Seeking Instrument to measure silver plating thickness on copper


I am looking for an instrument that will measure the silver plating thickness on a .059 copper wire. The plating thickness is .005" and the form is a spring

I would recommend x-ray Fluorescence.

Are you sure your plating is 0.005" thick and not 0.0005" thick? At 0.005" that is 5 mils thick. I doubt that X-ray fluorescence can measure silver that thick on your part. It is true that on small diameter wire XRF is the best method but not at 5 mils of Ag thickness. Can you please verify this?
