5052 Aluminium Alloy Coil For Decoration Construction Roofing Industry

Aluminium metal has an appearance ranging from silvery white to dull gray, depending on the surface roughness.[d] Aluminium mirrors are the most reflective of all metal mirrors for the near ultraviolet and far infrared light, and one of the most reflective in the visible spectrum, nearly on par with silver, and the two therefore look similar. Aluminium is also good at reflecting solar radiation, although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized, which adds a protective layer of oxide on the surface.

As explained previously, aluminum alloys have specific percentages of alloying elements that improve material properties; these percentages are important, because they differentiate one alloy from another, especially within the same series. Type 5052 aluminum contains 97.25% Al, 2.5%Mg, and 0.25%Cr, and its density is 2.68 g/cm3 (0.0968 lb/in3). Generally, 5052 aluminum alloy is stronger than other popular alloys such as 3003 aluminum and also has improved corrosion resistance due to the absence of copper in its composition.
