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, Tungsten Alloys with tensile strength higher than carbon steel, about twice times as much as brass and cast iron.
Tungsten alloy is a kind of tungsten matrix (W content 85-99%), and the addition of Ni, Cu, Co, Mo, Cr and other elements of the alloy. According to the composition of the alloy and the use of W-ni-fe, W-NI-CU, W-co, W-WC-CU, W-ag and other major series, the density of up to. 5-19 0g/cm3, Tungsten Alloys which is known as the high gravity alloy, has a series of excellent characteristics, which is more important than the average proportion of 5-18.75g/cm3, high strength: Tensile strength is 700-1000mpa, absorbing ray ability is strong: its ability is higher than lead $number, heat conductivity is big: 5 times times of die steel; thermal expansion coefficient is small: only iron or steel 1/2-1/3, good conductive properties With good weldability and processability. Tungsten Alloys Since the high gravity alloy has these excellent functions, it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medicine and other industries.
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. Tungsten Alloys One of the main uses of tungsten alloys is kinetic energy penetrator, 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.
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, Tungsten Alloys it is mainly used for the production of various armor piercing warhead. Through powder pretreatment technology and large deformation hardening technology, 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, Tungsten Alloys 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, which makes all kinds of armor piercing projectile have more powerful breakdown power.
