Since at least World War II, tungsten alloys have proven their worth in ordnance applications. The great properties of tungsten alloys make them applicable in hyper-velocity, armor-penetrating applications, fragmentation devices and kinetic energy penetrators. We can offer tungsten heavy alloy ordnance components (military tungsten alloy) in spheres, cubes, swaging rods and projectile shapes.
Manufacturing techniques and additives allow us to vary certain properties, such as elongation, ultimate tensile strength, and hardness of our tungsten alloys in order to meet your needs.
