Corrosion Resistance EN AW 5052 Aluminium Coil AA5052 Aluminium Coil

5052 aluminum is a versatile premium-grade material suitable for a wide range of applications.

Although the metal is not heat treatable, magnesium and chromium — the two most prevalent

alloying elements — significantly increase the aluminum’s strength, durability, and corrosion re

-sistance. The increased tensile strength and yield strength allows the alloy to handle high levels

of stress and stand up to the harshest of environmental conditions.
