This new tungsten tin alloy shotgun bullet core has higher density than tungsten alloy shotgun bullet core to reach the ideal range. The density and hardness of this bullet core of shotgun can be controlled, which can effectively reduce the wear of the barrel. The main component of tungsten tin alloy is non-toxic, so that it is harmless to people and the environment. The raw material of this new tungsten tin alloy shotgun bullet core is composed of tungsten powder, tin powder and iron powder. The weight ratio of each component is: 30-70 parts of tungsten powder, 28-60 parts of tin powder, 2-10 parts of iron powder.
