Description
Atomfair Electrolytic Nickel Foil – International Product Specification
Product Overview
Atomfair Electrolytic Nickel Foil is precision manufactured through advanced electrolytic processing using Grade 1 electrolytic nickel as the raw material. The product features a smooth, clean surface with excellent flatness, superior ductility, low impurity content, and high purity (nickel content ≥99%).
Its high purity delivers exceptional corrosion resistance and electromagnetic shielding performance. Compared with rolled nickel foil, it offers significantly wider width, greatly improving material utilization rate in post-processing. Customizable surface roughening treatment (Ra 1.5um or above) is available to enhance hydrophilicity, adhesion, and adsorption, ensuring firm bonding with other materials and preventing delamination.
