Tungsten heavy alloy is one kind of alloy, which is a class of matrix tungsten (W content of 85-99%), and add a Ni, Cu, Co, Mo, Cr and other elements. It is divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other major series by alloy composition characteristics and application. The density is about 16 .5-19.0g/cm3, called heavy alloy by the World.
It also has a series of excellent features:
High density: 16.5-18.75g/cm3;
High strength: tensile strength of 700-1000Mpa;
Can absorb rays: 30-40% higher than the lead ;
Thermal conductivitycoefficient: five times for the die steel;
Thermal expansion coefficient is small: only 1/2-1/3 of iron or steel;
Good conductive properties and good weldability and workability.
In view of so many excellent features,It is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation,
medical and other industries.
