Pure Tungsten Properties

Tungsten has the highest melting point (3422C) of all the non-alloyed metals. It can keep its strength and stiffness at high temperatures. Tungsten has good thermal conductivity, excellent corrosion resistance, and lowest thermal expansion of any pure metal.

Tungsten is suitable for aerospace and high temperature uses which include electrical, heating, and welding applications. Hardness and density properties make this metal ideal for making heavy metal alloys such as copper tungsten that are used in armament, heat sinks, and high density applications.
