The melting point of tungsten is the highest in metal, and its outstanding advantage is that high melting point brings good high temperature strength and corrosion resistance, which shows excellent characteristics in military industry, especially in weapons manufacturing. In the weapons industry, it is mainly used for the production of various armor piercing warhead. Through powder pretreatment technology and large deformation hardening technology, Tungsten Alloys the tungsten alloy refines the grain of the material, and the grain orientation is elongated to improve the strength and toughness of the material. The main battle tank 125ⅱ type Armor piercing tungsten core material developed in our country is W-NI-FE, adopting the variable density blank sintering process, the average performance reaches the tensile strength of 1200 MPA, the elongation is more than 15%, and the War Technical Index is 2000 meters distance penetrating 600 mm thick homogeneous steel armor. At present, tungsten alloy is widely used in main battle tank with long diameter ratio armor piercing, Tungsten Alloys medium and small caliber air defense armor piercing projectile and super high speed kinetic energy projectile-core material, Tungsten Alloys which makes all kinds of armor piercing projectile have more powerful breakdown power.
The application of tungsten alloys has a wide prospect of development, from sporting goods to offshore oil drilling. It is easier to process than pure tungsten, with tensile strength higher than carbon steel, about twice times as much as brass and cast iron. Low thermal expansion coefficient, good corrosion resistance,
Tungsten alloy has been widely used in national economy and defense industry. The aerospace industry is used for gyroscope rotors, counterweight and balance materials, Tungsten Alloys and for guiding devices and damping devices;
The key of alloy preparation process flow chart is sintering process. The sintering temperature is generally 1400~1600℃ and the liquid phase is produced, which is advantageous to the densification of the alloy, and the sintered alloy can reach more than 99% of the theoretical density.
High density, high strength, good plasticity and machinability, good conductivity and thermal conductivity, good corrosion resistance, good weldability, Tungsten Alloys excellent absorption ability for all kinds of rays.
Why is tungsten alloy used in military?
Today, tungsten alloys are increasingly becoming raw materials for military production, such as bullets, armor and artillery, shrapnel, grenades, shotguns, bullet warheads, bulletproof cars, armored tanks, cannon parts, guns, etc. One of the main uses of tungsten alloys is kinetic energy penetrator, Tungsten Alloys which competes directly with depleted uranium (DU). The Army research shows that the excellent performance of depleted uranium bombs comes from the partial decomposition of ballistic missile penetration. As a result, it has been suggested that if partially decomposed into tungsten alloys, the permeability of these alloys will be comparable to depleted uranium (depleted uranium has become an environmental issue).
