Product Description

Tungsten Alloy (Tungsten Heavy Alloy) Main Application: For making rotors of dynamic intertial materials, the stabilizers of aircraft wings, shielding materials for radioactive materials, containers in hospitals and for radioactive isotope (Cobalt 60), and for material of armor piercing bullets and moulds, etc.Tungsten Alloy Advantages:-High density-Excellent mechanical properties such as high vibration-damping capacity and high Young's modulus.-Excellent radiation-shielding property-High thermal conductivity with low thermal expansion coefficient-Higher high-temperature strength and thermal shock resistance-High oxidation resistance and corrosion resistance**We supply this material as per customerized sizes and properties.Tungsten Alloy Specifications:
