Tungsten resource is quite precious and rare metal resources. Tungsten industry, as one of the important material industry in the modern industry, is of great significance.
Tungsten is a kind metal with high hardness, high melting point and good strength, which are widely used in machinery, special steel, national defense and other fields. Its main application is in cemented carbide industry, which is often said the tungsten steel.Cemented carbide is referred to as the teeth of modern industry. As the important strategic resources, the powerful nations in the world pay more attention to the protection of tungsten resource. Since the 90s, our country set up the industry association and issued a number of laws, regulations and strict regulation to protect the tungsten resources.
The global tungsten resources are scarce, but in the concentrated distribution. China’s reserve accounts for 65.5% of the world with the clear advantages. Beginning in 2001, our country began to implement the mining quotas and export quota of the stungsten resources, which effectively restrain the global supply of tungsten. Combined with the foreign supply reducing year by year and the limited ability of the tungsten waste recycling, the growth speed of the tungsten supply is relatively slow.
Tungsten is mainly used in the cemented carbide, steel, alloy, chemical industry and other fields. The consumption of carbide accounts for about 50%. The production of carbide cutting tools in China accounts for about 25% of the total production of the carbide cutting tools. The consumption of the carbide cutting tools in the developed countries accounts for 65%. Our country has the broad space for the development of China cemented carbide in the future. Our country explicitly encourages the new materials containing tungsten and tungsten products to the new impetus in the document of the 12th five-year plan.
Tungsten resource has the absolute advantage of rare metals in China. With the country gradually consolidating the industry, the growth of supply will slow down gradually. However, the demand of the carbide grows fasterly in the long run. The supply of tungsten will in a tight state in the future. The tungsten carbide industry, relying on the tungsten resources of our country's absolute advantage, is bound to develop more quickly.
