Tungsten alloy small caliber core is gradually replacing lead small caliber core due to its good performance, and is becoming the mainstream of small caliber cores. Tungsten alloy has a higher density than lead, so it has wider applications. And small caliber core made of tungsten alloy is relatively low-toxic and environmentally friendly, so that it can reduce the adverse effects of environmental hazards caused by lead small caliber core. In a word, tungsten alloy is gradually replacing the application of lead in the military field.
