Abstract
Aluminum alloys have been employed in automobiles for some time in applications such as pistons. In recent years, however, increased use of aluminum alloys for many other automotive applications has been anticipated. This paper presents the available information on the resistance to corrosion of aluminum alloys for these many new uses. Particular emphasis has been placed on performance of aluminum alloys for automotive trim, but other applications are also covered. Included is a discussion of choice of alloy and the performance of the large variety of finishes available. Results of atmospheric corrosion tests together with those of limited field experience are provided to indicate the good resistance to corrosion of aluminum alloys in these applications. Factors affecting the performance of these alloys in service are also covered. 6.4.2
