Aluminium ENAW-5183A Welding Wire Rod(TIG, MIG,Filler Metal)

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.

Chemical Composition (EN ISO 18273: S Al 5183A)

• Magnesium (Mg): 4.30 to 5.20 percent

• Manganese (Mn): 0.50 to 1.00 percent

• Chromium (Cr): 0.05 to 0.25 percent

• Titanium (Ti): 0.15 percent maximum

• Iron (Fe): 0.40 percent maximum

• Silicon (Si): 0.25 to 0.40 percent maximum

• Zinc (Zn): 0.25 percent maximum

• Copper (Cu): 0.10 percent maximum

• Beryllium (Be): 0.0003 percent maximum

• Aluminum (Al): Balance

Key Mechanical and Physical Properties (As-Welded)

• Tensile Strength: 275 MPa minimum (40 ksi)

• Yield Strength: 130 MPa minimum (19 ksi)

• Elongation: 17 percent minimum

• Melting Range: 574 to 638 degrees Celsius

• Density: 2.66 g/cm³

• Anodizing Match: High aesthetic consistency (white/silver color match) with 5xxx-series base metals.

Key Characteristics and Applications

• High Structural Strength: High manganese content provides solid-solution strengthening, allowing welded joints on EN AW-5083 plate to reliably hit 275 MPa minimum tensile requirements.

• Marine and Marine-Offshore: Superior resistance to seawater corrosion and pitting in harsh marine environments.

• Cryogenic Applications: Excellent impact toughness and mechanical ductility at temperatures down to -196 degrees Celsius (liquid nitrogen/LNG containment).

• Primary Compatible Base Materials: EN AW-5083, EN AW-5086, EN AW-5456, EN AW-7039.

Temperature Limitation: Like all Al-Mg filler metals with over 3.0 percent Magnesium, welds made with EN AW-5183A are susceptible to intergranular stress corrosion cracking (SCC) if subjected to sustained service temperatures above 65 degrees Celsius (150 degrees Fahrenheit).
