Plating copper buss bars
+++
I am a process engineer for a company that produces energy
controls and surge protection devices. We are designing a series of
copper buss bars to be used in one of our applications. The copper
bar is 0.375" wide x 0.125" thickness consisting of various lengths.
I am looking for a relatively inexpensive method for protecting these
from corrosion. Our plating vendor suggested yellow chromate while a
fellow engineer suggested bright dipping them. Are there any other
reasonable methods I should look into?

BRIGHT DIPS PROVIDE VERY LITTLE CORROSION PROTECTION. YELLOW
CHROMATE IS VERY GOOD. SOME NICKEL PLATE COPPER BUSS BARS FOR
CORROSION PROTECTION.
