Aluminium Alloy 3003 is a medium strength alloy with very good resistance to atmospheric corrosion and very good weldability as well as good cold formability. It has better mechanical properties, especially at elevated temperatures than the 1000 series alloys. All other characteristics viz appearance and applications are similar to Alloy 1100 stucco sheets. A stucco embossed finish is achieved by processing the natural mill finish material through embossing rollers. This provides a surface, which diffuses light reducing reflectivity and glare. It is used for applications on decorative effects, or to reduce surface reflectivity. As Aluminium is both a stable and durable material, it provides excellent service as a roofing or cladding without the need of any protective coating.
