Zusammenfassung:	The invention relates to a lead-free environment friendly type high density bullet and a preparation method of the environment friendly type high density bullet. The bullet materials comprise, by weight, 100 parts of high-molecular polymers, 500-2000 parts of tungsten powder, 0.05-100 parts of tungsten fiber, 0.05-200 parts of iron powder, 0.5-5 parts of compatilizer, and 0.05-1 part of antioxidants. The preparation method comprises the steps of (1) ingredient mixing, (2) extruding and granulating, (3) injecting and forming, (4) bullet billet sizing, and (5) bullet billet copper plating, and a final product is obtained. The lead-free environment friendly type high density bullet has no lead element, the pollution to environment and the harm to human, animals and plants of traditional bullets with lead are effectively avoided.
