Copper Aluminium Bimetal Sheet

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
