Non-conductive finish for BeCu alloys

What options are out there for applying non-conductive coatings to Cu / BeCu alloys? I have a connector application in which a very small and delicate BeCu spring element needs to be insulated from the component it is interacting with. Ideally the coating would have good wear resistance as the application would see several thousand insertion/extraction cycles. Also would prefer a process that could possibly be done or adapted to in an in-line or reel-to-reel process as with electrolytic plating processes.

Offhand it seems that a thin organic coating might not survive the insertion cycles and you might want to anodize the copper or plate it with aluminum and anodize the aluminum.
