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.

August 23 was 129.9 concentrates index TCPI
August 23 tungsten carbide inserts price 132,500 yuan / ton, the price index was 129.9 (2012-8-20,102000 yuan / ton), representing the lowest point of 100 cycles (2012-8-20) raised 29.9. Our tungsten ore market turnover is expected next week will be difficult to have a big breakthrough in the overall market or continue steady weak.
Note: Cycle refers 2012-8-20 date, tungsten Index (Tungsten concentrate price index, TCPI) is the date 2012-8-20 price comparison with mainstream price formation relative number.
This week tungsten prices, demand continues to slump, business confidence. High production costs, demand remains in the doldrums, tungsten ore businesses survive in the cracks, abnormal operation carefully, the whole tungsten ore market is almost "priceless free city." Business mentality slightly differences, mainly in two ways.
The late part of the business that tungsten ore prices will remain high for two main reasons: a tungsten high production costs, which is the most significant reason, two tungsten itself rare attributes, three tungsten importance of the application of national policies or even more focus on tungsten.
Another part of the business that concentrates market continues down this is normal, if there is no demand for support, the latter may continue to fall until the market really go along with a reasonable price. Main reasons: First up is not the shortage of raw materials led so far this year are adequate overall inventory tungsten ore; two prices is not demand-driven, no actual downstream demand, the price of tungsten lack of support; three at home and abroad this year, the overall economic environment is not very good, to some extent restricted the tungsten demand; four bank loans difficult, costs increase; Fifth, some time ago, the actual purchase of tungsten ore is mainly Minmetals purchasing and storage. August 21 was 129.9 concentrates index TCPI
