"ELECTROLYSIS BETWEEN COPPER AND STAINLESS STEEL"
CAN ELECTROYSIS TAKE PLACE BETWEEN A COPPER DRAIN LINE AND A STAINLESS STEEL SURFACE? SURFACE IS THE WALL OF A WALK IN COOLER.NORMAN KECK

Galvanic corrosion (electrolysis) requires the presence of two different metals, a conductive (metallic) metallic path between them, and an ionic path (water or moisture connecting the two metals). If this drain line and stainless steel surface offer this combination, then electrolysis can occur. Generally the best way to stop it is to use plastic(hose, dielectric unions, spacers) in some way to break the conductive path between the two metals.

As a Window and Door Manufacturer, we are asked to do the seemingly impossible at times. Along the lines of Electrolysis, if a copper cladding is used on a Mahogany window (exterior), and secured with stainless steel screws and staples, what is the time frame that electrolysis would occur? What does this do to the integrity of the window and its finish?
Does this occur with aluminum as well? What other fastener or combination of metals are recommended in these applications.

I would like an explanation of what electrolysis would occur when copper flashing is used under adormer window that would be in contact with aluminum step flashing that goes up the side walls of the dormer. HELP PLEASEGarland Rigney
