2008-1-20 However, you may want to consider using stainless steel fasteners. The rate of galvanic corrosion is related directly to the ratio of cathode area (stainless) to anode area (aluminum). In other words a relatively small anode area like an aluminum pop rivet will be attacked much faster than a large one like the 1/4" plate. Good luck.

Discolouration of stainless steel by corrosion products. Staining effects on stainless steels from corrosion products of the coupled metal can also be an issue. Lead and copper are quite close on the nobility table to stainless steel and so the bimetallic corrosion risks should be small.
Galvanic corrosion can occur when two dissimilar metallic materials are electrically connected in a corrosive environment. The less noble material will corrode. The corrosion rate is strongly dependent on the electric conductivity of the aggressive solution, the difference in corrosion potential between the galvanically coupled materials and the surface ratio between the electrodes.
