Explosion Bonding Copper Clad Aluminum Product Page

Product Introduction

Explosion Bonding Copper Clad Aluminum is a high-performance composite material combining the excellent conductivity of copper with the lightweight and corrosion resistance of aluminum. This innovative product is manufactured using advanced explosive welding techniques, creating a strong metallurgical bond between the two metals. Widely used in industries such as electronics, power, marine, and environmental protection, Explosion Bonding Copper Clad Aluminum offers unmatched versatility and performance.

Technical Specifications

Manufacturing process of explosive copper composite aluminum plate
1. Material pretreatment
To ensure the cleanness of the composite interface and the firm bonding, the copper plate and the aluminum plate need to be strictly pretreated, such as surface deoxidation, degreasing, mechanical polishing and other processes to improve the contact activity between the metals.
2. Process parameter control
The manufacturing of explosive copper composite aluminum plate depends on the precise design of explosion parameters, including the type of explosives, charge density, the spacing between the flying plate and the bottom plate, the composite angle, etc. Different parameters will directly affect the propagation speed of the explosion wave, the interface morphology and the bonding strength.
3. Subsequent heat treatment and leveling
Some products need to be heat treated or vacuum annealed to improve the residual stress after the composite and enhance the uniformity of the organization. Through rolling, leveling and other processes, the target size accuracy and plate surface flatness can also be achieved.

Advantages of Explosive Copper Composite Aluminum Plate
1. Highly complementary material properties
Explosive copper composite aluminum plate combines the advantages of copper's high electrical conductivity and high thermal conductivity with aluminum's light weight, high plasticity, and good corrosion resistance. In application scenarios such as electrical engineering, heat exchanger manufacturing, and hot pressing molds, this composite material not only has excellent performance, but also effectively reduces costs.
Function of copper layer: Provides conductivity and wear resistance;
Function of aluminum base: Reduces material density and improves cost performance.
2. High-strength metallurgical bonding interface
Compared with traditional mechanical connection or brazing process, explosive copper composite aluminum plate forms a wavy interface through instantaneous ultra-high pressure impact, effectively avoiding the formation of brittle intermediate layers between metals, and has extremely high shear strength and anti-peeling ability. According to tests, its interface bonding strength usually exceeds the yield limit of the material itself.
3. Good processing performance
While having a high-strength bonding interface, the explosive copper composite aluminum plate still maintains good ductility and processability, and can be subjected to a variety of secondary processing processes such as shearing, stamping, bending, and deep drawing to meet the manufacturing needs of components of different shapes and structures.
Application fields of explosive copper composite aluminum plate
1. Electrical conductor manufacturing
The electrical conductivity of copper is nearly twice that of aluminum, but its cost is much higher than that of aluminum. By using explosive copper composite aluminum plate, the cost of raw materials can be greatly reduced while maintaining excellent electrical conductivity. It is often used to manufacture high-current busbars, transformer conductive terminals, cable connectors and other products.
2. Heat exchange equipment industry
Explosive copper composite aluminum plate is widely used in the manufacture of condensers, heat exchangers and other equipment. The copper layer can quickly conduct heat, while the lightweight characteristics of aluminum reduce the weight of the entire equipment, which is very suitable for occasions with high requirements for heat exchange efficiency and structural strength.
3. Metal structural parts
In aerospace and high-end machinery manufacturing, explosive copper composite aluminum plate can be used to manufacture lightweight and high-strength structural parts, especially in electromagnetic shielding, vacuum cavity, electrical connection panel and other fields. Its interface stability and corrosion resistance ensure the reliability of long-term service.

Quality inspection standards for explosive copper composite aluminum plates
