Best Plating to Inhibit Welding

Best Plating to Inhibit Welding

Best Plating to Inhibit Welding

(OP)
I have two small brass parts that are being used in a switching device. Current is about 5 amps for 30 milliseconds. When the parts are unplated I can get a very slight welding action as witness under a scope. Worst case is the parts stick together due to the minute weld. Can anyone suggest a plating material and thickness for both parts that would be the best guard againt the parts welding together.

RE: Best Plating to Inhibit Welding

There are silver alloys for exactly this application. I forget their names though. Try electrical contact alloys as a google search. They commonly are added to the structural component as pads or buttons.
