Tungsten alloy armor piercing bullets are famous for their ability to penetrate target. It is mostly because large kinetic energy and their high tensile strength focused on the target. The bullets are made from the high-density tungsten alloy that is much harder than most armor. All have very hard warheads.

Tungsten alloy armor piercing bullets can be used against tanks, armored vehicles and concrete fortifications. When fired, bullets are under the high-temperature, high-pressure gas. Reach the target; it will make a pit in the surface of the armor, red out the armor and the pit bottom at the same time. At this time, although the head has been broken, missile force the powerful impact of inertia, it will continue onrush. When the impact force reaches a certain value, the fuse is triggered; it caused the explosion of the projectile charge. At this time, exploding charge will create tons of pressure per square centimeter in area, killing the crew inside the tank or destroying armored weapons.

The mining industry has one of the highest demands for tungsten carbide coated tools that have high wear-resistant, as working in a mine involves cutting through hard rock, often spanning several miles. Having tools that are resistant to wear means the company doesn’t have to replace their tools often, preventing money lost due to down times. Thus, there is a need for tungsten carbide coated tools that do not wear out easily, ensuring continued productivity for longer periods of time.

Before the use of these tungsten carbide coated tools, mining was primarily done using pick axes and shovels, to be replaced later on by tools made of steel. Where shovels relied on pure manpower to get the job done, steel tools did a better job, albeit, they were susceptible to wear.

Then came tungsten carbide tools. Since tools made of tungsten carbide are tougher and more wear-resistant, these tools are able to perform their job faster and for a longer time when compared to steel tools.

Mining companies are always on the lookout for more abrasion resistant tools beyond the usual tungsten carbide coated tools. Cemented carbide was developed by combining tungsten carbide, titanium carbide, tantalum carbide, and cobalt. This combination is even harder than regular carbine, while further improving ordinary tungsten carbine’s heat resistance ability.

Tungsten alloy armor piercing bullet relying on the kinetic energy of the projectile, penetrates armor and destroys the target. Its characteristic is high velocity, long hitting the distance and good accuracy. It used for mutilate tanks, self-propelled guns, armored vehicles, ships, aircraft, or any other armored target.

Tungsten alloy armor piercing bullet is a type of ammunition designed to penetrate armor and detonate. They are generally used against body armor, vehicle armor, tanks and other defenses, depending on the caliber of the firearms.

Shells of bullets designed for this purpose have a greatly strengthened case with a specially hardened and shaped nose and a much smaller bursting charge. Some smaller caliber tungsten alloy armor piercing shells have an inert filling, or incendiary charge in place of the HE bursting charge.

Tungsten alloy armor piercing ammunition is used to penetrate heavy hardened armored targets such as armored vehicles, concrete bunkers, tanks and other defenses. Depending on the caliber of the firearms. It is ammunition consists of a penetrator constructed of tungsten alloy or tungsten carbide, or depleted uranium, enclosed within a softer jacket, such as copper or aluminum. The product ammunition can range from rifle- and pistol-caliber rounds all the way up to tank rounds.

Rifle and pistol rounds are usually built around a penetrator of hardened steel or tungsten. Aircraft and tank rounds sometimes use a tungsten alloy core. Tungsten alloy armor piercing ammunition is a pointed mass of high-density material that is designed to retain its shape and carry the maximum possible amount of energy as deeply as possible into the target. Depleted-uranium penetrators have the advantage of being hydrophobic and self-sharpening on impact, resulting in intense heat and energy focused on a minimal area of the target's armor. Some rounds also use explosive or incendiary tips to aid in the penetration of thicker armor. High Explosive Incendiary/Armor Piercing Ammunition combines a tungsten carbide penetrator with an incendiary and explosive tip.

Rifle ammunition generally carries its hardened penetrator within a copper or cupronickel jacket, similar to the jacket that would surround lead in a conventional projectile. Upon impact on a hard target, the copper case is destroyed, but the penetrator continues its motion and penetrates the target. It's ammunition for pistols has also been developed and uses a design similar to the rifle ammunition.

The entire projectile is not normally made of the same material as the penetrator because the physical characteristics that make a good penetrator (i.e. extremely tough, hard metal) make the material equally harmful to the barrel of the gun firing the cartridge.

Tungsten alloy armor piercing shell is a type of ammunition designed to penetrate armor. From the 1860s to 1950s, a major application of armor-piercing tungsten projectiles was to defeat the thick armor carried on many warships. From the 1920s onwards, armor-piercing weapons were required for anti-tank missions.

Tungsten alloy armor piercing shell must withstand the shock of punching through armor plating. Shells designed for this purpose have a greatly strengthened case with an especially hardened and shaped nose, and a much smaller bursting charge. Some smaller-caliber AP shells have an inert filling, or incendiary charge in place of the HE bursting charge. The AP shell is now little used in naval warfare, as modern warships have little or no armor protection. The product remains the preferred round in tank warfare, as it has a greater "first-hit kill" probability than a high explosive anti-tank (HEAT) round, especially against a target with composite armor, and because of higher muzzle velocity, is also more accurate than a HEAT round.

Firstly, mix tungsten powder together with other elements, such as Ni, Fe, Cu, etc. Put them into a specially designed mold which is in heating furnace. Heat up to a certain temperature and through a certain time, we can get tungsten alloy rod.

Secondly, transfer the rod to a temporary support which supports the tungsten alloy rod is heated three quarters of an hour at about I600°C. In an electrically heated tube furnace, tungsten alloy rod is protected from oxidation at this temperature by hydrogen gas. Tungsten alloy rods are heated to about 1600°C. Then with an atmosphere of hydrogen gas in an electric furnace, tungsten alloy is rapidly passed through the swaging machine. In this operation the diameter of the rod is reduced 10 percent. Tungsten alloy rods are then re-heated in the furnace and are ready for the next pair of swaging dies which will again reduce its diameter by 10 percent.

Thirdly, machining. Tungsten alloy is so hard that it cannot be machined by sharp edge tools, but it can be brought into desire shapes by high temperature hammering or cold grinding.

Tungsten alloy defense technology in the area of thin-walled guided missiles allows bullets weighing 700 grams to hold 500 grams of effective load. The function of ejection stand off ammunition is to make a barrage out of the tungsten alloy defense, but not to markedly increase their kinetic energy. Nitrified fiber firing ammunition and a high intensity carbon steel ammunition cartridge endows the bullets with 1050metre/sec initial velocity.

Tungsten Military Application in Types of Weapons:

◆The GNU-44 Viper Strike missile, carried by armed drones, has a tungsten sleeve to produce powerful shrapnel.
◆The 130-round-per-second Phalanx anti-missile Gatling gun, deployed on U.S. and Royal Navy ships, originally used DU rounds. They were replaced with tungsten alloy, for environmental reasons.
◆120mm anti-tank rounds use tungsten military application as an alternative to DU in training. So do the 25mm anti-tank rounds, on board the M2/M3 Bradley fighting vehicle.
◆Armor-piercing .308 M993 rifle rounds.
◆The 120mm M1028 anti-personnel round, fired by the Abrams tank. It's basically a giant shotgun shell loaded with 1100 tungsten balls, each 3/8th of an inch big.

Cobalt is by far the most widely used binder metal or “cement” in cemented tungsten carbides because it most effectively wets tungsten carbide grains during liquid phase sintering. For this reason cobalt is believed to be superior to other binder metals in terms of eliminating residual porosity and achieving high strength and toughness values in sintered products. The failure of cemented carbides in corrosive environments, however, is generally due to the chemical reaction of cobalt with corrosive agents. The corrosion process involves the dissolution of the cobalt binder at exposed surfaces leaving a loosely knit skeleton of tungsten carbide grains having little structural integrity. This mechanism is often referred to as cobalt “leaching” and is typically accompanied by a flaking off of unsupported carbide grains in the affected surface areas.

Although WC + Co grades have fairly good resistance to attack by acetone, ethanol, gasoline and other organic solvents as well as by ammonia, most bases, weak acids, and tap water. Exposure to formic, hydrochloric, hydrofluoric, nitric, phosphoric, sulfuric, and other strong acids, however, can result in a relatively rapid deterioration of the binder phase. Corrosion rates are affected also by temperature, the concentration and electrical conductivity of the corrosive agent, and by other environmental factors. Alloying cobalt with chromium, molybdenum, and/or nickel can significantly improve the resistance of the binder to corrosion, but the complete substitution of nickel for cobalt has proven to be the most effective means of extending the life of cemented carbides in highly corrosive environments. WC + Ni grades and other special formulations designed to resist corrosion without compromising strength or other attributes are therefore ideal for applications such as seal rings, fluid control components, choke valves, nozzles, and bearings.
