Tungsten Alloy Bullet for Army

The Army has stopped producing so-called "green" training rounds, because of research showing that the bullets' main ingredient may be more toxic than previously thought. But that element, tungsten, is also in an array of other ammunition and munitions, as well. Which means all sorts of rockets, missiles, and anti-tank rounds may present an environmental hazard and a health risk.

Tungsten was introduced to weaponry as an alternative to depleted uranium, or DU -- itself an alleged toxin.

Tungsten Alloys is “Green Bullet” in Army

Tungsten alloys are not used in the “green” or lead-free bullet. The bullet are “green” because they are considered more environmental friendly than bullets containing lead. Green bullests typically contain tungsten that is mixed together with either nylon or tin. Tungsten alloys used in armor-piercing munitions, on the other hand, contain other metals, such as nickel, cobalt, iron, or copper, and are subjected to high temperature and pressure to bond the materials together. 

Now the green bullet has been widely used in Army installations.

What is Tungsten(3)

Tungsten has been used without ill effects as a component in US food and Drug Administration (FDA)-approved medical implants such as orthopedic hardware and tungsten coils for heart defects. Numerous countries have used tungsten and various tungsten alloy munitions for a number of years because of its high density and ability to penetrate armor. Initially, tungsten carbide was used in munitions, but newer composites such as tungsten/nickel/cobalt and tungsten/nickel/iron have superior properties.

What is Tungsten (2)

Tungsten is a naturally occuring metal. Tungsten can be used either in pure form or mixed with other metals to make alloys.
Tungsten alloys tend to be strong, and resistant to heat and wear. Tungsten and its allys are used in a variety of commercial products including loght bulb filaments, X-ray tubes, welding electrodes, grinding wheels and ceramic pigments.

What is tungsten?

Tungsten, from the Swedish tung sten meaning ‘heavy stone'; chemical symbol W, was first isolated in 1783. The heavy alloys of this hard, dense metal should not be confused with tungsten carbide, as used in cutting tools. These alloys typically contain 90 - 97 wt%, hence deriving their fundamental properties from tungsten. As a result, WHAs are becoming the materials of choice for designers and engineers who require such properties as high density, good mechanical strength and ease of machining for use in radiation shielding and collimation and above all, counterweights and ballast.

Therefore, tungsten added with Ni, Fe, Cu is very suitable matreial for counterweights. You could visit tungsten-alloy.com. for more details.

Tungsten Alloy for Sports--Fishing(1)

According to my knowledge, tungsten alloy material is widly used for sprots, some of my friends who are interest in fishing, told me that fishing sinker, which is also called fishing weight, is usually made of tungsten alloy material.
They told me that tungsten should be the most suitbale material right now for fishing, as its small capacity but heacy density, also it is very environmental-friendly.
It is very intersting for me to know such things, for me, i am also fond of fishing, in the past, i usually use lead weight, but it seems that lead is not so environmental protective,therefore, i have tried some tungsten alloy fishing weight. It feels good. If the through hold is grindered soomthful enough, the line would be protected well. Or if you would require plastic inster for them.
Here attached some photos for the weights i used:

Tungsten Alloy Bucking Bar

I know a kind of tungsten alloy products is widely used for aircraft, now i would like to show it as follows:

Tungsten Heavy Alloy bucking bars are denser than steel, resulting in a bucking bar of the same weight but half the size. Bucking bars are used in rivet setting to upset the shank of the rivet. Tungsten Heavy Alloy bucking bars reduce the recoil when reflecting the impact back to the rivet shank.

To be continuted....

Tungsten Heavy Alloy Applications & Advantages

Recently, many friends ask me about the application and advantages for tungsten heavy alloy materials, now I would like to give some tips as follows:

Tungsten heavy alloy material is a tungsten-base materials that typically contain 90 to 97 wt% W. Most commercial tungsten alloy products are two-phase structures, the principal phase being nearly pure tungsten in association with a binder phase containing the transition metals plus dissolved tungsten. Then tungsten alloy derive their fundamental properties from those of the principal tungsten phase, which provides for both high density and high elastic stiffness. It is these two properties that give rise to must applications for this family of materials.
The current uses of tungsten heavy alloy are spanning a wide range of consumer, industrial, and government applications that include:

Damping weights for computer disk drive heads
Balancing weights for ailerons in commercial aircraft, helicopter rotors, and for guided missiles
Kinetic energy penetrators for defeating heavy armor
Fragmentation warheads
Radiation shielding, radio isotope containers, and collimalion apertures for cancer therapy devices
High performance lead-free shot for waterfowl hunting
Gyroscope components
Weight distribution adjustment in sailboats and race cars.
Work as gold-plated handcraft

Many applications that require high gravimetric density for balance weights, inertial masses, or kinetic energy penetrators or high radiographic density for radiation shielding and collimaiion necessitate rather large bulk shapes. Such a requirement eliminates all but a few candidates on the basis of prohibitive cost, typically reducing the choice of very dense alloys down to either tungsten- or uranium-base materials.
