  • Method of producing a corrosion resistant aluminum heat exchanger
    Patent number: 8152047
    Abstract: An aluminum heat exchanger having increased resistance to galvanic corrosion. The exterior of one end of the aluminum tube or connector is coated with a metal or metal alloy. This end is brazed onto a copper or copper alloy inlet or outlet tube. The metal or metal alloy coating inhibits the formation of galvanic corrosion.
