This is the highest strength alloy of the more common non-heat-treatable grades. Fatigue strength is higher than most aluminium alloys. In addition, this grade has particularly good resistance to marine atmosphere and salt water corrosion. It has excellent workability. It may be drawn or formed into intricate shapes, and its slightly greater strength in the annealed condition minimises tearing that occurs in 1100 or 3003. The resistance welding characteristics are equal to those of 1100 or 3003. it has excellent finishing characteristiccs, and anodic coatings are bright and clear.
