Tungsten Alloy Counterweight Screws – Precision Balancing for High-Performance Systems

Why Tungsten?

Tungsten heavy alloy (WNiFe, WNiCu) screws provide superior weight distribution due to:

✅ Ultra-High Density (17–18.5 g/cm³) – 2.5X heavier than steel in the same size.

✅ Compact Design – Achieve precise balance without bulky components.

✅ Corrosion Resistance – Withstands harsh environments (saltwater, chemicals).

✅ Vibration Damping – Reduces harmonic resonance in rotating systems.
