Material and composition: Manufactured from ER5356 aluminum alloy, these TIG filler rods contain approximately 4.5–5.5% magnesium. The alloy balance provides a good combination of strength and ductility, making it suitable for joining aluminum-magnesium, aluminum-magnesium-zinc, and aluminum-silicon-magnesium families.

Size and packaging: Each rod measures 3/32 inch in diameter and 39 inches long. The set is supplied as a 15 lb pack, intended to supply continuous work on medium to large projects and reduce downtime from frequent repacking.

Performance and environment: With the specified magnesium content, these rods are formulated to resist corrosion in saltwater and other aggressive environments, which makes them appropriate for shipbuilding, pressure vessel fabrication, and other marine applications. They produce a clean, bright bead with minimal spatter when run correctly.

Welding parameters and compatibility: For optimal results use 100% argon shielding gas and direct current electrode positive (DCEP). These rods perform well on 6xxx-series alloys such as 6061 and on many magnesium-bearing aluminum mixes; they offer excellent arc stability for TIG welding processes.

Storage and handling: The 15 lb supply is convenient for extended operations; however, unused rods should be kept sealed and stored in a dry place to prevent surface oxidation or contamination. Their length may require longer filler rod storage tubes or racks designed for 39-inch pieces.

VerdictThese ER5356 TIG rods deliver stable arcs and attractive, low-spatter welds for aluminum-magnesium and related alloys. The 15 lb quantity is convenient for medium-to-large jobs, and the Mg content provides solid resistance to marine corrosion. Best suited for users prepared to run 100% argon and DCEP and who can accommodate the 39-inch rod length.

This guy 5/5

Smooth, predictable welding

Welded thin-wall intercooler tubing with these rods and had a very steady arc. They laid down nicely and I still have plenty left for future jobs.

Betty Baumgarten 5/5

Solid quality

Good material and consistent performance for general TIG work.

Zach W. 5/5

Perfect for small boat repairs

Worked well when TIG welding mounting pods and reattaching sections on my jon boat.

Efrain Munoz 5/5

Very high quality

Top quality and reliable for aluminum TIG work.

Matthew E. Johnson 5/5

Long rods, good on 6061

Welds 6061 cleanly but the 39-inch length won't fit shorter filler rod holders. Excellent quantity for workshop use.
