Hubei Fotma Machinery Co.Ltd established in 2004 as a combined group engaged into manufacturing and exporting of Non-Ferrous Metals, Agricultural Machinery and Instruction Machinery etc. In 2005, our factory established in Zigong, Sichuan P.R., which is a professional manufacturer of cemented carbide products and finished machining for the tungsten & molybdenum products. We mainly focus on cemented carbide products, and the tungsten & molybdenum and other products as the salutary complementarities......
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
