Product Description
EN AW-AlMg4.5Mn0.7(A) (S Al 5183A / EN ISO 18273) is a high-strength aluminum-magnesium-manganese filler metal supplied as continuous wire spools for MIG (GMAW) welding and cut rods for TIG (GTAW) welding.
In European designation standards (EN ISO 18273), the "(A)" suffix indicates a strictly controlled composition variant within the 5183 family. It features tighter limits on trace impurity elements (such as silicon and beryllium) to ensure consistent weld metal mechanical properties, low porosity, and high crack resistance when joining structural 5xxx-series aluminum alloys like EN AW-5083.

Key Applications and Operational Guidelines
-
Structural Marine & Cryogenics: Primary choice for shipbuilding hulls, offshore structures, pressure vessels, and LNG transport tanks due to high seawater corrosion resistance and excellent low-temperature toughness down to -196 degrees Celsius.
-
Base Metal Matching: Specifically engineered to match or exceed the mechanical properties of EN AW-5083 (AlMg4.5Mn0.7), EN AW-5086, and EN AW-5456.
-
Shielding Gas Recommendations:
Temperature Limit: Because the magnesium content exceeds 3.0 percent, welded joints made with AlMg4.5Mn0.7(A) should not be exposed to sustained service temperatures above 65 degrees Celsius (150 degrees Fahrenheit) due to risk of stress corrosion cracking (SCC).
