Molybdenum Pin for Sapphire Growth Furnace and Electric Light Source Parts

How do you describe molybdenum pin? 

Molybdenum rods are rods with a diameter larger than 0.020 inch, according to standards such as ASTM B387 and ASTM F289, while in China, they feature straight lines and diameters above 0.4mm. Some rods can be able to be machined into pins, but not all rods can be called pins. For straight molybdenum wires with diameters above 0.05mm and are cut into certain lengths, they are also called pins or needles. 

Molybdenum pins are made of pure molybdenum material with good performance at high temperature because of high melting point, high strength, high hardness, low resistivity, small expansion coefficient and corrosion resistance. As the material is easy to oxide when the temperature is higher than 400 ℃, the product should be stored in a dry, ventilated, acid-alkali-free atmosphere to prevent oxidation. If they are kept in store for a very long time, its package should be in vacuum.  

In addition to the straight moly pins, one of their ends can be machined into tips with specific dimensions with tolerance. which type to be chosen depends on the applications of users. In that case, drawings should be provided for evaluation. 

Thanks to the advantages of the material, moly pins now are widely used as vacuum devices, high-temperature furnace heating devices, sapphire growth furnace, vacuum furnace, rare earth smelting furnace, glass smelting furnace, quartz smelting furnace, and electric light source parts, etc., and their applications in lighting, new energy, metallurgy, machinery, electronics, military industry and other fields have been rapidly expanded.

Molybdenum pins are generally immediately available in most volumes, including bulk quantities. Chinatungsten Online can produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. Kindly feel free to contact us if you have got the inquiry.
