The introduction of Tungsten Heavy Metal

In tungsten's raw form, it is a hard steel-gray metal that is often brittle and hard to work. If made very pure, tungsten retains its hardness (which exceeds that of many steels), and becomes malleable enough that it can be worked easily.

Tungsten heavy metal has the highest melting point and the lowest vapor pressure among all the metals, which makes it a preferred candidate for use as a high performance material in a variety of high temperature products and processes.

Tungsten heavy metal is resistant to corrosion when the humidity is below 60%. However, it must be protected at elevated temperatures. Tungsten heavy metal can oxidize in the presence of oxidizing gases at temperatures above 250°C. Despite this vulnerability, molten glass, nitrogen, inert gases, molten metals and ceramic oxides only slightly affect it.

Widely and extensively used in lighting industry, electronics, military equipment, nuclear, mechanical manufacturing, aircraft components, medical shields, and sports equipment. Tungsten Heavy metal has excellent radiation resistance, electric and thermal conductivities, corrosion resistance with high density (16.5-18.5 g/cm3) and good mechanical strength. Tungsten heavy metal also has small coefficient of expansion and large elastic modulus.
