Copper-nickel and aluminum-nickel composite sheets have good conductivity and weldability, and are currently mainly used in the busbars of power battery packs.

Product Advantages:

(1) Safer and more reliable, no soldering required, no cold solder joints, fusible, integrated design, better earthquake resistance;

(2) High electrical conductivity, with a conductivity rate of 77%; the copper-nickel composite sheet is 3.3 times that of a pure nickel strip.

(3) High heat dissipation characteristics, significantly reducing battery heating. Under the same time and current, the copper-nickel composite strip reduces temperature by more than 20 degrees compared to pure nickel strip;

(4) Good welding performance, suitable for various types of single-pin resistance spot welding, ultrasonic welding, brazing, and other welding forms of busbars.
