FIELD TESTING OF ALUMINUM BUMPER ALLOYS--TWO-YEAR REPORT

Tabulated data give progress of atmospheric exposure testing of bare, anodized, plated, and organic-coated aluminum bumper stock in the following environments: subtropical rural; mild marine; desert urban; mild industrial; and industrial. Corrosion rates after one year of exposure of the various aluminum alloys are compared with rates for such competitive metals as carbon steel, type 304 stainless steel, zinc, and galvanized steel. The subtropical environment is more severe than the desert in terms of corrosion rates, but the latter is more aggressive toward organic coatings. The industrial location is the most aggressive, followed by the semi-industrial location. Two anodized alloys had a new appearance at the desert and subtropical locations. Both bumper-stock samples and full-size bumpers were tested; the latter included chrome-plated, anodized, and organically coated aluminum bumpers, and chrome-plated steel bumpers.
