This is the Ultimate Bucking bar material - you will never use steel bars again! Because of the density, you can create the best shape for your space so it's just right for getting inside the ribs and spars gaps on wings, flight controls, etc. The weight and the density of the metal make for the best rivet bucking in the industry. With tungsten-based bars, just a few taps with a 3X rivet gun and a 1/4 rivet is complete. This saves possible damage to the aircraft skin and frames due to less repeat riveting and it also saves time allowing you to move on to the next rivet.
Tungsten-based bucking bars are also ergonomically better than steel. Studies show that tungsten-based bucking bars reduce the amount of vibration the user experiences and therefore reduces the chance for white finger or carpal tunnel syndrome
