China's tungsten products industry status
As an important non-renewable scarce resource, tungsten has been listed as an important strategic metal in the world.
The application field of cemented carbide depends on its specific properties, mainly affected by the size of tungsten carbide powder size (grain size) and binder content. When the cemented phase content of cemented carbide remains unchanged, the finer the grain size of tungsten carbide, the higher the hardness of cemented carbide will be, especially when the grain size of tungsten carbide powder is less than 0.5 micron, the hardness and bending strength of cemented carbide will be greatly improved. The larger the grain size of tungsten carbide, the higher the fracture toughness of cemented carbide, especially when the grain size of tungsten carbide powder is higher than 6.0 micron, the cemented carbide will have good fracture toughness, thermal fatigue resistance and impact toughness.
After decades of development, China's tungsten products industry gradually mature competition, market competition is relatively full. However, the industrial concentration ratio is still low, and the situation of "large, scattered and small" of tungsten products enterprises still exists. In terms of production capacity and product structure, cheap products, high-end products, exports to early, intermediate tungsten smelting low added value products of the pattern is still not changed, especially the deep processing of tungsten products compared with large foreign tungsten products enterprises still have certain gap, high performance, high precision of high-grade carbide still needs a large number of imported from abroad.
