Carbon has a galvanic reaction with most metals. 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.

I heard somewhere (wan't remember where) that carbon fiber and aluminum react to
each other. Can anyone confirm/deny this? If so, does carbon fiber react to
other metals (steel, stainless, brass etc) too?
