Tungsten Heavy Alloy

Tungsten Weights, Tungsten Bullet Weight, Tungsten Bullet Sinker, Fishing Sinkers

Tungsten heavy alloy (WHA) is generally fabricated from WNiFe, WNiCu, or WNiCuFe with powder metallurgy technology. According to different applications and working environment, the tungsten content of WHA is about 79%W to 97%W, with the density ranging from 15.00g/cm3 to 18.10g/cm3. Some rare metals are accessible to enhance parts of the alloy's properties, like hardness, tensile strength, yield strength, and elongation. WHA is widely applicable in fields like aviation, medical, military, and sports.

Features
Tungsten heavy alloy (WHA) is distinguished for: high density, high tensile strength, good wear resistance, good X-ray & γ-ray absorption ability, good electrical & thermal conductivity, and good machinability.

Applications
Gyroscope, container for radioactive source, leaves for MLC, shielding parts for nuclear power instrument, weight stack for Golf clubs & fishing rod
