Aluminum Rectangle Bar 6063 Anodized offers exceptional corrosion resistance, light weight, good formability, and slighly higher strength than 6063-T52, but half that of 6061. The anodized surface of this 6063 gives it a longer service life with minimal upkeep and maintainance, in addition to being visually attractive and non-toxic. 6063 anodized is typically used in applications where corrosion resistance and aesthetic are more important than strength, such as piping, furniture, architectural trim, and decorative applications.
