CZ110 (CW702R)

CZ110 (CW702R) is a copper zinc alloy with additions of aluminium and arsenic, the latter being used as an inhibitor against dezincification. The presence of aluminium provides very good corrosion and erosion resistance in clean and slightly polluted waters, including seawater, either stagnant or relatively fast moving (up to about 3m/s).

CZ110 (CW702R) is specified in the oil and gas and shipbuilding industries for the manufacture of condensers, oil coolers and other heat exchangers used in aggressive conditions.
