COPAL Copper Aluminium Bi-Metal Sheets

The Perfect Blend of Conductivity and Cost-Effectiveness

Our COPAL Copper Aluminium Bi-Metal Sheets are engineered to combine the superior electrical conductivity of copper with the lightweight and cost-efficiency of aluminium. These sheets consist of a solid metallurgical bond between a top layer of copper and a base layer of aluminium, creating a high-performance, corrosion-resistant material ideal for electrical and thermal applications.

Key Features:

• Bimetallic Construction: Solid-state bonded copper layer over an aluminium base ensures consistent conductivity and structural integrity.

• Excellent Electrical Performance: High surface conductivity from the copper layer with reduced overall material cost.

• Corrosion Resistant: The bonded interface resists galvanic corrosion and oxidation in harsh environments.

• Lightweight and Strong: Offers excellent mechanical strength while being significantly lighter than pure copper.

• Custom Dimensions: Available in various thicknesses and sheet sizes as per customer specifications.

Applications:

• Busbars and Electrical Conductors

• Power Distribution Systems

• Cable Lugs and Terminals

• Switchgear and Control Panels

• Transformer Connectors

• Heat Sinks and Thermal Interfaces

Advantages:

• Cost-effective alternative to solid copper sheets

• Ideal for current-carrying and contact surfaces

• Improved thermal management and conductivity

• Easy to machine, punch, and weld

• Long-lasting performance in indoor and outdoor installations
