Title: ALUMINUM ALLOY MATERIAL WITH HEAT-CURED COATING HAVING EXCELLENT DURABILITY AND PRODUCTION METHOD THEREFOR
Abstract:
This 6000-series aluminum alloy material has a heat-cured coating on the surface thereof and has a specific composition. As a result of a heat-curing treatment for the heat-cured coating, Mg oxide is present in a specific range on the aluminum alloy material surface under the heat-cured coating, thereby improving coating durability such as filiform corrosion resistance, coating adhesion.
