Product Description
Tungsten Alloy Bucking Bars are high-density tools used in aviation, aerospace, automotive, and heavy machinery industries to absorb impact and reduce vibration when driving rivets or performing hammering tasks. Their high-density composition (up to 18.5 g/cm³) provides superior impact absorption while minimizing operator fatigue and reducing repetitive stress injuries.
With an optimized W-Ni-Cu or W-Ni-Fe composition, these bucking bars provide excellent strength, wear resistance, and vibration reduction, making them essential for precision riveting applications.
Features & Properties
✔ High Density – Up to 18.5 g/cm³, reducing rebound & vibration
✔ Vibration Dampening – Minimizes impact stress on hands & wrists
✔ Wear & Corrosion Resistance – Durable for long-term use
✔ Non-Magnetic (W-Ni-Cu Alloy) – Ideal for MRI-safe environments
✔ Customizable Shapes & Sizes – Manufactured to customer specifications
