In coastal or polluted industrial environments, moisture acts as an electrolyte, accelerating galvanic attack at the tube-fin contact interface. Furthermore, copper tubes are susceptible to formication corrosion caused by organic acid vapors.<\/p><\/li><li><p data-path-to-node=\"33,1,0\">MCHE Corrosion Mechanics: Constructed entirely from 100% aluminum alloy (typically 3000-series cores with 4000-series cladding), MCHE eliminates galvanic couples within the core.
