Military Field
Application
Copper steel composite materials' low-pressure infiltration composite technology is a new technology that has emerged in the domestic metal composite sheet material field. In addition to having the common characteristics of high strength, good heat resistance, thermal stability, plasticity, toughness, and wear resistance, copper clad steel plate also has advantages such as high yield rate and high precision in the military gun shell manufacturing industry. It helps improve the quality of gun shells.
The composite material has excellent consistency, ensuring uniformity between bullets and bullet casings; with large batch size, continuous processing can be achieved, greatly improving production efficiency. The surface quality is comparable to pure copper, and the yellow copper surface of the copper composite panel has lubrication effects, which can reduce the wear on gun barrels and lines when shooting. Now widely used in gun shell and bullet products, as well as other military applications. The sales network for military copper composite material has covered the globe and received consistent praise from many customers.

Copper steel composite material is a high-performance bimetallic solution widely used in the military manufacturing industry, especially in bullet shell production, ammunition components, and precision stamping parts. It combines the excellent ductility and surface properties of copper with the high strength and structural stability of carbon steel.
In modern ammunition manufacturing, consistency, precision, and production efficiency are critical. Traditional single-metal materials often fail to meet these requirements in high-speed mass production. Copper clad steel plate provides a balanced solution that improves forming performance while reducing material cost and ensuring stable product quality.
With advanced composite bonding technology, copper steel composite materials are now widely used in military-grade applications where reliability, uniformity, and high-volume production are required.
Copper steel composite material is a metallurgical bonded plate made by combining a copper layer and a steel substrate through advanced rolling or bonding processes. The copper layer provides excellent surface properties, including corrosion resistance, lubrication performance, and forming ability, while the steel base provides strength and rigidity.
This structure allows the material to perform well in demanding manufacturing environments, especially in continuous stamping and forming processes used in ammunition production.
Compared with pure copper materials, copper steel composite significantly reduces cost while maintaining similar surface performance, making it an ideal material for large-scale industrial production.
One of the most important applications of copper steel composite material is in military ammunition manufacturing, particularly in bullet shell and gun shell production.
Copper steel composite plate is widely used for producing bullet shells due to its excellent formability and stable mechanical behavior during high-speed stamping processes. It ensures smooth shaping, reduced cracking risk, and high production efficiency.
In addition to bullet shells, the material is also used in various ammunition parts that require consistent thickness, controlled deformation, and high precision.
Modern ammunition production lines require materials that can support continuous, high-speed processing. Copper clad steel plate provides stable performance under repeated forming cycles, making it suitable for automated production systems.
Copper steel composite material offers a range of technical and economic advantages that make it a preferred choice in military manufacturing applications.
The metallurgical bonding structure ensures uniform thickness and stable mechanical properties, which is essential for precision stamping in ammunition production.
The copper surface layer provides good ductility and lubrication behavior, allowing smooth deformation during high-speed forming processes without cracking or surface defects.
The steel substrate provides structural strength and prevents deformation issues during processing and transportation.
Compared with traditional materials, copper steel composite improves production yield by reducing waste, defects, and rework rates in mass manufacturing.
By replacing full copper materials with a composite structure, manufacturers can significantly reduce raw material costs while maintaining required performance standards.
The material is designed for continuous coil-to-coil processing, making it ideal for automated ammunition production lines.
Copper steel composite materials are produced using advanced metallurgical bonding technology, ensuring strong and stable interlayer adhesion.
The most common production methods include:
Copper and steel layers are bonded under high temperature and pressure, forming a permanent metallurgical bond. This process ensures excellent mechanical integrity and uniform material structure.
After bonding, the material undergoes surface finishing to ensure consistent thickness, smooth surface quality, and stable performance during stamping operations.
Each batch is strictly tested for bonding strength, thickness tolerance, and mechanical performance to ensure compliance with industrial and military standards.
