Tungsten heavy alloys are usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co、Mo、Cr, etc., The most important property for tungsten alloy cube is that small volume with high density, which means it could be used in some fields need the little but heavy parts, especially for military defense, projectiles it play very important role. Heavy-metal tungsten alloys were identified as likely replacements, but these materials were not tested early in the munitions development process for adverse health effects as embedded fragments.Main Application of tungsten alloy: For making rotors of dynamic inertial materials, the stabilizers of aircraft wings, shielding materials for radioactive materials, containers in hospitals and for radioactive isotope (Cobalt 60), and for material of armor piercing bullets and moulds or the military use, etc.
Properties and appliance of tungsten heavy alloy in military:
In order to reduce the adoption of environmental hazardous materials in the military field, tungsten related products are used as a nontoxic substitute for lead and depleted uranium in bullet and shot. High-density metals such as tungsten are now widely employed; the goal is to create functional, high density, non-toxic arms projectiles with controlled impact behavior. The special properties of tungsten alloy render it the most ideal counterweight materials, far more than already listed on our website.
Nowadays, tungsten heavy alloy is increasingly adopted as the raw material to make parts of military products, such as bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads, bulletproof vehicles, tank panzers, cannons, firearms, etc.
Advantages of military tungsten alloy:
Excellent mechanical properties such as high vibration-damping capacity and high Young's modulus.
Excellent radiation-shielding property
High thermal conductivity with low thermal expansion coefficient
Higher high-temperature strength and thermal shock resistance
High oxidation resistance and corrosion resistance
The military tungsten alloy block part adopts the technology of metal injection molding which near net shape technology and the processing methods compared with conventional superiority is a manufacturing quality precision component. Directly manufacturing small sized part about 0.1g to 200g with complicated geometric shapes, compared to investment casting and powder metallurgy, the metal injection molding parts' tolerance can be held to +/-0.1~0.5%, having high relative density 95 percent to 99 percent and more consistent microstructure and higher mechanical property. Without or only minute quantity of machine work needed, material use rate as high as 97%, part dimension being of small manufacture tolerance, and repeatability, adjustable material composition, fine parts surface smoothness, improvable strength and wearing resistance by heat treatment.
