Frequently Asked Questions
What's the density of tungsten alloy balls?
13.5–18.2 g/cm³ depending on the W-Ni-Fe or W-Ni-Cu composition. Standard mechanical properties: hardness HRC > 22, tensile strength > 900 MPa and elongation > 10%, with diameters available from 0.5 to 25.0 mm.
What sizes and tolerances are available?
Standard diameter range is 0.5–25.0 mm. As-sintered dimensional tolerance follows our MIM norm of ±0.3–0.5%; tighter tolerances and smoother surfaces are achievable by grinding and polishing when the application requires it, e.g. for valve or bearing use.
What are tungsten alloy balls typically used for?
Mainly counterweights, hunting shots and prefabricated fragments, plus general industrial uses that need high mass in a small volume. Compared with lead, tungsten alloy offers about 1.7× the density with no lead-toxicity concerns, and it withstands far higher temperatures.
