Copper Clad Aluminum Bimetallic Material

Copper-aluminum composite bimetallic materials are made by combining copper and aluminum, two metal materials with significant differences, through physical or metallurgical methods, to form a bimetallic composite material that not only retains the original properties of the two metals but also achieves complementary performance. Its basic structure is usually in the form of "copper-aluminum" or "aluminum-copper-aluminum" layers, and the specific form can be adjusted according to application requirements.

Preparation process of copper-aluminum composite bimetallic materials
1. Explosive composite process
Explosive composite is to control the explosive detonation wave to hit the copper plate at high speed against the aluminum plate, so that the two can be metallurgically bonded in a very short time. This method has high bonding strength and clear composite interface ripples, which is suitable for large-area, high-strength composite requirements.
2. Hot rolling composite process
The hot rolling method is to roll copper and aluminum plates in multiple passes at high temperature to make the interface between the two closely bonded. Its advantages are high production efficiency and relatively low cost, and it is widely used in the production of small and medium-sized composite materials.

Advantages of copper-composite aluminum bimetallic materials

1. Excellent electrical conductivity and lightweight properties
Copper has excellent electrical conductivity, while aluminum is known for its light weight. Copper-composite aluminum bimetallic materials combine the high electrical conductivity of copper with the light weight of aluminum. While maintaining high electrical conductivity, they effectively reduce the overall weight and are ideal materials for power transmission and electronic devices.
2. Significant economic benefits
Compared with pure copper materials, copper-composite aluminum bimetallic materials significantly reduce the use of copper materials while meeting the performance requirements, reducing costs by about 30% to 50%, bringing significant economic benefits to enterprises.
3. Excellent mechanical properties and processing properties
The copper layer provides good tensile strength and wear resistance, while the aluminum matrix has excellent ductility and formability. The overall material can be subjected to a variety of conventional processing operations such as bending, stamping, and welding to adapt to complex working conditions.
4. Excellent interface bonding strength
The copper-composite aluminum material prepared by advanced explosive composite or hot rolling technology has high copper-aluminum interface bonding strength, good anti-peeling performance and stability, ensuring the safety of the material in long-term use.
5. Good corrosion resistance
Aluminum itself has strong anti-oxidation ability, forming a dense oxide film on the surface, which helps to improve the corrosion resistance of the entire composite material, especially suitable for applications in humid or acidic and alkaline environments

Application fields of copper-clad aluminum bimetallic materials
1. Power conductors and busbar systems
Due to its excellent conductivity and low cost, copper-clad aluminum bimetallic materials are widely used in electrical systems such as high and low voltage cable conductors, transformer leads, and busbars. It is especially suitable for replacing traditional pure copper busbars and effectively reducing power transmission losses.
2. Electronic connectors and terminal materials
Copper-clad aluminum materials can not only meet the needs of conductivity, but also facilitate stamping and welding. They are ideal materials for making various electronic connectors, connectors, and automotive wiring harness terminals, with both performance and cost advantages.
3. Electromagnetic shielding and heat dissipation components
In the fields of 5G communications, data centers, industrial control, etc., copper-clad aluminum materials are used to manufacture key components such as heat sinks, housings, and grounding systems with good electromagnetic shielding and heat dissipation properties, improving overall electrical safety and system reliability.
4. New energy and lightweight automotive parts
In the fields of new energy vehicles, rail transit, etc., copper-clad aluminum materials help to achieve lightweight structural parts while ensuring conductivity, and are an important material technology path to achieve energy conservation and emission reduction.
