The density of tungsten heavy alloy is very high. Its density is twice of steel.It is massively applied to balancing weight mould,counterweight and high temperature moulds. Tungsten heavy alloy has low thermal coefficient but it has high absorption ability and high-energy rays.It aslo can be made into protective shield and high-energy rays as the parts of military defense.

利点：
1.High density
2.High wear-resistant
3.High thermal conductivity with low thermal expansion coefficient 
4.High vibration-damping capacity and high Young's modulus
5.High oxidation resistance and corrosion resistance
