overview
Tungsten Heavy Alloy Balls are spherical products made from tungsten heavy alloys such as W-Ni-Fe and W-Ni-Cu. With high tungsten content and density up to 18.75 g/cm³, they provide high mass in a compact size. They are widely used for counterweights, balancing components, radiation shielding, and other applications requiring compact mass.
FANMETAL supplies tungsten alloy balls in different grades, densities, and diameters for applications requiring high density, compact weight, balance, or inertia. Standard and custom sizes are available according to drawings or application requirements.

Tungsten Heavy Alloy Grades
Tungsten heavy alloy balls are available in different tungsten contents and alloy systems. Common grades include W-Ni-Fe and W-Ni-Cu alloys with approximately 90% to 97% tungsten. Higher tungsten content generally provides higher density. ASTM B777 classifies tungsten heavy alloys into four classes based on tungsten content and density.
| Grade | Tungsten Content | Nominal Density |
|---|---|---|
| ASTM B777 Class 1 | 90% | 17.0 g/cm³ |
| ASTM B777 Class 2 | 92.5% | 17.5 g/cm³ |
| ASTM B777 Class 3 | 95% | 18.0 g/cm³ |
| ASTM B777 Class 4 | 97% | 18.5 g/cm³ |
Customization
Tungsten heavy alloy balls can be supplied in different diameters, grades, densities, and surface finishes. Custom dimensions and specifications can be produced according to customer drawings or application requirements. Please contact us with the required material grade, diameter, quantity, and tolerance.
