Eagle ER5356 Aluminum MIG Wire | High-Strength Aluminum Welding Wire

Eagle ER5356 is recommended for:

Marine fabrication
Structural aluminum
Aluminum trailers
Transportation equipment
Tanks and vessels
Heavy aluminum fabrication
5050 aluminum
5052 aluminum
5083 aluminum
5454 aluminum
5456 aluminum
6061 aluminum
General aluminum repair
Production MIG welding

Especially well suited where strength, ductility, corrosion resistance and salt-water performance are important.

Clean the weld area thoroughly before welding.
Remove all oil, grease, lubricants, coatings, dirt and oxide from the aluminum surface.

Use a dedicated stainless steel wire brush for oxide removal and keep the brush reserved for aluminum only to avoid contamination.

Use 100% Argon shielding gas for typical MIG applications.
Operate on DC Reverse [+] / DCEP polarity.

Use proper aluminum wire-feeding equipment, including a suitable liner, drive-roll setup, spool gun or push-pull system where required.

Adjust voltage, amperage and travel speed according to material thickness, joint design and welding position.

Eagle ER5356 is an aluminum-magnesium filler wire containing approximately 5% magnesium.

Its magnesium content provides higher mechanical strength than many general-purpose aluminum filler wires while maintaining excellent ductility and corrosion resistance.

ER5356 is particularly well known for its performance in marine and salt-water environments.

The weld deposit also provides a white colour after anodizing, which can make ER5356 preferable where the welded component will be anodized after fabrication.

Why Eagle ER5356?

Higher-strength aluminum filler — a strong choice for structural and demanding aluminum fabrication.

Excellent corrosion resistance — performs especially well in marine and salt-water environments.

Good ductility — provides a strong yet workable weld deposit.

Excellent for 5XXX-series aluminum — commonly used on alloys such as 5052, 5083, 5454 and 5456.

Suitable for 6061 — a useful option where higher strength or better anodized colour match is preferred.

Good anodized colour match — the weld area remains much closer to white after anodizing than many silicon-based fillers.

ER5356 or ER4043?

Choose Eagle ER5356 when higher strength, better ductility, marine corrosion resistance or better anodized colour match are important.

Choose Eagle ER4043 when you want excellent fluidity, easier puddle control and reduced crack sensitivity, especially for general fabrication and cast aluminum applications.

In simple terms:
ER5356 = stronger aluminum-magnesium wire for structural and marine work
ER4043 = smooth-flowing general-purpose aluminum-silicon wire
