Zinc Nickel Process

Zinc Nickel

Zinc nickel plating provides over 1,00 hours of salt spray protection. Our RoHS compliant zinc nickel exceeds the corrosion protection of zinc and cadmium plating and out-performs conventional zinc plating. In today’s industrial finishing industry there are higher standards and requirements for corrosion resistance, and we help you meet or exceed these standards. Our zinc nickel finishing process produces a zinc nickel alloy chromate film that is rich in nickel, which increases the corrosion resistance of zinc nickel.

AFT’s zinc nickel is the perfect alternative to conventional zinc for any steel part that is intended for exterior use. Zinc nickel provides the most economical corrosion protection available today.

AFT Corp's zinc nickel plating process is RoHS compliant. AFT specializes in 16 metal plating processes including zinc nickel.

ADVANTAGES

High thermal resistance (up to 200˚C) makes it suitable for high temperature automotive applications
WEEE, ROHS and EVL compliant trivalent passivation (Chrome 6 Free)
Provides Superior Corrosion Resistance – protects the base metal for over 1000 hours to red rust
Around four times the hardness and therefore wear resistance of standard Zinc plating
Many of these features make Zinc-Nickel and environmentally friendly alternative for Cadmium plating

SALT SPRAY TESTING

Sample Description: Zinc-Nickel plated steel panel - ZnNi/TriPass ELV 3000 chromate/HydroKlad sealer (ASTM F1941-10 FE ZN Ni 8TF)

Summary:

One (1) sample was tested for Neutral Salt Spray (Fog) Testing (NSS Test) per ASTM B117-16

One (1) sample was exposed to 960 hours of continuous NSS testing

Preventative Maintenance / Calibration on this unit was completed on September 2016 and is next due by September 2017.

Completion Date: February 13, 2017

Method: ASTM B117

WB=White Blush; WC=White Corrosion; RR=Red Rust

Test: 384 Hours of Continuous NSS (Neutral Salt Spray) testing on both Zinc Nickel (ZnNi) and Cadmium (Cd) plated rings.

Result: Zinc Nickel outperformed the cadmium plated rings. No white corrosion is present on any of the zinc nickel plated samples.
