For many years, until the advent of 5083 and 5086, this alloy was the highest strength non-heat-treatable alloy commercially available. Although easily welded, it is not recommended for brazing and soldering applications. Excellent corrosion resistance, particularly in marine applications. Adapts to most mechanical and finishing processes although the heavier anodic films may take on a yellowish cast. Fair machining with the proper set-up.
