Aluminum Wire
ER5556 Aluminum Welding Wire
ER5556 (AlMg5.2Mn) is high-magnesium aluminum-manganese filler wire for welding 5xxx aluminum-magnesium alloys.
产品名称 ER5556
ALUMINUM WELDING WIRE (MIG & TIG)
ER5556 (AlMg5.2Mn) is high-magnesium aluminum-manganese filler wire for welding 5xxx aluminum-magnesium alloys.
Key Features: Higher magnesium content than ER5356 for improved strength, outstanding seawater corrosion resistance.
Caution: Unsuitable for long-term continuous high-temperature operation due to risk of stress corrosion cracking.
Applicable Standards
AWS A5.10：ER5556（MIG）/ R5556（TIG）
EN ISO 18273：S Al 5556（AlMg5.2Mn）
Standard Diameter & Packaging
• MIG wires: 0.8/0.9/1.0/1.2/1.6 mm, Standard spools: 0.45kg, 0.5kg, 1kg, 2kg,6 kg, 7 kg
-TIG rods: 2.0/2.4/3.2/4.0/5.0 mm, 1m fixed length, packed in5kg plastic tube and 5kg cardboard box.

Melting Range: 580–640℃
Key Advantages
• Alternative wire for 5083, 5086, 5456 high Mg 5xxx Al Mg alloys
• Higher deposited strength than ER5356 for high strength 5xxx structures
• Excellent seawater & chloride resistance for marine and salt spray applications
• Uniform white surface after anodizing, suitable for aesthetic parts
• Works with MIG and TIG; stable arc, low spatter
• Good ductility and smooth weld bead
Recommended Base Metals
✅ Recommended: 5083, 5086, 5456, 5254 Al-Mg alloys
✅ Dissimilar welding: 5xxx high-Mg alloys ↔ 6061/6082 Al-Mg-Si alloys
⚠️ Caution: Not for 5454 (ER5554 preferred); avoid cast aluminum
❌ Do not mix with 4xxx Al-Si wires (ER4043/ER4047) for 5-series aluminum Important Note: Long-term service over 65℃ may cause stress corrosion cracking; use ER5554 for high-temperature conditions.
Applications
· Ship structures, yachts and offshore aluminum constructions
· Port equipment and seawater desalination aluminum parts
