The difference between tin-plating and silver-flashing?

My company uses copper bus bar in its process. We manufacture medium voltage motor starters and motor controllers. This bus bar must be plated. We have used both tin-plating and silver-flashing. My question is; a)Which is better for both corrosion-resistance and electrical conductivity, tin plating or silver flashing? Also, b) How can the two be identified? Is there an easy method of determining which bus bars are silver-flashed and which are tin-plated?

Tin and silver have previously been compared for a similar application in letter 10574. As for a simple way to tell one from the other, though, I'd like to hear that answer myself.

Mr. Doyle,

Silver Flashing provides better corrosion resistance.
