High Composite Strength Copper Nickel Strip For Lithium Batteries

Copper nickel composite strip Purpose: the copper-nickel composite strip is mainly used in lithium batteries and flexible packaging battery connectors, with good weldability (can be used for transition welding). The application of our company's unique production technology, effectively avoid all kinds of shortcomings of the previous process, strip smooth and smooth, strip without layering, crack, peeling, bubble. New energy automobile battery pole ear special, continuous electroplating flexible nickel, high strength coating, stamping resistance, continuous bending coating does not fall off. Product features: patented technology, the first in China, using large strip continuous rolling and online bright annealing process, stable product quality. High composite strength, multi-pass rolling under high pressure, cu-ni can be completely tightly combined, can not peel, really achieve cu-ni composite Copper nickel plating product description: - Ni Plating process: electroless nickel Plating - Width: 2~100mm customizable - Thickness customizable: 0.08t ~ 0.4t - nickel Plating: 2 sides nickel Plating /4 sides nickel Plating - Edge treatment: as required by the customer - Surface treatment: according to customer requirements Test indicators: - Width tolerance: 4~100mm±0.3mm - Thickness tolerance :0.1~0.5mm±0.03mm - Edge: 0.07mm~0.22mm Plating-Nickel :0.5~1.5 m Bending Test: more than 180 degrees - soak Test: (Dipping Test) : constant temperature 85 ℃, 0.1% water, 24 h / 48 h off the coating.
