Carbon is at the top of the galvanic scale and aluminum is fairly near the bottom. In general, the farther apart the more there is a problem. A lot also depends on the environment. If the carbon is electrically isolated from the metal there is no problem. So metals like stainless that form a thin poor conducting oxide tend to have less of a problem. Normally you just use one thin ply of glass between the metal and the carbon and the problem is prevented. They also make coated fasteners for use with carbon.

Can anyone confirm/deny this? If so, does carbon fiber react to other metals (steel, stainless, brass etc) too?
