Product Details

Copper Aluminum Bimetallic Transition Joint Busbar, T2 Copper+1060 Aluminum, Custom Thickness Width Length Processing

Core Material Specification：

Copper Layer: T2 electrolytic copper, high electrical conductivity ≥98% IACS, excellent ductility for bending & drilling
Aluminum Layer: 1060 pure aluminum, good corrosion resistance, lightweight & cost-effective
Bonding Technology: Explosion Bonded / Friction Welded (optional), tight molecular combination, no delamination under high current & temperature fluctuation

Key Product Advantages：

Low Contact Resistance: Metallurgical fusion bonding ensures stable conductivity, lower heat generation under rated load
Anti-Electrochemical Corrosion: Integrated bimetallic structure avoids copper-aluminum galvanic corrosion at joint position
Flexible Customization: Custom thickness, width, overall length, mounting hole size & hole spacing per customer drawings
Optional Surface Treatment: Tin plating / Nickel plating on copper side or full surface to improve oxidation resistance
Wide Temperature Adaptability: Stable performance from -40℃ to 120℃, suitable for indoor & outdoor power projects

Main Application Fields：

Power Distribution Cabinet, LV/MV switchgear
Distribution Transformer incoming & outgoing terminal transition
New Energy: Energy storage cabinet, EV charging pile, inverter, lithium battery connection
