Copper Clad Aluminum Sheet

Product Overview

 Copper clad aluminum sheet,also known as copper-aluminum composite plate, is a high-performance bimetallic material that combines the excellent electrical and thermal conductivity of copper with the lightweight and cost-effective properties of aluminum. It is produced using explosion bonding technology a solid state welding method that creates a strong metallurgical bond between dissimilar metals under high pressure and high velocity.

This product is ideal for applications that require good conductivity weight reduction and reliable mechanical integrity across electrical power automotive thermal and electronic industries，etc.

Manufacturing Process Explosion Bonding Technology

 Our copper clad aluminum sheets are manufactured using a controlled explosion bonding process. This advanced method uses precisely calculated explosive energy to drive copper and aluminum plates together at high speed forming an atomic level metallurgical bond without melting either material.

1. Key steps including:
Surface preparation and alignment of copper and aluminum plates
Use of explosive charges under strict safety and process control
Post bonding rolling annealing and flattening
Surface finishing cutting and final inspection

2. Advantages: Compared to traditional roll bonding this technique provides the following advantages:
a.  Stronger interfacial bonding
b.  No intermetallic layer formation
c. Better high temperature stability and conductivity retention
d. Excellent peel strength and no delamination during processing
