ASTM B 777 Tungsten Heavy Alloy Sintering Parts
Introduction
The density of tungsten heavy alloy is very high. Its density is twice of steel. It is massively applied to balancing weight mold, counterweight, and high-temperature molds.
Tungsten heavy alloy has low thermal coefficient but it has high absorption ability and high-energy rays. It also can also be made into a protective shield and high-energy rays as parts of military defense.
Feature
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
