99.95% Pure W High-Density Tungsten Sphere
99.95% Pure W High-Density Tungsten Sphere
Pioneer New Material tungsten spheres are precision-engineered to deliver unmatched density (19.3 g/cm³) and dimensional stability. Manufactured from 99.95% pure tungsten through advanced powder metallurgy and CNC grinding processes, these spheres outperform steel, lead, and ceramic alternatives in extreme environments.
Key Advantages
✓ Extreme Density - 2.5× denser than steel, ideal for compact counterweights
✓ Thermal Stability - Maintains shape up to 2000°C in inert atmospheres
✓ Corrosion Resistance - Impervious to acids/alkalis (except HF/HNO₃ mix)
✓ Custom Configurations - Coatings (Au, TiN), laser marking, alloy blends
