According to statistics from the Peruvian Ministry of Mines and Mines, due to factors such as aging of mines, declining mining grades and strikes by miners, the production of major metals in Peru declined in 2018.
China's tungsten industry has generally maintained a stable operating situation. The output continued to grow steadily, the export remained high, the price fluctuated slightly, and the economic benefits of the company continued to improve.
Since 2018, the tungsten industry has generally maintained a stable operation.The output of major products increased steadily. From January to November, the national tungsten concentrate production was 105,000 tons (WO365%), up 2.8% year-on-year;
The powder particle size and uniformity of tungsten powder and copper powder will affect the sintering effect of tungsten-copper alloy electrode to a certain extent. The reduction of powder particle size will make the comprehensive properties of materials such as density, hardness etc.
The morphological distribution of the tungsten-copper powder sintered material is uniformly distributed on the copper substrate with tungsten as a skeleton. Due to the high melting point and high hardness of tungsten W, the ultimate tensile strength of tungsten at 1000 ° C is still 50kgf / mm2
Tungsten industry situationIn in the first three quarters of this year, China's tungsten industry generally maintained a stable operation. The output continued to grow steadily, the export remained high, the price fluctuated slightly, and the economic benefits of the company continued to improve.
The performance of stainless steel with molybdenum is better than that of other grades. It has enhanced resistance to chloride ions and contaminants, and has better pitting and crevice corrosion resistance to prevent salt and corrosion. Corrosion caused by contaminants is very useful.
Carbide indexable CNC tools are tools used in machining for machining, also called cutting tools. The generalized cutting tools include both tools and grinding tools. At the same time, "hard alloy CNC tools" include accessories such as shanks and shanks in addition to cutting blades.
