1050A

Classed as being a non heat treatable, commercially pure grade, 1050 has a 99.5% aluminium content and is noted for its excellent cold formability, corrosion resistance and aesthetic qualities. Grade 1050 is the most commonly used Aluminium for general sheet metal work where strength is not essential. 

The corrosion resistance of 1050 Aluminium means it can be utilised in many different atmospheres including industrial and marine environments. These factors combined with a capability for a highly polished finish, the ability to be formed easily via bending or spinning and excellent anodising and joining properties are behind its popularity in the marketplace.
