Aluminum Tig Rod - ER5356
ER5356 aluminum TIG rod is the high-strength aluminum GTAW filler (AWS A5.10), an aluminum-magnesium (~5% Mg) alloy with higher tensile strength and excellent saltwater corrosion resistance. It color-matches anodized work and is the standard for marine, 5xxx-series, and structural aluminum. 36" cut lengths in 1/16", 3/32", and 1/8", under 100% argon on AC.

Frequently Asked Questions
Why is ER5356 the choice for marine aluminum?
Its magnesium content gives higher strength and strong resistance to saltwater corrosion, making it standard for boats and 5xxx-series marine structures.
ER5356 vs ER4043 for TIG strength?
ER5356 deposits a higher-strength weld; ER4043 is easier to run and more crack-resistant on 6xxx castings. Match the filler to your base alloy and strength needs.
