Chalco pioneered the layered composite technology of aluminum armor plates to meet the different performance requirements of different application environments and parts of use. By using hot rolling composite method, 7072 7A52 7A62 aluminum alloy plates were overlaid and heated. Pressure was applied at a certain amount to produce 5-layer, 7-layer, and 9-layer composite aluminum alloy plates.
Composite aluminum plates are commonly used in military and armor fields, ensuring that military armor plates have the maximum hardness, ductility, explosion-proof performance, and impact resistance at the lightest weight.Quick Quote

- The protection coefficient of composite armor is significantly higher than that of homogeneous armor, so its mass is smaller than that of homogeneous armor under the same bulletproof ability.
- The thickness coefficient of composite armor against armor piercing shells is higher than that of homogeneous armor, so its thickness is smaller than that of homogeneous armor under the same bulletproof ability.
- Composite armor has designability and can be designed with various performance, quality, and thickness according to different needs and combat environments to meet the requirements of different applications.
Composite armor with layered composite structures has become an indispensable protective composite material in recent years due to impedance differences at internal material interfaces, lightweight design, high degrees of freedom, and strong impact resistance.Quick Quote
Advantages of Chalco composite aluminum plate in military
Homogeneous armor is usually only suitable for specific weapons and is difficult to resist various anti armor weapons simultaneously. In order to improve bulletproof performance and respond to different threats, composite armor made of high-performance materials has become the main research direction.Quick Quote
- The outer panel uses hard aluminum, and the very hard panel has high resistance to projectile penetration;
- The high toughness back plate can undergo plastic flow on a large area around the impact point to suppress the debris generated by the intermediate layer;
- Multi interface energy absorption changes the trajectory of the projectile and prevents debris damage through material layering, improving the penetration resistance of composite armor. Even with the same density, the elasticity resistance is higher than that of homogeneous armor.
Production capacity of Chalco armor aluminum plate
