Tungsten Alloy Bucking Bar

I know a kind of tungsten alloy products is widely used for aircraft, now i would like to show it as follows:

Tungsten Heavy Alloy bucking bars are denser than steel, resulting in a bucking bar of the same weight but half the size. Bucking bars are used in rivet setting to upset the shank of the rivet. Tungsten Heavy Alloy bucking bars reduce the recoil when reflecting the impact back to the rivet shank.

To be continuted....
