High Density Tungsten bucking bar from china manufacturer
Material grades:90,92.5,95,97WNiFe,WNiCu alloy
Tungsten bucking bar are placed behind work surfaces to provide a backing member in applying impact
fasteners and including intermitted tool head and handle parts with a low-recoil impact-absorbing spacer
provided there between to take shock loads in compression and shear.
A rivet gun is a type of tool used to drive rivets; nearly all rivet guns are pneumatically powered.
Bucking bars are used on the backside of a metal rivet gun to counter the force of the hammering and to
create bucktail. Bucking bar also can be used to absorb the force of rivet guns, reducing the vibration of bucking.
Tungsten bucking bar used to form buck tails on rivet guns. And bucking bars come in many different shapes
and sizes, and they are normally made from alloy steel similar to tool steel. The particular shape to be used depends
upon the location and accessibility of the rivet gun to be driven.
The size and weight of tungsten bucking bars depend on the size and alloy of the rivet gun to be driven. Under
certain circumstances, and for specific rivet installations, specially designed bucking bars can be manufactured.
At XIAMET , all of our Tungsten bucking bars are made of 90+% W tungsten heavy alloy products. With the advantage
of being more than twice as dense as steel, tungsten bucking bars are the best choices for riveting, especially in the
confined spaces. With suitable tungsten bucking bars, you will make the task easier and riveting better, meaning less
rivets to drill out.
