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.

Molybdenum Disulfide Is Used in Machinery Equipment as Lubricants

When machinery equipment is in motion, friction and wear are almost inevitable on the surfaces between relatively moving parts. The use of lubricants is an effective technical measure to control friction, reduce wear, and maintain the original accuracy of machinery and equipment.

Reasonable selection of lubricating materials can control the friction of the two moving surfaces, slow down the wear and protect them from damage. The surface film formed by the solid lubricant of molybdenum disulfide (MoS2) has this function. 

MoS2 is the main component of molybdenite, which is a black solid powder with metallic luster. It is a very important solid lubricant, especially suitable for high temperature and high pressure. The powder has the advantages of good dispersibility and non-sticking. It can be added to various greases to form a non-sticky colloidal state, which can increase the lubricity and extreme pressure of the grease. It is also suitable for high-temperature, high-pressure, high-speed and high-load mechanical working conditions to extend the life of the equipment.

Place the solid lubrication on the surfaces of the two friction pairs of machinery equipment, and rely on the mechanical action between their friction surfaces to form a layer of molybdenum disulfide surface film with a high degree of adhesion attached to the solid surface, which can reduce or eliminate the direct contact between the two surfaces, reduce the friction and wear of the moving pair surface in the mechanical equipment, and extend the service life of the equipment.

The special MoS2 for coatings provided by Chinatungsten Online has a finer particle size, reaching sub-micron level, more uniform distribution, more concentrated particle size, and has good dispersibility and surface activity, which is suitable for uniform coverage on the surface of the grinding wheel.
