AA 5052 H38 Aluminum Alloy – Superior Corrosion Resistance & Welding

Aluminum AA 5052 is a non-heat treatable alloy with excellent finishing qualities. AA 5052 offers better corrosion resistance than most aluminum alloys, especially to salt water and marine atmospheres. This alloy can be readily welded using most common techniques and is in fact offers some of the best welding characteristics of all aluminum alloys.
