Application of Copper-Steel Composite Material in Military Bullet Casings: Low Cost, High Performance

In the field of military equipment, material performance and cost control remain core issues. As an innovative technological product, copper-steel composite material is emerging prominently in the field of ammunition manufacturing with its groundbreaking cost-performance advantage, particularly showing revolutionary potential in the application of bullet casings.

Traditional pure copper casings possess excellent ductility and corrosion resistance, but they face two major pain points: high raw material costs (due to copper prices remaining high for a long time) and risks associated with strategic resource dependence. Through composite rolling processes, copper-steel composite material combines a copper layer with a high-strength steel substrate, maintaining the critical performance of bullet casings while reducing material costs by over 40% compared to pure copper. This provides an economic solution for large-scale ammunition production.

This military-civilian integration innovative material not only meets the need for cost reduction and efficiency enhancement in defense equipment but also provides a safeguard for strategic metal resource reserves. Its application scenarios are expanding into more military fields.
