Galvanic anodes, when formed of alloys of commercial grade magnesium, aluminum and zinc, and which include misch metal, have been found to maintain efficiencies comparable with anodes of typical alloys made from the pure metals. The potential difference between a galvanic anode and its protected structur usually between 0.5 and 1.0 volt. Since these misch metal alloys have less tendency to form oxide layers, lower resistance to earth and, hence, greater effectiveness is maintained.
