Heavy alloy is the generic name for tungsten-based, high-density alloy and contains nickel, copper and iron as additives for homogeneous sintering. The alloy material is classified according to composition, or tungsten content (90%-96%) and the sorts of additives.
Advantages
•High density of 17-18.4Mg/m3.
•Excellent mechanical properties such as high vibrationdamping 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.
Applications
•X-ray devices both for medical and industrial use, radiation-shielding components for gamma-ray devices, andisotope containers.
•Vibrator balances for cellular phones, and flywheels.
•Boring bars and quills.
•Die parts for diecast dies, core pins and sleeves.
•Electrodes.
•Heat treatment furnace jigs .
