Holmbury Zinc Nickel plated couplings complete 1200 hour salt spray test

Zinc Nickel data sheet v1 (HQ4)Holmbury Zinc Nickel plated couplings complete 1200 hour salt spray test without any signs of fatigue or red rust. Holmbury recently submitted a selection of their zinc nickel plated couplings for testing alongside several competitor solutions. The results were quite remarkable and proved beyond doubt that Holmbury offers the most effective corrosion protection currently on the market. Zinc nickel plating is available as standard on several of our product series and available as an option on many others. Please enquire for more details.

Salt Spray Test

A total of eight couplings, which included Holmbury zinc nickel and trivalent plated couplings, were submitted initially for 480 hours of salt spray exposure according to ASTM B117. All samples were exposed according to the instructions provided in ASTM B117, “Standard Procedure for Operating Salt Spray (Fog) Apparatus”. As the test reached its conclusion it became clear that the Holmbury zinc nickel plating would far exceed the 480 hour mark. The test was then continued in order to ascertain the failure point for the zinc nickel plated couplings.
