Molybdenum

Molybdenum 

Molybdenum is a refractory metal with unique mechanical and chemical properties. It has a high melting point (2620°C) and boiling point (5,560°C). This high strength, tough, hard metal has excellent thermal conductivity, low heat resistance, and a low degree of thermal expansion. Molybdenum’s unique properties give rise to processes and applications in electronics, aerospace, nuclear, and metalworking industries, which would not be possible with many more common metals and alloys.

ARS can provide molybdenum metal powders and molybdenum semi-finished and finished products with high quality and competitive prices. Below are some of our standard molybdenum products. If you require some custom products, please contact us.

Applications of Molybdenum

1. High-temperature applications including furnace parts, lighting components, and electrical contacts.

2. Commonly added to high strength steel alloys.

3. Used in the production of molten zinc

Applications of Molybdenum Rod, Sheet, Plate

1. In the missile industry, molybdenum is used for: nose cones, high-temperature structural parts, nozzles, leading edges of control surfaces, support vanes, re-entry cones, and heat radiation shields.

2. In electronics, molybdenum is used for: cathodes, magnetron end hats, x-ray tube components, filaments, and glass-to-metal seals.3. In high-temperature applications, molybdenum is used for: furnace windings, structural furnace members, and containers for components exposed to high temperatures.

Applications of Molybdenum Precision Cut Wire

Molybdenum wire is widely used to construct power tube grids and support structures requiring high-temperature strength, low vapor pressure, and low thermal expansion. Molybdenum wire (and rod) is also used in high-temperature vacuum and hydrogen atmosphere furnaces to form resistance heating elements. Molybdenum wire may also be used as a heat sink and support for tungsten lamp filaments in lighting applications.
