A Conductive Black Finish?

I need help with our black zinc problem. We manufacture a product that uses black zinc plated CRS brackets to mount printed circuit boards. It seems the black zinc is not electrically conductive enough for our application. Is there an alternative? Right now we have been having the parts clear zinc'd and then mask and powder coat. We would like to find a solution that is more cost effective.

If conductivity is all you require you can think about copper plating with a black oxide coat and any conductive Silver plating anti-tarnish.
