AK-ER5356 Al-Mg Alloy Wire for Welding 5xxx Series Alloys.
An Al-Mg alloy welding wire designed for high-strength, ductile welds with improved corrosion resistance and anodized color match in 5xxx series aluminum alloys.
Product Overview
AK-ER5356 is a solid aluminum-magnesium alloy welding wire used for joining 5xxx series aluminum alloys. It delivers higher weld strength and greater ductility compared to standard filler metals, making it suitable for structural applications under mechanical stress.
The wire has a chemical composition tailored for corrosion resistance in saltwater environments and a close color match to the base metal after anodizing. It is compatible with direct current reversed polarity (DCRP) and requires argon shielding gas for stable arc performance and clean welds.
AK-ER5356 is supplied to EN ISO 18273 S Al 5356, AWS A5.10 ER5356, and GB/T 10858 SAl 5356 classifications.
Application: Welding for 5xxx series alloys.
Key Benefits
High Strength and Ductility.
With a tensile strength of at least 105 MPa and yield stress of at least 205 MPa, AK-ER5356 provides robust welds in 5xxx series aluminum alloys where mechanical performance is critical.
Corrosion Resistance in Saltwater.
The alloy composition, particularly the magnesium content between 4.5% and 5.5%, enhances resistance to corrosion in marine and coastal environments.
Anodized Color Match
After anodizing, the weld metal achieves a color match close to the base metal, which is important for aesthetic and surface finish requirements.
Argon Shielding Required
The wire must be used with argon shielding gas to maintain arc stability, minimize oxidation, and ensure clean, high-quality welds.
Where It Is Used
- Welding of 5xxx series aluminum alloys in marine and offshore structures.
- Structural components in transportation and industrial equipment.
- Applications requiring high ductility and resistance to stress corrosion cracking.
- Fabrication where post-weld anodizing is performed.
Who It Is For
- Welding consumable distributors supplying aluminum welding materials.
- Fabricators working with 5xxx series aluminum alloys in demanding environments.
- Maintenance teams repairing aluminum structures exposed to saltwater.
Problems It Solves
- Achieving weld strength and ductility in 5xxx series aluminum alloys without compromising corrosion resistance.
- Matching the anodized color of the weld zone to the base metal after surface treatment.
- Ensuring consistent weld quality in saltwater-exposed structures using a filler metal with proven corrosion resistance.

Use Guide
- Use direct current reversed polarity (DCRP) for optimal arc stability and penetration.
- Shield the weld zone with pure argon gas to prevent oxidation and ensure clean weld metal.
- Clean the base metal surfaces thoroughly before welding to remove oil, grease, and oxide layers.
- Store the wire in sealed packaging to prevent moisture absorption and contamination.
How It Compares
AK-ER5356 is an Al-Mg alloy wire suitable for 5xxx series aluminum alloys. It differs from ER4043, which has higher silicon content and is used for lower-strength applications with better fluidity. ER5356 offers higher strength and better corrosion resistance in saltwater, while ER4043 is better for welding thin sections and non-structural joints. For applications requiring maximum ductility and strength, ER5356 is preferred over lower-magnesium alternatives.
