The caliber of tungsten alloy small caliber bullet cartridge generally ranges from 0.5 mm to 9 mm, including the general specification of 5.56mm, 7.62mm, 9 mm, 0.38 mm and 0.45 mm. tungsten alloy has the density of up to 18.0g/cm3, so the same caliber bullet cartridge can be made from less tungsten alloy material in the same situation. Because of the non-toxic and environmental protection characteristic of tungsten alloy, it gradually replaces lead bullet and becomes the main component of small caliber bullet core, which is used in national defense military field.
This type of small caliber bullet cartridge can be made by the tungsten mixture through powder metallurgy process, so as to get rid of the adverse effect of the environmental harm caused by lead ammunition. It is difficult to manufacture the bullet cartridge with ordinary manufacturing technique; however, Metal Injection Molding (MIM) is an ideal manufacture process to make it. MIM is suitable to manufacture the metal and ceramic component with the property of complex three-dimensional structure, high density, high rigidity, high precision, etc. Smaller, more precise, more complex parts also can adopt MIM method to manufacture.
