Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Warhead of AGM-114 is made of tungsten alloy swaging rod.

The AGM-114 is an air-to-surface missile (ASM) developed primarily for anti-armor use. It was originally developed under the name Helicopter Launched, Fire and Forget Missile, which led to the acronym 'Hellfire' that became the missile's formal name.[2] It has multi-mission, multi-target precision-strike capability, and can be launched from multiple air, sea, and ground platforms. The Hellfire missile is the primary 100 lb-class air-to-ground precision weapon for the armed forces of the United States and many other nations, and is considered a proven tactical missile system, as it has been used in combat since the mid-1980s.

AGM-114 is a comprehensive weapon system that can be deployed from rotary- and fixed-wing aircraft, waterborne vessels and land-based systems against a variety of targets.

With the high density and high hardness of tungsten alloy swaging rod, AGM-114 can penetrate the armor and destroy the tank.

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 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 bucking bar on the shank of the rivet.

3.Find the center of the shank with the bucking 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 bucking bar steady against the shank once the center has been found, then activate the pneumatic hammer to drive the rivet home.

Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Warhead of FGM-148 is made of tungsten alloy swaging rod.

FGM-148 is a United States-made man-portable fire-and-forget anti-tank missile fielded to replace the Dragon antitank missile in US service.

FGM-148  is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top-attack flight profile against armored vehicles (attacking the top armor, which is generally thinner), but can also take a direct-attack mode for use against buildings. This missile also has the ability to engage helicopters in the direct attack mode. It can reach a peak altitude of 150 m (500 ft) in top-attack mode and 60 m in direct-fire mode. It is equipped with an imaging infrared seeker. The tandem warhead is fitted with two shaped charges: a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate base armor.

With the high density and high hardness of tungsten alloy swaging rod, FGM-148 can penetrate the armor on the top of tank and destroy the tank.

 The bucking bar includes a housing and a driven member movable with respect to the housing. The worker using the bar holds it with the driven member pressed against one end of the rivet. When blows are delivered from the hammer through the rivet to the bar, an appropriate reaction force is generated automatically by mechanisms within the bar. These mechanisms include at least a first pressure chamber and an exhaust port for releasing pressure from the pressure chamber to the atmosphere. By controlling the flow of air through the pressure chamber, the mechanisms within the bucking bar control the forces acting on the driven member during the recoil and rebound motions. Preferred control mechanisms include a second pressure chamber and a movable shuttle. The shuttle is initially biased in a preferred direction by a biasing element in the form of a coil spring. Subsequent movement of the shuttle is dependent upon the characteristics of the hammer blow. Generation of reaction force within the bucking bar is in turn dependent on the position and motion of the shuttle. Preferably, the shuttle acts as part of several valves controlling the flow of pressurized air into and out of the two pressure chambers. A piston fixed to the end of the driven member acts as part of another valve for controlling the flow of pressurized air into the first pressure chamber.
