High-Performance Aluminum Copper Bimetal – Precision Bonding for Superior Thermal & Electrical Conductivity

Unlock the power of hybrid engineering with our Aluminum Copper Bimetal solutions, designed to deliver unmatched heat dissipation, electrical efficiency, and structural integrity in demanding applications. By seamlessly bonding lightweight aluminum with high-conductivity copper, we create a material that outperforms traditional metals, reducing energy loss and extending component lifespan.

Key Features:
⚡ Optimized Conductivity: Combines copper’s exceptional electrical/thermal properties with aluminum’s lightweight corrosion resistance.
⚡ Durable Clad Bonding: Explosion-welded or rolled-bonded interface ensures zero delamination under extreme temperatures (-200°C to 300°C).
⚡ Custom Geometry: Tailor thickness ratios (Al:Cu from 1:1 to 10:1), shapes, and surface finishes for your application.
⚡ Corrosion Resistance: Aluminum layer protects copper core from oxidation in harsh environments.
⚡ Cost Efficiency: Reduce material costs by strategically using copper only where conductivity is critical.

Applications:

• Power electronics (IGBT modules, busbars, inverters)

• EV battery terminals and charging connectors

• Heat sinks for high-power LEDs and semiconductor devices

• Solar panel junction boxes and transformer components

• HVAC heat exchangers and refrigeration systems
