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.

Extensive use of powder metallurgy production methods to produce molybdenum disk products
Molybdenum is a high temperature material, is widely used in modern industry, but its price is higher, in order to reduce costs, and now widely produced by powder metallurgy method to produce molybdenum products, molybdenum crucible is one of them, this article
sandblasted tungsten target the molybdenum combination of repression crucible mold design. Parts and die design features molybdenum crucible shape and size. Which is
copper molybdenum by wall parts and a lower tapered tube composed of two parts, and the tube wall thickness ratio of the height close to the manual pressing is not easy to ensure uniform density compacts, and prone to cracking. After repeated in the production process adjustment, find the following ideal combination of manual mold design.
