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 scrap prices continue steady wait
Tungsten wire scrap prices continue to safeguard stability. Current domestic waste tungsten blade purchase price excluding tax mainstream concentrated in 170-172 yuan / kg, imported blade 180-182 yuan / kg, scrap tungsten drill 196-198 yuan / kg. Pure tungsten scrap 210-215 yuan / kg. Grinding material W ≥ 70% ,1.85-1 .95 yuan / kWh; 50% <W <70% ,1.65-1 .85 yuan / kWh; 30% <W <50% ,1.45-1 .6 yuan / kWh; 10% <W < 30% 1.05 - 1.4 yuan / kWh.
Tungsten City market is still vulnerable to run, scrap tungsten sluggish market demand, the downstream waiting to see atmosphere, the overall turnover was light, the current business offer mostly remained stable, no significant price cuts will. If no further significant decline tungsten, tungsten scrap market is short-term and more will continue steady run.
International market, the overseas tungsten City a steady rise. 21 evening MB Ferrotungsten Rotterdam offer 48-49 USD / kg tungsten, up 0.2 U.S. dollars; quoted in Hong Kong 53-55 USD / kg tungsten, steady; paratungstate European price remained at 410-425 U.S. dollars / metric ton, quoted in Hong Kong 433 - $ 455 / metric ton, steady.
Tungsten ore market volume was light, many businesses wait
Core Tip: tungsten scrap prices continue to firm, but exercise alone more thinly traded; molybdenum market stalemate situation slightly thick, low-cost procurement of raw materials sweaty, molybdenum and stabilize the main; sources of market tight cash resources, vanadium market more price have a larger adjustment phenomenon; scrap titanium sponge titanium and titanium market is affected by the impact of sluggish operation difficult; ferrosilicon prices steady upward, but the steel is not fully launched the tender; currently silico-manganese market is still mainly stable, offer a more stable ; high chrome market still stable, manufacturers offer no noticeable recent fluctuations.
Tungsten Market: tungsten ore market volume was light, many businesses wait and see, ask for more cash settlement deal, Minmetals orders coming down in August, investors or weak stability maintenance. Affected by the raw materials market continued to weaken, tungsten, iron price is slightly loose, the market price remained chaotic, deserted downstream demand, the overall market transactions in general. Tungsten scrap prices continue to firm, but exercise alone more thinly traded, more customers choose to watch, short-term or continuing maintenance of stability.
molybdenum plating Market: Some manufacturers tentative to raise prices, timely approach intermediate traders to cover short positions. Market stalemate situation slightly thick, low-cost procurement of raw materials difficult, to stabilize the main molybdenum deep processing market still no significant improvement in the relative concentration of the tender mills, such as increased demand outlook, expected short-term molybdenum market or still relatively strong.
