Nearly 30 years, due to the high density tungsten alloy used successfully in the kinetic energy penetrators, and significantly improves the armor-piercing power, the consumption of the alloy is increased significantly. Penetrators alloy materials development through the following stages: high-strength steel -WC Carbide - sintered tungsten alloy - deep processing of high-density tungsten alloy (deformation processing and heat treatment) - High-density tungsten alloy composites.
In 1976, the fourth generation of armor-piercing tungsten alloy bomb core material base developed. By the 1980s, some of the major countries of the world are on a dozen tanks and dozens of artillery equipped with a tungsten alloy penetrators, artillery caliber from 60mm to 125mm, the maximum weight of up to bomb core 4kg, and assembled using a variety of forms (eg overall, multi-block, plus steel sleeve, etc.). Since the study and improvement of the mechanical properties and ballistic performance of high-density tungsten alloy, coupled with the supply of tungsten raw materials continue to improve, some industry advocates tungsten can and should be used as the main material of armor-piercing bomb core.

High density tungsten alloy bomb core material for a long time focused on the alloy composition, powder metallurgy, heat treatment and deformation processing technology, but also inseparable from the scope of homogeneous material, it should be said to have made ​​gratifying achievements, the strength of the material is a major breakthrough. After 80 years, the overseas development of a variety of composite materials, such as complex 丝加基 plated material, composites infiltration wire (or fiber) composite powder (or wire) and matrix composed of uranium - tungsten composite materials and high density tungsten alloy fiber-reinforced composite materials.

Begins with a high density of armor-piercing tungsten alloy mid-1970s, only 15 years to complete from the state to the several stages of sintering heat treatment and deformation processing of state and other states of the replacement, and were in a different caliber and variety of shells successful application on the type of projectile.

Tungsten round dropshot weight offers the advanced performance of tungsten at a great price. Tungsten round dropshot weight is very useful for feeling bottom compositions, especially when fishing muddy or sandy bottoms, and the increased hardness of their tungsten composition makes them much more sensitive than comparable lead weights.

Tungsten round dropshot weight is more compact than lead weight owing to the higher density of tungsten, they are also environmentally friendly as well, which is helpful for protecting our fisheries.

Air defense, anti-radiation, anti-surface and other types of warhead commonly used fragmentation warhead, mainly rely fragment kinetic-kill goal. Fragmentation can effectively kill the target and hit the target speed when fragmentation is closely related to the shape and quality. Fragments of spherical tungsten alloy (tungsten beads) due to the high density, attenuation coefficient, strong armor-piercing capability, become anti-aircraft, anti-radiation, the main choice of object surfaces and other types of anti-fragmentation warhead design.

Tungsten alloy spherical fragments due to its large density, speed, and ability to maintain strong piercing has gradually become the preferred elements warhead damage, so characteristic of research piercing tungsten alloy spherical fragments have a very important value. For the past fragments piercing questions, mostly concentrated in the conventional projectile velocity (500m / s ~ 1300m / s) hit Steel Fragments of the armor-piercing experiments and mechanism study of a single homogeneous steel target under the target conditions, and most of that: the same bomb target under the condition, completely through the thickness of the target plate hit the target with increasing speed must increase. For high projectile velocity (1300m / s ~ 3000m / s) piercing, pressure close to or exceed the material strength, impact body and the target material presented liquidity. In addition, with the increase of the target hit rate, tungsten alloy finite thickness of the initial invasion of impactor plate erosion and fragmentation phenomenon occurs, have a greater impact on the piercing process. Thus, the specific quality tungsten alloy fragments of penetration and steel target body there is a limit.

High quality tungsten alloy penetrator is an important symbol of national materials technology development, but also an important material for high performance kinetic energy penetrators, the development level of the relationship to improve our level of equipment needed weapons and can win a local war. To this end, should address some of the issues and the actual needs of the existing form a highly systematic research institutions and complementarity in order to promote China's missile technology developed tungsten alloy material to low-input, high-yield, high-level and high-practical direction, to improve the overall performance of armor-piercing tungsten alloy materials.

With the development of a tungsten alloy penetrators material, we should pay attention to the five major areas:

Armor-piercing shells performance is the most important performance indicators tungsten alloy, especially playing a board study of the mechanism of action, while also strengthening research adiabatic susceptibility tungsten alloy materials; 2.in order to improve anti-aircraft missiles and armor-piercing capability of damage, materials and systems research through burning complex functional elastomer material is friable Bouncing tungsten alloy body should carry out; 3.high toughness tungsten composite armor piercing is an important development direction of future ultra high-speed kinetic energy penetrators should be further strengthened with ultra high-speed kinetic energy penetrators research body piercing tungsten composite material beam; 4.Although China is a country rich tungsten, but reserves are limited, should be strengthened tungsten alloy shells with tungsten scrap and waste recycling, and low consumption of raw materials technology research and development. 5.Our coastline is very long, for the defense of coastal areas to prevent salt spray, seawater and humid environment for armor-piercing tungsten alloy with corrosion problems have been on the agenda, for which there should be targeted to carry out bomb tungsten alloy corrosion protection technology research.
