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 prices stable and weak, molybdenum products continue to be weak
Raw tungsten ore prices stable and weak, short-term tungsten mainstream or stabilize, individual product narrow adjustment; molybdenum products continue to run the disadvantaged, limited market demand, turnover difficult.
Tungsten market: raw tungsten ore prices stable and weak, the current domestic 60 degrees above the minimum purchase price wolframite concentrate on 1.88 yuan / kWh nearby; lack of sodium tungstate high transaction support, and the stock supply is tight, tungsten carbide powder market demand weakness in the short term or the continuation of "there is no market price" situation, scrap tungsten steel shipments enthusiasm high regard, the actual turnover performance in general. We expect short-term tungstenmolybdenum plating, adjust individual products within a narrow range.
Molybdenum market: The current market trend is relatively good performance of the previous month, the main product price fluctuations in the market slowdown. Miners keep watching the main signs of low turnover decreased. Mills tender prices, some manufacturers ofMolybdenum tubel and price shipping, but the quotation of prices stability. Other molybdenum-based products continue to run the disadvantaged, limited market demand, turnover difficul
