Connection elements with a galvanised chromium (VI)-free zinc-nickel coating are suitable for applications with a high risk of corrosion. The coating comprises a zinc-nickel alloy layer and a sealing coat (top coat with integrated lubricating particles).
Overview of advantages:
- Corrosion resistance of up to 720 hrs to base metal corrosion in accordance with DIN EN ISO 9227 NSS
- Adjusted friction coefficient range of 0.12 μ–0.18 μ due to top coat with integrated lubricating particles, thermal capacity up to 120°C
- Even coat distribution
- Functional and decorative
