The important role and application of tungsten
Tungsten hardness is widely used, made of tungsten carbide carbide, has higher hardness and wear resistance, but also can withstand higher temperature, so if the use of tungsten carbide carbide made of cutting tool, its cutting speed and effect are much better than ordinary alloy.
But these applications is only part of tungsten can be applied, it can be widely used to make guns, penetrator, drill bit, superhard mould and so on machinery, can also be involved in mining, metallurgy, construction, transportation, electronics, chemical industry, light industry and aerospace, and other important areas, so it has a very wide range of USES, don't lose importance in rare earths.
Tungsten is a very important strategic resource, because it is in the position in each industry is very prominent, as long as the materials to join in some tungsten, can greatly improve the performance of the material, not only for some of the people's livelihood is very broad field of application, and in the military and aerospace and other fields, also play a very active role.
It is such a kind of natural resources, China's reserves in the world is relatively high, more than half. According to the data released by the US Geological Survey, by 2018, the world's proven reserves of tungsten resources are 3.3 million tons, of which China's reserves are as high as 1.9 million tons, accounting for about 58% of the world's reserves. In second place is Canada with 290,000 tons, followed by Russia with 250,000 tons and the United States with only 140,000 tons, so the United States has less than one thirteenth of China's reserves.
