Classification of copper-aluminum composite materials
According to different uses and structural forms, copper-aluminum composite materials are mainly divided into the following types:
Double-layer structure: such as copper-aluminum composite plate (copper-coated aluminum), copper-aluminum composite strip.
Three-layer structure: such as copper-aluminum-copper (C-A-C) or aluminum-copper-aluminum (A-C-A) three-layer composite structure, used to improve double-sided electrical or thermal conductivity.
Special-shaped composite parts: such as copper-aluminum composite bars, copper-aluminum composite wires, etc., suitable for scenes requiring complex forming.

Technical Specifications

Preparation process of copper-aluminum composite materials
1. Explosive welding technology
Explosive welding is currently the most commonly used high-energy physical method for preparing copper-aluminum composite materials. Through explosives in a controlled environment, instantaneous high-voltage waves are triggered, so that copper and aluminum collide at high speed in a very short time and complete metallurgical bonding to form a bonding interface. This process can overcome the problem of brittle intermetallic compounds between copper and aluminum, and has a high-strength bonding effect.
2. Rolling composite process
Rolling composite is to press copper and aluminum into a whole at a certain temperature and pressure by hot rolling or cold rolling. This method is suitable for large-scale continuous production and is widely used in the preparation of copper-aluminum composite strips and plates.

Advantages of copper-clad aluminum materials
1. Excellent electrical and thermal conductivity
The copper layer gives the material excellent electrical conductivity (the electrical conductivity is close to that of pure copper), and the aluminum layer greatly reduces the overall density of the material, thereby achieving a lightweight and highly conductive performance combination, which is particularly suitable for the field of power electronics.
2. Excellent mechanical bonding strength
The metallurgical bonding interface formed by high-energy explosive welding or rolling composite has extremely high shear strength and anti-peeling properties, ensuring that no material delamination or breakage occurs during use.
3. Good processing and forming properties
Copper-clad aluminum materials can be sheared, bent, stamped, welded and other conventional metal processing operations according to specific needs. They are highly adaptable and suitable for the preparation of complex parts.
4. Significant cost advantage
The price of aluminum is much lower than that of copper. The use of copper can be greatly reduced through copper-clad aluminum materials, thereby significantly saving raw material costs and improving economic efficiency.

Application fields of copper-composite aluminum materials
1. Power and electronics industry
Copper-composite aluminum bars are widely used in low-voltage power distribution systems, bus ducts, switch cabinets and other equipment. They can effectively replace pure copper conductors to achieve lightweight and low cost. Copper-aluminum composite strips can also be used in cable connections, flexible connections and terminal blocks.
2. Automobiles and rail transit
In new energy vehicles, copper-composite aluminum materials are used for power battery connections, busbars and electronic control system wiring, taking into account both conductive performance and lightweight requirements to improve endurance efficiency.
3. Communication and heat dissipation systems
Copper-aluminum composite plates can be used in heat dissipation components such as 5G communication equipment and CPU radiators. The copper layer conducts heat quickly and the aluminum layer diffuses heat, effectively improving thermal management performance.
4. New energy and photovoltaic industry
Copper-composite aluminum bars are widely used in photovoltaic inverters, battery packs, and charging piles. They take into account current carrying capacity and weight control, and are important functional structural materials in photovoltaic systems.
