Tungsten belongs to rare metal and also is one of important strategic materials. Many buyers buy tungsten to be used in industry and tungsten is widely applied in industry.

Tungsten was known as “scheelite” in ancient times and in 1783, tungsten was named by one Spanish. The content of molybdenum in the earth's crust is 0.001%. 20 minerals have been found that contain tungsten. Tungsten deposits are generally came into being with the granitic magma activity.

After smelting, tungsten is one silvery white and glossy metal. The melting point of tungsten is very high and the hardness of tungsten is very high. Tungsten is rare metal with high melting point. Tungsten also is silvery white metal. The appearance of tungsten is similar to that of steel. Tungsten has high melting point, very low vapor pressure and small evaporation rate. In addition, the chemical properties of tungsten is very stable. At room temperature, tungsten can not react with air and water and tungsten is insoluble in hydrochloric acid, sulfuric acid, nitric acid and alkali solution.

Most of tungsten is used to make special steels. Tungsten and molybdenum manufacturer-Zhengzhou Sanhui Co., Ltd provides tungsten bar, tungsten boat and other tungsten products. Most applied high speed steel contains 9% to 24% of tungsten. High speed steel still has high hardness and excellent abrasion performance at 600℃-650℃.

Steels which contain tungsten are used to make all kinds of tools, like drill, milling cutter, wire drawing die, female die, male die, pneumatic tools and other elements.
