Anti-tarnish for stain free copper plated surface on CRS?
Hi,
many copper components are replaced by copper plated steel components in most of electrical applications like contactors, circuit breakers, etc..
But it has become a tough task to get stain free copper plated surface. Coating thickness is 5 ~ 10 microns.
Any good anti tarnish to meet this.
The process: Cold Rolled steel coils - stamped - Alkaline copper plated(barrel) - Anti tarnish coated - Centrifugal Air drying
Many thanks in advance for your help

Many people use benzotriazole ⇦this on eBay or Amazon [affil links] as an antitarnish/ corrosion inhibitor for copper and copper alloys. You should be able to find a local supplier.
