What is the density of pure tungsten and what kind of material is it?

Pure tungsten is a hard metal from steel gray to tin white, and very pure tungsten can be sawed (pure tungsten is very brittle and difficult to process). The processing methods of tungsten include forging, stretching and impact. The melting point of tungsten in all metals is relatively high, 3422 ° C, the vapor pressure is low, and the tensile strength is high (1650 ° C). Its anti-corrosion performance is very good, and most inorganic acids have little corrosion on it. A protective oxide layer is formed on its surface in the air, but it will be completely oxidized at high temperature. A small amount of tungsten can greatly increase the hardness of steel.

Tungsten has high melting point, high temperature strength, creep resistance, thermal conductivity, electrical conductivity and electron emission properties, high specific gravity, low expansion coefficient and low metal vapor pressure.
