Our investigations ferrotungsten now to stabilize the main market as a whole, some businesses offer rose slightly, mostly iron with tungsten concentrate production factory was up, not much increase in demand, market transactions in general, most of the manufacturers price adjustment ferrotungsten underpowered.
Now that tungsten concentrate prices continued to firm, tungsten, iron ore production cost is very high, and the production of tungsten, tungsten scrap iron and ferro-tungsten concentrate production use is very close, so many manufacturers two kinds can be used, while purchasing, so look ferrotungsten market price in chaos, the difference between the high price 10,000 yuan / ton. It is understood that the waste produced by 70 Tungsten Tungsten is currently focused on the mainstream market quotations 19.5-20 yuan / ton, 70 tungsten concentrate production of iron mainstream market concentrated in 21-21.5 yuan / ton between.
Today ITIA August tungsten carbide inserts guide price has been announced for the flat, we analyze expected if Minmetals August guide price is unchanged, then the tungsten iron and other products will be slightly high quote or callback, and gradually close to the actual transaction price.
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.
