Copper Clad Aluminum Bimetallic Plate: Product Details

A Copper clad aluminum bimetallic plate is a type of metal composite material made by metallurgically bonding a layer of copper onto an aluminum base. This process combines the superior conductivity and corrosion resistance of copper with the lightweight and cost-effectiveness of aluminum, offering a high-performance solution for various industrial and electrical applications.

Technical Specifications

Below are the detailed specifications of the Copper Clad Aluminum Bimetallic Plate:

Property	Value Range (Typical)
Copper layer thickness	0.05 mm – 2.0 mm
Aluminum base thickness	0.5 mm – 20 mm
Electrical conductivity (Cu side)	≥ 98% IACS
Bonding strength	≥ 100 MPa (explosion welded)
Thermal conductivity	180–220 W/m·K (composite average)
Density	~4.2 g/cm³ (depends on layer ratio)
Operating temperature	-40°C to 200°C

Advantages of Copper-Aluminum Bimetallic Plates

1. Enhanced Cost-Effectiveness
Copper prices are considerably higher than aluminum. By using a copper clad aluminum bimetallic plate, manufacturers can reduce raw material costs while still maintaining good electrical and mechanical properties.
Weight reduction: Aluminum has one-third the density of copper.
Material savings: Only the copper surface is used for conductivity, reducing total copper consumption by 60–85%.
2. Thermal and Electrical Performance
Excellent conductivity, ideal for current-carrying applications.
High thermal performance, suitable for applications like heat sinks and power distribution plates.
3. Improved Corrosion Resistance
Copper’s natural corrosion resistance enhances the overall durability of the plate. the copper layer protects the underlying aluminum from galvanic corrosion, when the plate is used in outdoor or marine environments.

Application Areas of Copper Clad Aluminum Bimetallic Plates

1. Electrical Power and Distribution
Busbars and electrical connectors
Transformer windings
Substation and switchgear components
The copper surface ensures low contact resistance, while the aluminum core reduces overall weight and cost.
2. Automotive and EV Industry
Battery connections and terminals
EV charging systems
Heat spreaders in electronic control units
EV manufacturers benefit from the light weight of aluminum and the superior conductivity of copper in high-current applications.
3. Electronics and Telecommunications
RF shielding enclosures
Thermal interface materials for CPUs and GPUs
PCB base plates and substrates
These applications demand materials that can efficiently conduct both electricity and heat while minimizing weight and cost.
4. Renewable Energy Systems
Solar panel connectors
Wind turbine grounding bars
Energy storage systems
The material ensures durability and performance in demanding environmental conditions while keeping system weights manageable.
