Product Description
Spot Welding Optimized Copper Nickel Busbar for Battery Pack & Industrial Power Links
1.Product Description
This annealed copper nickel busbar adopts electrolytic copper base matched with dense electroplated nickel coating, fabricated following unified domestic electrical alloy specifications. The composite layered construction balances ultra-high conductive efficiency and robust anti-oxidation capacity, delivering minimal contact impedance during continuous high-current transmission. Soft annealing treatment endows the strip outstanding bendability and consistent spot welding performance, free from plating peeling under frequent thermal cycling. Suited for humid tropical Southeast Asian installations, dusty Middle Eastern power facilities and temperate European energy storage assemblies, this conductive sheet supports personalized dimensional adjustments. Every finished piece undergoes multi-index physical and chemical testing to satisfy cross-border electrical assembly standards without extra surface modification.
