Tungsten alloy bucking bar which is sometimes called tungsten alloy rivet buck, is used for bucking the rivets.

When you are going to buck rivets, this is just another name for setting them in place. A rivet is essentially a metal pin with a head on one end and a shank that goes through a hole between two pieces of metal. When the head is compressed against a tungsten alloy bucking bar on the shank side, the shank has no where to go and expands outward forming another head. These two heads on either side act as a fastener and hold the piece of metal tightly together.

1.Place the rivet to be bucked into a rivet hole.

2.Push the pneumatic hammer against the head of the rivet, while at the same time placing the tungsten alloy bucking bar(rivet bar) on the shank of the rivet.

3.Find the center of the shank with the tungsten alloy bucking bar(rivet bar). This does not have to be an exact science, but the closer the center can be found while pushing against the shank, the more symmetrical the expansion of the rivet shank will be.

4.Hold the tungsten alloy bucking bar(rivet bar) steady against the shank once the center has been found, then activate the pneumatic hammer to drive the rivet home.

Bucking bar is a work tool received behind work surfaces to provide a backing member in applying impact fasteners and including intermitted toolhead and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear.

Bucking bars are used on the backside of a metal rivet to counter the force of the hammering on the other side. They also can be used to absorb the force of rivet guns, reducing the vibration of bucking.

Bucking bars used to form bucktails on rivets. And come in many different shapes and sizes. They are normally made from an alloy steel similar to tool steel. The particular shape to be used depends upon the location and accessibility of the rivet to be driven.

The size and weight of the bar depend on the size and alloy of the rivet to be driven. Under certain circumstances, and for specific rivet installations, specially designed bucking bars are manufactured locally.

Bucking bars are normally made from tungsten heavy alloy. All edges are deburred and working surfaces are polished for troubles-free use. This helps to prevent marring of formed bucktails. Please notice that never hold a bucking bar in a vise unless the vise jaws are equipped with protective covers to prevent marring of the bucking bar.

Fishing beads can be as an attractor or be a component of the rig when you are fishing.

Fishing beads can be made from plastic, brass, lead, tungsten and so on. And they come in many different colors.There are also luminous beads made of plastic which glow in low light when the water you are fishing has low visibility to attract fish.

However, tungsten alloy fishing bead becomes more and more popular because of its good properties. Tungsten fishing bead is made from tungsten alloy, so some peple call tungsten alloy fishing bead as tungsten fishing bead.
