1. Small volume
High density make tungsten alloy fishing sinker smaller than the conventional lead fishing weighs. It will be hung up far less with a tungsten sinker than with a lead sinker because of its smaller size.

2. Hard
It's harder than lead fishing weight. It will not be stuck in the jowl of the fish. So the shape will be maintained longer.

3. Strong wind resistance
As the high density of tungsten, the tungsten alloy fishing sinker makes your fishing easier. It is extremely sensitive and can actually help you "feel" what the bottom is made of and what your bait is bumping into, such as brush, rocks, mud, etc.

Tungsten fishing sinker is an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard.

The main specifications are: drop type, bullet type, Circular tube type, ball type.

Tungsten copper military alloy is fabricated from the two mutual indissolvable metal of tungsten and copper, which combines the properties of good hardness, high melting point and low coefficient of thermal expansion of tungsten with copper’s of high conductivity and high thermal conductivity, it is a kind of well performance composite. Copper tungsten military material not only has good thermal conductivity and low thermal expansion coefficient, but also can design its thermal conductivity and coefficient of expansion by changing its tungsten copper content.

Tungsten copper military alloy is easy to be machined. And with this series of fine characteristic, so copper tungsten military has been widely used in mechanical, electrical, instruments and other civil industrial, and also is widely in making important as well as complex components for aviation, spaceflight, weapons in the military industrial.

The theory of copper tungsten military materials applied as high temperature material in military use is that when the air temperature is close to event exceed the temperature melting point of tungsten (over3,000 ℃), the content of copper in tungsten copper materials evaporate and then absorb a great deal of heat , which greatly reduce temperature of tungsten copper military made parts. The table below shows the properties of high temperature tungsten copper.

Few materials could continue working in such high temperature. Therefore, one of the important use of tungsten copper military alloy is as high-speed and high temperature airflow ablation and flushing parts in rockets and missiles, such as gas helm, nozzle, throat lining, the nose cones, etc. In addition it still can be used as a medical cover of tank, the tailpipe and orbit materials of electromagnetic gun. With these applications, copper tungsten military materials should be handled strictly as the following two items.

In order to guarantee the properties of high temperature strength, good resistance to ablation, and erosion resistant of tungsten copper military alloy in high temperature ,it must be sure the high density of framework and skeleton intensity of tungsten, therefore, copper tungsten militarymaterials in this application generally contain 5% to 10% copper.

And for the sake of making the tungsten copper military alloy gasification and smoothly reduce the material surface temperature by absorbing large mass of heat, it must be ensure that tungsten skeleton pore have very good connectivity and good capillary function at low copper content.

Tungsten copper military shaped charge liner is part of armor-piercing projectile which plays an important role in action. Commonly used shaped charge liner is taper angle form. Generally, cone angle is ranging from 120 to 160 degrees.

Armor-piercing projectile rely on kinetic energy of the projectile to penetrate armor and destroy the target. Armor-piercing projectile are high velocity, long shooting distance and high precision of shooting, is the main ammunition of tank guns and the anti-tank guns. It also used in naval gun, coastal gun , anti-aircraft artillery and airborne cannon and used for mutilating tanks, self-propelled guns, armored vehicles, ships, aircraft, etc.

The theory of tungsten copper military shaped charge liner is called cavity effect .When the armor-piercing projectile detonates, the high temperature and high pressure instantaniously melting shaped charge ,then forming high temperature and speed metal jet which can sear even burnthrough the armored steel. So it is show that armor-piercing projectile take effective action by the cavity effect rather than rely on the kinetic energy.

Armor-piercing projectile’s armor ability is different when adopting different material of shaped charge. Copper used as material for shaped charge liner with low melting point and good ductility, however the density of copper is low and easily deformation, so it commonly mixed with tungsten to improve the density, which increase the armor ability of tungsten copper military shaped charge liner.

Tungsten copper military gas vane is a device for controlling aircraft, rockets, spacecraft, and the like during those parts of a flight where gas vanes are not effective.Tungsten copper military gas vanes vary in design from plates that change the thrust direction of a gas flow to complicated guide vanes. In aircraft, gas vanes are used during take off and landing conditions .While in rockets and spacecraft they are used during the initial portions of a flight and for control in non atmospheric conditions.

The theory is that when the solid rocket motor outbursts the high temperature, high speed gas flow ,tungsten copper military gas vane can make the copper molten in the structure of tungsten skeleton infiltrate , evaporate, then effusion.

When the tungsten copper changing in the phase state, tungsten copper need to intake large mount of heat for the sake of cooling, and the good thermal conductivity of cooper makes the tungsten copper military gas vane with the function of cooling and keep the ablativity at low extent to satisfy the requirements of controlling system.
