Our 97WNiFe (Tungsten-Nickel-Iron) alloy balls are engineered for applications requiring maximum weight in minimal space. With a high tungsten content of 97%, these spheres offer a density of up to 18.5 g/cm roughly 1.6 times heavier than lead. They combine extreme mass with excellent mechanical strength, making them the gold standard for industrial balancing, fluid control, and radiation shielding.
Extreme Density: High specific gravity 18.25-18.55g/cm provides superior mass for precision counterweights.
High Mechanical Strength: Superior tensile strength and hardness compared to pure tungsten, preventing deformation under high pressure.
Eco-Friendly & Non-Toxic: The ideal green alternative to lead for weight and shielding applications.
Precision Surface Finish: Available in polished or precision-ground finishes with strict sphericity tolerances for high-performance valve applications.
Corrosion & Wear Resistant: Exceptional durability in harsh chemical or high-friction environments.
