A tungsten kinetic energy penetrator (also known as a KE weapon) is a type of ammunition that, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target.

The term can apply to any type of armor-piercing shot but typically refers to a modern type of armor piercing weapon, the armor-piercing fin-stabilized discarding sabot (APFSDS), a type of long-rod penetrator (LRP), and not to small arms bullets.

The 'Fin' round travels at around 975 m/s (3200 ft/s), resulting in the generation of three and a half tones of force when it comes in contact with a weighted and/or fixed object. Energy, and therefore speed, inevitably decreases during flight, however it is still very deadly at ranges up to six kilometers.

The opposite technique to tungsten kinetic energy penetrator uses chemical energy penetrators. There are two types of these shells in use: high explosive anti-tank (HEAT) and high explosive squash head (HESH). They have been widely used against armor in the past and still have a role but are less effective against modern composite armor such as Chobham as used on main battle tanks today.

The principle of the tungsten kinetic energy penetrator is that it uses its kinetic energy, which is a function of mass and velocity, to force its way through armor. The modern KE weapon maximizes KE and minimizes the area over which it is delivered by:
being fired with a very high muzzle velocity
concentrating the force in a small impact area while still retaining a relatively large mass
maximizing the mass of whatever (albeit small) volume is occupied by the projectile—that is, using the densest metals practical, which is one of the reasons depleted uranium is often used.

Tungsten kinetic energy penetrator has led to the current designs that resemble a long metal arrow.Concentration of force into a smaller area was attained by replacing the single metal (usually steel) shot with a composite shot using two metals, a heavy core (based on tungsten) inside a lighter metal outer shell. These designs were known as Armour Piercing Composite Rigid (APCR). On impact, the core had a much more concentrated effect than plain metal shot of the same weight and size.To maximize the amount of kinetic energy released on the target, the penetrator must be made of a dense material, such as tungsten carbide or depleted uranium (DU) alloy (Staballoy).

The hardness of the penetrator is of less importance, but is still a factor as abrasion is a major component of the penetrator defeat mechanism.A common misconception is that, during impact, fractures along these bands cause the tip of the penetrator to continuously shed material, maintaining the tip's conical shape, whereas other materials such as unjacketed tungsten tend to deform into a less effective rounded profile, an effect called "mushrooming". Actually, the formation of adiabatic shear bands means that the sides of the "mushroom" tend to break away earlier, leading to a smaller head on impact, though it will still be significantly "mushroomed".

Tests have shown that the hole bored by a DU projectile is of a narrower diameter than for a similar tungsten projectile.That is one of the reasons why tungsten kinetic energy penetrator is better than the DU tungsten kinetic energy penetrator is.

Military tungsten alloy swaging rod is increasingly adopted in tungsten alloy defense as the raw material to make parts of military products, such as bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads, bulletproof vehicles, tank panzers, cannons, firearms, etc. A major use for tungsten heavy alloy is in kinetic energy penetrators, where they are in direct competition with depleted uranium (DU). Recent investigations conducted at the Army Research Laboratory show that DU’s superior properties resulted from its ability to localize shear during ballistic penetration events.

Military tungsten alloy swaging rod is produced by pressing and sintering into billets, which are worked by rolling or swaging into rod. Smaller sizes are produced by subsequent drawing. Tungsten rod is produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm. A center less-ground finish can also be furnished. Specific lengths and special fabrications can be supplied upon request.

Tungsten alloy cylinder is progressively adopted since the raw substance to create components of army products, which include bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads,bulletproof vehicles, tank panzers, cannons, firearms, etc.

A principal use for tungsten alloy cylinder is in kinetic vitality penetrators, in which they are in instant rivalry with depleted uranium (DU). latest investigations executed in the Army review Laboratory show that DU's excellent components resulted from its ability to localize shear all through ballistic penetration events. Therefore, it absolutely was argued that if localized shear could possibly be imparted to tungsten heavy alloys, these alloys would exhibit penetration ability matching that of depleted uranium (which experienced turn out to be an environmental problem).

In purchase to decrease the adoption of environmental hazardous products all through the army field, tungsten associated options are utilized like a nontoxic substitute for guide and depleted uranium in bullet and shot. High-density metals which include tungsten are now broadly employed; the intention will be to create functional, increased density, non-toxic arms projectiles with controlled result behavior. The different components of tungsten alloy render it probably the most perfect counterweight materials, much extra than at current outlined on our website. Owing to its terrific hardness and resistance to increased temperature, tungsten may be adopted in army defense progressively today.

Main army appliance: tungsten alloy bullet, shrapnel head, balanced ball for missile and plane, core for armor-piercing bullet measurement, kinetic vitality penetrators, armor and shells, grenade,rocket components.

Transient high heat loads simulations by using the electron beam facility have been performed on two tungsten heavy alloy swaging rod grades at several power loads with a pulse duration of 5 ms. The cracking patterns of the two tungsten heavy alloy swaging rod grades are quite similar. All cracks occurred along the grain boundary and located across the loaded area. The cracks can be distinguished with two levels, major cracks with larger crack width but lower crack density and microcracks with smaller crack width but higher crack density. The higher the deformation level of tungsten heavy alloy swaging rod and heat loading power density, the smaller the major crack density will be, but there is no obvious difference in the microcracks pattern. No melting occurred for both tungsten heavy alloy swaging rod grades after transient heat loading at power density of 0.88 GW m−2.

Tungsten alloy armor piercing projectile which is made of tungsten heavy alloy swaging rod comprising a high density penetrator core with a tapered front end and a multi-part outer case in partial contact with the core. This kind of tungsten alloy armor piercing projectile is made from tungsten heavy alloy swaging rod and will not penetrate because the multi-part jointed case is not as strong as a single-piece, monolithic case. Also, since the hard core is loose and not bonded to the case, then the core can not provide additional structural support. In addition, the tungsten alloy armor piercing projectile does not have the ability to either explosively damage the target after penetration, or take data from an instrumentation package during or after penetration.

Tungsten alloy armor piercing projectile comprising an axial core, a continuous strip of metallic glass wound about said core, and bonding means for joining the adjacent laminated surfaces. Tungsten heavy alloy swaging rod describes an outer case with a hole at its tip. This "hollow-point" design results in radial expansion of the jacket into "petals" as the tungsten alloy armor piercing projectile travels through the target. Such "flowering" of the case upon impact severely limits the depth of penetration into hardened targets.

Tungsten alloy armor piercing projectile comprising a heavy metal core and a segmented sabot with both right-handed and left-handed threads that separates from the core after exiting the gun's nozzle. This tungsten alloy armor piercing projectile will not penetrate deeply because the nose end is made of a brittle heavy metal alloy, rather than high-strength steel. Also, this tungsten alloy armor piercing projectile requires the use of a discarding sabot carrier.

A few years ago, people just have a general understanding of tungsten metal, but didn't focus on its value. With the development of science and technology, people began to realize that it is the magnetic material which is hard to be replaced, then people connect tungsten metal with value. Al last, tungsten metal became popolar in the market.

Unlike oil, pork,steel, tungsten metal is not often seen in our daily life and it has a sense of mistery. The value of small metals like tungsten metal is revealed with the development of science and technology. The more advanced of science, the more requiements for material. The requirements for airplanes in the past is just the ability of high and fast flying. Now we need anti-radar radiation to be used for airplanes. These requirements can not be meeted by ordaniry materials except rare materials. Nowadays, we are advocate innovation of science and technology, high-tech industry is developping very fast, so more and more small metals will be excavated.

Tungsten weights are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard. Tungsten weights are harder than steel and extremely dense, tungsten being on average 30 percent smaller than its lead counterpart.
Tungsten weights are smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. Tungsten is also used in the production of other fishing applications, such as tungsten-carbide line cutters and tungsten powder coating for fishing lines.

A fishing sinker or plummet is a weight used to force a lure or bait to increase its rate of sink, anchoring ability, and/or casting distance. Fishing sinkers may be as small as 1/32 of an ounce for applications in shallow water, even smaller for fly fishing applications, or as large as several pounds or considerably more for deep sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications. Environmental concerns surround the usage of most fishing sinker material.

A jig is a type of fishing lure that usually consisting of a lead sinker with a hook molded into it and usually covered by a soft body to attract fish. However, recently, tungsten alloy fishing weights ( fishing sinkers) is becoming more and more popular among angles because it has the features of high density, small volume, and environmental friendly, and has been taking place of the lead sinker. Jigs are intended to create a jerky, vertical motion, as opposed to spinnerbaits which move through the water horizontally. The jig is very versatile and can be used in both salt water as well as fresh water. Many species are attracted to the lure which has made it popular amongst anglers for years.

The fishing sinker/ weight is made by rare metal - Tungsten, it is an ideal substitute of the lead fishing sinker. It's strong adhesive, semi-solid state, soft for a long term. Tungsten Heavy Alloys concentrate maximum weight in the smallest possible space. They are more often to be used as counterweight in sporting field, such as tungsten alloy fishing sinkers, golf weights, etc.

Advantages of tungsten  
1. Heat resistance
The melting point of tungsten is 3380 degrees Celsius.
And the melting point of iron is only about 1500 degrees Celsius

2. Hard
When tungsten combines with carbon, t will become very hard. The hardness is close to the diamond.

3. High density
The density of tungsten is almost the same with gold.

A rocket engine or simply "rocket" is a jet engine that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.

Rocket engines produce thrust by the expulsion of a high-speed fluid exhaust. This fluid is nearly always a gas which is created by high pressure (10-200 bar) combustion of solid or liquid propellants, consisting of fuel and oxidiser components, within a combustion chamber.

Owning to its superior wearing resistance, high melting point, low vapor point and strange hardness, tungsten alloy ignition tubes  are increasingly used for rocket engines.

In rockets, temperatures employed are very often far higher than the melting point of the nozzle and combustion chamber materials, two exceptions are graphite and tungsten (~1200 K for copper) It is important that these materials be prevented from combusting, melting or vaporizing to the point of failure. So they need tungsten alloy ignition tubes.
