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.

tungsten ore market is basically steady, business sentiment strong
Domestic tungsten ore market is basically steady, business sentiment strong, APT high firm turnover was low and trading volume has remained small. Molybdenum market remain weak consolidation state, the venue is hard to find favorable factors support, product prices fluctuate slowly.
Tungsten eletrode: domestic tungsten ore market is basically steady, business sentiment strong, APT expensive firm, but always maintaining low turnover and trading volume is small, the downstream steel demand ferrotungsten difficult aspects of a significant improvement in some areas, prices are still confused, powder slight improvement market, prices stable and inflation. We expect short-term price of tungsten mainstream stabilize, individual range-bound.
Molybdenum market: current state of molybdenum market remain weak consolidation, the venue is hard to find favorable factors support, product prices fluctuate slowly. Factory orders scarce and low profitability of foreign shipments difficult. Low prices of some products frustrated severe lower prices downstream manufacturers, sellers and more stay on the sidelines, is expected to turn for the better short-term molybdenum market there is still no sign of weakness late maintenance of stability
