Pure Nickel Foil Strip 0.01-0.05mm Ni200 for Battery Connector and Flexible Circuit Applications

Pure Nickel Foil / Strip (N4 · N6 / Ni200 · Ni201)

1. Product Overview

Pure nickel foil and strip are produced from high-purity electrolytic nickel through vacuum melting, precision rolling and bright annealing. They feature high purity, excellent electrical and thermal conductivity, superior corrosion resistance and outstanding weldability. Thickness ranges from 0.001 mm (1 micron) up to 2.0 mm with customized width, offering consistent gauge, bright oxide-free surface and stable mechanical properties across the whole coil.
