Nickel Plated Copper Aluminium Transition Busbar for New Energy Battery

Nickel Plated Cu-Al Bimetallic Transition Busbar is metallurgically composited with T2 copper and 1060 aluminum by explosion welding or friction welding. Full or partial nickel plating on copper surface greatly improves oxidation resistance, corrosion resistance and high-temperature stability.

Designed specially for new energy battery system to realize safe transition connection between copper and aluminum conductors, effectively avoid electrochemical corrosion caused by direct copper-aluminum contact.

All dimensions, hole layout and plating range support OEM customized production.
