Nickel 200 Foil Description
1) Introduction
Nickel 200 Foil (Ni200 / UNS N02200) is an ultra-thin nickel strip produced through multi-pass precision rolling from high-purity industrial nickel (Ni ≥ 99.6%–99.9%). As a commercially pure nickel material, it combines excellent electrical conductivity with strong corrosion resistance and stable processing performance.
Compared with titanium foils and other metal foils, Nickel 200 Foil delivers significantly higher electrical conductivity and better chemical stability. It performs especially well in alkaline and mildly reducing environments, making it more suitable for electrical and electrochemical applications where stable current transfer is required.
In engineering applications, different metal foils serve distinct roles based on their performance:
- Gr1 / Gr2 Titanium Foil offers low density and strong corrosion resistance, but relatively low electrical conductivity.
- Gr4 Titanium Foil provides higher strength, making it suitable for structural components.
- Gr5 Titanium Foil delivers high strength and excellent load-bearing capacity for high-stress applications.
- Nickel 200 Foil delivers high electrical conductivity and excellent chemical stability, making it suitable for electrical connections, electrodes, and chemical corrosion protection applications.
2) Standard specification:
- Thickness 0.03–0.8 mm, width 350–670 mm, suitable for industrial applications that require electrical conductivity, mechanical strength, and long-term stability.
- Custom thickness: 0.01–0.03 mm, suitable for common industrial conductive structures.
- Custom thickness: 0.005–0.01 mm, suitable for high-end precision and miniaturized applications.
3) Production Process & Equipment
