Aluminum heat exchangers are subject to a wide range of severe environmental conditions, e.g. de-icing road salt, grit, acid exhaust fumes, etc. The heat exchanger can be protected against aggressive external and internal corrosion attacks using the principle of galvanic protection for critical compo-nents and through suitable alloy selection.

A less noble (anodic) alloy will corrode preferentially to a noble (cathodic) alloy when in contact via a corrosive medium. This principle can be applied to the individual components of a heat exchanger (e.g. tubes, headers, tanks, etc.), and it can also be applied to the heat exchanger alloy system itself.

WE CAN ADVISE YOU FURTHER ON ALLOY SELECTION AND COMPATIBILTIY, IF REQUIRED.

In addition to the galvanic protection principle, the micro-structure of Aleris’ brazing alloys have been engineered to improve their corrosion life. This alloy development process is ongoing through our continuous R&D activities, and has to date produced a series of “Long-Life” alloys, and more recently multiclad materials.

CORROSION PROTECTION

www.aleris.com 11

1ST GENERATION LONG-LIFE ALLOYS

The special chemical compositions and thermo-mechanical processing of these alloys (e.g. Hogal 3190, 3532, 3534, 3542), have been designed by Aleris to give both high corrosion performance and high strength. On brazing Si diffuses from the clad into the core, where small particles of α-Al(MnFe)Si precipitate along the clad / core interface, this band has a corrosion potential lower than the core and acts to sacrifi cially protect it against external corrosion penetrating through the material depth. In H24 temper these alloys have elongated grains after brazing, which are also advantageous for corrosion, as they create longer grain boundaries compared to other material tempers.

2ND GENERATION AGE HARDENING / HIGH STRENGTH

The use of Cu in these alloys (e.g. Hogal 3572, 3536) creates an additional corrosion protection mechanism in these material, after brazing a Cu depleted band, which is less noble compared to the core material also protects against external corrosion penetrating through the material.

3RD GENERATION “ECO” ALLOYS

Our latest generation of alloys (e.g. Hogal 3551 and 3527) have been designed to provide an economically optimized solution between the performance of the 2nd generation alloys and the cost of the 1st generation alloys. This has been achieved by enhancing the chemistry of these materials to make them both more cost effective and environmentally friendly, as they can require less primary (pure) aluminum in their initial processing.
