Tungsten alloy green bullet is a common term for the lead-free, small arms ammunition developed by the army in an effort to provide soldiers with environmentally friendly ammunition. Military tungsten alloy is often used to manufacture "green" or lead-free bullet. Such a lead-free bullet typically contains tungsten that is mixed together with either nylon or tin. Tungsten alloys, on the other hand, contain other metals, such as nickel, cobalt, iron, or copper, which are heated to high temperature that allows the materials to bond together. But tungsten alloy green bullets have not been used on the battlefield, just in training operations at a limited number of army installations.
