling performance and working range by adjusting components from the raw material stage. | Grids, Mandrels, Anchor | Good | Good | Very Good | Good |
| 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 better than pure molybdenum. | Supports, Heaters, Bolts, Nuts, Supporting shafts for X-ray tubes | Very Good | Very Good | Very Good | Good |
