Connection elements with a zinc-plated chromium(VI)-free zinc-nickel coating (ZNBHL black or ZNSHL silver) 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 hours against base metal corrosion in accordance with DIN EN ISO 9227 NSS
- Adjusted friction coefficient range from 0.09μ - 0.14μ due to top coat with integrated lubricating particles
- Thermal capacity up to 120°C
- Even coating distribution
- Functional and decorative
