1mm to 100mm thickness copper clad aluminum sheet

Product Page: 1mm to 100mm Thickness Copper Clad Aluminum Sheet

Product Introduction

1mm to 100mm thick copper-aluminum plate is a bimetallic or multimetallic composite material formed by tightly combining copper and aluminum layers through explosive welding, rolling composite or hot rolling technology. Usually the surface layer is high-purity copper (such as T2, TU2), and the matrix is ​​high-strength aluminum (such as 1060, 3003, 5052, 6061, etc.), and the two are combined to form a stable metallurgical bonding interface.

Thickness range
The thickness of copper-aluminum plate ranges from 1mm to 100mm, meeting the requirements of different engineering structures and electrical and thermal conductivity:
1mm-5mm: Suitable for precision parts such as electronic connectors, battery connectors, small electrical components.
5mm-20mm: Commonly used in medium-sized structures such as rail transit conductive bars, power busbars, and reactors.
20mm-100mm: Mostly used in high-load applications such as large transformer conductors, military equipment, and shipbuilding industry.

Technical Specifications

Performance advantages of copper-aluminum plates with a thickness of 1mm to 100mm
1. Excellent electrical and thermal conductivity
The electrical conductivity of copper is as high as 99.7% IACS, and aluminum is about 60% IACS. After compounding, it not only guarantees excellent electrical conductivity, but also has good heat dissipation capabilities, which is very suitable for thermal control components in electrical systems.
2. Material weight reduction and cost advantages
Compared with pure copper materials, copper-aluminum plates use lightweight aluminum to replace part of copper materials, which can reduce weight by 30%-50% and significantly reduce material costs. This is especially important for industries such as new energy vehicles and aerospace that have extremely high requirements for lightweight.
3. High strength and good formability
Copper-aluminum plates with a thickness of 1mm to 100mm have both the weldability and oxidation resistance of copper and the ductility and strength of aluminum, and perform well in processes such as stretching, stamping, and bending.
4. Excellent corrosion resistance
In neutral and weak acid environments, the copper-aluminum composite structure forms a self-passivation protective layer to effectively prevent corrosion, and is particularly suitable for humid, acidic and alkaline gas environments.

Application fields of copper-aluminum plates with thickness of 1mm to 100mm
1. Power industry
Copper-aluminum plates are widely used in transformers, high-voltage busbars, reactors, conductive bars and other equipment. Various thickness specifications from 1mm to 100mm can cover the conductivity requirements of different voltage levels.
For example: 10mm thick copper-aluminum composite bars are used for 35kV busbar systems;
Thick plates above 50mm are used for conductor lugs of transformers in large substations.
2. New energy battery industry
In power batteries, 1mm-3mm copper-aluminum plates are used to make copper-aluminum transition connectors and lug connecting strips to solve the problems of electrochemical corrosion and thermal expansion coefficient mismatch between different metals.
3. Rail transit and aerospace
The advantages of aluminum's light weight and high strength combined with copper's stable conductivity make copper-aluminum plates an ideal material for rail transit vehicle cable connectors and aviation grounding systems, especially suitable for earthquake resistance and high temperature resistance.
4. Electronics and heat dissipation
In electronic packaging modules, copper-aluminum plates with a thickness of 3mm-10mm are widely used in IGBT modules, LED heat sinks, microwave communication equipment and other products due to their high thermal conductivity and structural stability.
5. Building and curtain wall decoration
Copper-aluminum plates with a thickness of 5mm to 10mm are also commonly used in high-end building facade decoration and interior wall panels. They are not only decorative and functional, but also greatly improve the grade of the building.
