Tungsten in armor-piercing shells is as the main material for core, called tungsten alloy penetrators. The armor-piercing bullet’s piercing capability is closely related to the density of core, and therefore, in order to improve the armor-piercing capability, bomb cores are manufactured using high-density material, and the core material must have sufficient strength, hardness and toughness, which was in line with those of tungsten conditions.

Depleted uranium is also popular bomb core material, however, the depleted uranium is great harm to the environment, and the mechanical properties of tungsten alloy penetrators in friable, by controlling the kinetic energy penetrator materials required for the performance of his, but also has the potential to achieve the crushing effect, so tungsten alloy is a priority material used as penetrators.

Liner is also known as cavities or hollow charge. Liner has broken resistance, corrosion resistance, and high permeability etc characteristics, thereby requiring density liner material is high and with good scalability, so that the jet can be fully stretched before erosion without breaking. As tungsten is with high melting point, high density, good machining performance characteristics, becomes the very promising new drug liner material for liner. Compared to depleted uranium liner, tungsten alloy liner is in more favorable prices and environmental friendly.

Tungsten alloy gyroscope rotor advantages includes:

1. Tungsten alloy gyroscope rotor is with high density. For high density measurement control of gyroscope at high speed rotation state, it requires the material having high mechanical properties and density of the material homogeneity.

2. Tungsten alloy (W-Ni-Cu) is non-magnetic. To avoid surrounding interference of the magnetic field, gyro rotor must be non-magnetic, therefore, tungsten alloy, which is non-magnetic, was used. By unremitting efforts, and the development was succeed soon and applied in the domestic aircraft gyro navigation and the first artificial satellite.

As lead bullets shot will cause corrosion, contamination of soil and potentially lead lye into the local water supply, serious threat to people's health if shot at the ground or earthen debris narrow aisle. In order to avoid the lead bullets environment pollution, the current production of bullets is using tungsten alloy to create "green bullet", the so-called "green" bullet only refers to its terms for less environmental pollution.

And the lethality of tungsten alloy bullets are superior to lead bullets, as tungsten alloy is with features of high density, its volume is much smaller than the of lead bullets in limited weight, so the penetration of tungsten alloy bullets are much larger than that of lead bullets. So the new tungsten alloy bullets replace the old lead bullets and antimony alloy bullets, becoming the most watched bullets.

Tungsten and tungsten alloys grenade was developed from the 1950s, and the 1970s, the United Kingdom, the United States, West Germany and other countries adopt liquid phase sintered tungsten alloy (W-Ni-Fe and W-Ni -Cu) to manufacture APDS core and grenade warheads, thus it greatly improved the bomb core toughness, and the power of the grenade.

Compared with lead grenade warheads, tungsten alloy grenade warheads are with low toxicity, no environmental pollution. Tungsten alloy grenade warheads’ accuracy, damage and penetrating ammunition can meet or exceed performance requirements of grenade.

With high-density, tungsten alloy is widely used in the production of various high-speed ammunition, especially penetrator, it is the core material of modern penetrators. Environment friendly material tungsten, is almost the only core material choice of high-speed penetrator bombs, but it has been a scarce resource, the United States had for economic and strategic reasons, developed the depleted uranium (uranium-238 primarily) as an alternative material for tungsten penetrator, but has been criticized because of environmental issues.

China has been the most abundant mineral resources of tungsten, during World War II, due to tungsten imports from China was cut off, Nazi German tanks is serious lack of big powerful tungsten alloy penetrator, and Tiger tanks and other weapons are greatly reduced in the fire.

Owing to the special properties of tungsten alloy, such as high density, high melting point, small volume, excellent hardness, superior wearing resistance, high ultimate tensile strength, high ductility, high temperature resistance, etc., gold-plated tungsten brick is more and more popular for public as gold substitution for handicraft, souvenir and gift.

As we know, RMB exchange rate is fluctuating always recently, many and many people would like to purchase much real gold for keeping value, however, it is estimated that real gold would be sold totally one day. Maybe purchasing and keeping gold- plated tungsten alloy brick would make up for this situation.

Tungsten carbide integral fine boring tool is mainly used in batch production lines. In recent years, due to market structure, market needs has been changing, increasingly shorter product cycles, which requires processing machinery and cutting tools have better flexibility. Therefore, in practical applications, although tungsten carbide integral fine boring tool’s price is relatively low, we are not very recommended.

Selection methods:

a. confirm machine interface (optional shank form)

b. confirm the work-piece structure, pore size, depth and materials, etc.

c. Optional boring tool (based on pore size, pore depth, etc.)

d. Optional blade (blade holder according to the work-piece material)
