Product Description
EN AW-5183A (S Al 5183A / AlMg4.5Mn0.7(A)) is a European standardized variant within the high-strength aluminum-magnesium-manganese filler metal group. It is formatted as continuous wire spools for MIG (GMAW) welding and cut rods for TIG (GTAW) welding.
The "A" suffix in European standards (EN ISO 18273) indicates minor tightened controls on trace impurity limits compared to older or alternative sub-variants (like 5183B or 5183C), ensuring reliable high-strength performance when welding 5xxx-series structural alloys like EN AW-5083.
