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.

Now, the tungsten alloy is gradually being used for military products, including bullets,armor and artillery shells, grenades, rifles, bullet head, bullets, bullet proof car, tanks,artillery, raw material like creating components in. The main purpose of tungsten alloyis in the kinetic energy penetrators, they will in the depleted uranium (DU) computing instant competition.

Tungsten is a naturally occurring metal. Tungsten can be used in pure form or othermetal and alloy. Tungsten alloy is often strong, flexible, abrasion resistance. Tungsten and its alloy are used for a variety of commercial products, including the bulb's filament, X ray tube, welding, grinding wheel, ceramic pigment and flame retardant.

Many countries have been used for many years, because of tungsten and tungsten alloy ammunition to its high density and the resulting penetrator penetrating. If there is a tungsten alloy

Gold in the army's "green bullets"? "Green bullets" refers to the ammunition lead-free,to provide environmental protection by the army to provide ammunition for customers.Do not use "green" or lead-free bullets military tungsten alloy. "Green bullets" usually contains mixed together, both nylon or tin and tungsten. On the other hand, tungstenalloy, containing other metals, such as nickel, cobalt, iron or copper, which is heated to high temperature materials allowed together. Although the "green" the bullet had been in training

Army facilities operation uses a limited number, it has not been used on the battlefield.

Since its launch, more than 900000 of the "green" training ammunition has been usedin American. It relies on tungsten and nylon, mixture of tungsten and tin. This makesthe bullet has density and emission performance of the same in the case of withoutlead. Tungsten is non-toxic products, high density tungsten alloy is mainly used formetal, composite materials in military field.

High density tungsten alloy is more and more used in the military defense parts production, such as bullets, armor and artillery shells, bombs, grenades, titles,shotgun bullets, bullet proof car, tank armor, guns, guns and national defense etc..The main purpose of tungsten alloy penetrators in kinetic energy is, depleted uranium(DU) calculation in direct competition.

A significant mass of tungsten has been used for the production of military trainingfacilities, as an alternative to the use of lead shot 5.56 mm ammunition. Tungstenquality, for a fixed target / fixed firing position has produced the desired soil containingtungsten concentration%, in addition to the traditional lead.

Properties of tungsten alloy

Two times the density of tungsten alloy having a melting point and steel high, heavier than lead more than 50%. High density tungsten alloy than lead with greater radiation shielding and non-toxic. Tungsten alloy contribute to electrical and thermal conductivity, and good corrosion resistance. Their low expansion coefficient, highelastic modulus. Because of these unique properties of tungsten alloys are widelyused in military, balance weight, alloy rocket assembly and bullets and other heavy metals, especially the weight of aircraft and offset the gyrocompass.

Heavy metal insert is used as the core military pellet quality is high, so the tungsten alloy are widely used in military defense.

Military tungsten alloy

Powder metallurgy (P / M) military, extended from the traditional media and sintering liquid phase sintered tungsten alloy (WHA) by powder injection molding (PIM>). The navy has hired them to the third phalanx close in weapon system (CIWS) the great advantage of the world health assembly. The army intends to research will lead totungsten alloy or composite materials, as a long rod penetrator, will perform as well as, or better than, the depleted uranium (DU) penetrator. Tungsten alloy WHAs) is the best choice, is the ideal material for national defence industry, it combines the highdensity, mechanical strength, good and easy processing performance, tungsten alloy is an important material in military defense.

Method of forming forging is regular or irregular use of two or more than two moldaround the workpiece completely or partially reduce the cross-sectional area of a circular predetermined diameter rods or wire.

The forging process is the use of rotary forging machine forging and rolling metal so that the forming, combined machining technology, the plasticity of tungsten alloy rods,in the forging temperature range from 1200 ℃ to 1500 ℃ from. Metal forming process,first by the local deformation gradually expanded to the whole deformation process.

Drawing tools, but also can improve the tensile strength of tungsten alloy rod, tensile strength and prolong the service life of the tungsten alloy rod, increase the value to a large extent.

However, the drawing tools can cause serious problems, more importantly, strength and tensile strength is far better than forging low. After forging, greatly improve the tungsten alloy rod off the power and the tensile strength, improve product performance and prolong the service life and better surface quality of tungsten alloyrod. Forging technology has been widely in the foreign press die instead of drawingtools.
