The gold standard for automotive fastener protection, providing over 1000 hours of salt spray resistance.
Zinc-nickel alloy plating is the benchmark finish for automotive OEM fasteners and engine-bay components that must survive extreme temperature cycling and prolonged salt-spray exposure.
Our trivalent passivation process delivers over 1,000 hours of corrosion resistance while remaining fully RoHS and ELV compliant.
Advanced corrosion protection combined with thermal stability, environmental compliance and automotive-grade performance.
Industry-leading corrosion resistance validated to automotive OEM specifications.
Maintains protective performance in engine-bay temperatures up to 300°C.
Hexavalent-chromium-free chemistry meeting RoHS and ELV requirements.
Qualified to GMW3044 / VDA235-104 fastener specifications.
Degreasing and acid activation prepare fasteners for uniform deposition.
Alloy plating bath deposits a 12–16% nickel content zinc-nickel layer.
Chromate-free passivation boosts corrosion resistance further.
Hydrogen embrittlement relief baking followed by salt-spray and torque testing.
