5052 aluminum sheet is often referred to as "Anodize Quality Aluminum", as it has excellent finishing qualities and anodized coatings are bright and clear. The major alloying element in 5052 is magnesium in sufficient quantities to cause substantial lowering of the melting point without producing brittleness. When magnesium is used as the major alloying element, or in combination with manganese, the result is a moderate to high strength non-heat treatable aluminum alloy. 5052 is far stronger than the 1100 or 3000 series aluminums, yet forms with reasonable bend radii. Weldability is very good and 5052 has good resistance to corrosion, especially in salt-water / marine atmospheres.
