Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.

Resistance welding electrode:
a combination of the advantages of tungsten wire and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, easy machining, and has features such as sweating Coolers, because of its high hardness of tungsten , melting point, anti-adhesion characteristics, are often used to make a certain wear resistance, high temperature welding, welding electrode.
