Aluminum Copper Bimetal Clad Strips

Key Advantages & Features:
⚡ Electrochemical Corrosion Resistance

Proprietary bonding technology neutralizes galvanic potential differences, preventing oxidation (Al₂O₃ formation) and ensuring safe electrical transitions.
Ideal for humid, high-current environments where pure copper or aluminum alone would degrade.

⚡ Dual Performance Excellence

High Electrical Conductivity: Copper layer ensures efficient current transfer (up to 85% IACS).
Superior Thermal Dissipation: Aluminum layer rapidly disperses heat, reducing hotspots.

⚡ Lightweight & Cost-Effective

50-70% lighter than pure copper, slashing material and logistics costs.
Strategic copper placement optimizes conductivity without full copper weight.

Applications:
🔌 Energy & Automotive:

EV Battery Systems: Cell tabs (soft-pack battery ears), cell interconnects, module busbars, terminal connectors.
Power Distribution: Transformer/reactor busbars, cable joints, bus ducts, switchgear shunts.
Renewable Energy: Solar inverter links, battery storage interconnects.

🔌 Electronics & Industrial:

High-Power LED: Heat sinks, thermally conductive substrates, PCB baseplates.
Electrolysis Plants: Corrosion-resistant anode/cathode connectors.
Decorative Architecture: Lightweight façade panels, copper-aluminum composite decor (windows, cutlery).
