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.

High density tungsten alloy shells require both high strength and good toughness at ensuring high density premise. Therefore, in order to further improve the strength and toughness of tungsten alloy, tungsten alloy deformation strengthening the need for in-depth study.

Currently, the tensile strength was prepared using powder metallurgy high density tungsten alloy (sintered) is generally up to 900MPa ~ 1 000 MPa, elongation between 20%~ 30%; but after plastic deformation strengthening, its strength can be greater margin improved plasticity declined. After plastic deformation, tungsten alloy strength can be more than 1400 MPa, elongation can be maintained at about 10%.

Rolling, rotary forging, torsional deformation, deformation strengthening hydrostatic extrusion and other materials to improve the strength of the alloy of tungsten are the effective way to ensure a certain toughness, but also effective grain refinement. Forging deformation is used to improve the strength of tungsten alloy , conventional deformation is about 15. Strength of tungsten alloys increases with the amount of deformation increase, the greater the amount of deformation of tungsten particles greater degree of deformation, and the deformation degree increase would result in fracture transfer to tungsten particles. Rolling may also be a larger amount of deformation of the deformation and to ensure uniformity, and to make a large grain broken into small grains, and with a uniform distribution of the microstructure; rolling can increase the density and reduce the void tungsten rod , improve production efficiency and reduce manufacturing costs. Rotary forging effect can improve the strength and armor-piercing tungsten alloy, after multiple passes swaging, the mechanical properties of strength and hardness of tungsten alloys have relatively spin before forging a more substantial increase, but the elongation decreases. Hydrostatic extrusion technology is a hard plastic deformation of materials processing technology, the main sub-cool liquid extrusion and hot hydrostatic extrusion, it is one of the most effective tungsten alloy deformation strengthening the current method, it has a deformed to obtain more a large amount of deformation characteristics and can greatly improve the strength of the material.

Preparation of military bullets, armor-piercing shells and other materials generally require a high-density, high strength, high temperature resistant, not easily deformed and other characteristics. The high-density tungsten alloy just to meet their individual requirements. Therefore, the preparation of technical studies tungsten alloys in the manufacturing of military ballistic aspect is particularly important.

Tungsten grain refinement become a new hot spot of high-density tungsten alloy research, using mechanical alloying (MA), prepared by condensation drying method, chemical vapor deposition method, spray drying, sol-gel method and other methods of pre-alloyed powder, and the use of appropriate process may be prepared by a very fine powder. Furthermore, the reaction process may be a spray-step synthesis of fine grain, multi-component, pre-alloyed tungsten-based alloy powder, the powder can be a tungsten-based alloy at a temperature well below the melting point of the binder phase sintered to high density.

MA process for preparing nanocrystalline tungsten alloy composite powder, by sintering atmosphere of hydrogen at atmospheric pressure and tungsten grain densification during sintering behavior grew, MA process for preparing nanocrystalline powders can promote densification, so that densification temperature reduced by about 100 ℃~ 200 ℃, when the solid-phase sintering temperature can be generally obtained 3μm~ 5μm grain size of fine grain high-strength alloy interface. They also nano-tungsten alloy injection molding studied, indicating that 1 350℃ ~ 1 450 ℃ solid phase sintering to achieve full density i.e., the final alloy grains is about 3μm, tensile strength greater than 1200MPa. Temperature and pressure can significantly improve green density, temperature and pressure radial contraction blank blank room temperature is less than the radial contraction, and temperature and pressure can improve the microstructure of tungsten alloy. Also, the use of pre-oxidized tungsten alloy activated sintering, the sintering temperature can be lowered to reduce the tungsten alloy deformed and obtain a dense tungsten alloy, and can improve the tensile strength and elongation of tungsten alloy.

Tungsten skinny dropshot weight is great for coming through rocks and other underwater obstructions.

Tungsten skinny dropshot weight’s shape allows them to stay on top of cracks and narrow gaps in the rock, and the higher density of their tungsten composition makes them much more compact than comparable lead weights, which makes them extremely sensitive allowing you to feel every pebble across the bottom and the lightest of strikes. Tungsten is also much harder than lead, which means you can better detect anything your weight comes into contact with.

If you are new to drop shotting or having issues detecting subtle strikes, tungsten skinny dropshot weight is for you.
