EN 573-3 Grade 3.3523 H112 Aluminum Alloy – Superior Corrosion Resistance & Welding

Aluminum DIN 3.3523 is a non-heat treatable alloy with excellent finishing qualities. DIN 3.3523 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.
