53561836C - Nexalloy ER5356 Aluminum TIG Welding Rods 1/8" (3.2mm) - 10lb Tube

Nexalloy 5356: The Professional's Choice for Strong Aluminum Welds

Upgrade your aluminum welding capabilities with Nexalloy 5356 TIG Rods. This 10lb tube of 1/8" (3.2mm) cut lengths is essential for any welder working with structural aluminum or projects requiring high ductility. Unlike the softer 4043 alloy, 5356 is a magnesium-alloyed aluminum that offers greater stiffness, making it easier to feed through the hand during TIG welding without bending or kinking excessively. It is the go-to filler metal for welding 5XXX series alloys and is an excellent alternative for 6XXX series alloys when strength is a priority.

Why Choose 5356 Over 4043?

While 4043 flows slightly wetter and minimizes crack sensitivity in some applications, 5356 is the clear winner for strength and toughness. It provides nearly double the shear strength of 4043, making it critical for fillet welds on structural components. If you are welding parts that will be subject to vibration or impact, the higher ductility of 5356 helps prevent failure. Furthermore, if your project involves anodizing, 5356 is mandatory to avoid the "black weld" effect seen with silicon-based fillers.

Optimized for Quality and Consistency

Nexalloy employs rigorous cleaning and processing standards to ensure their TIG rods are free from surface contaminants like oxides and oils. This attention to detail results in X-ray quality welds with minimal porosity. The 1/8" diameter is perfect for medium-to-thick base metals, allowing for good deposition rates while maintaining control over the puddle. Whether you are fabricating fuel tanks, truck bodies, or marine fittings, this filler metal delivers consistent bead appearance and mechanical integrity.

Application Tips

For best results, ensure your base material is thoroughly cleaned with a stainless steel wire brush dedicated solely to aluminum. Use 100% Argon shielding gas or an Argon/Helium mix for thicker sections to improve penetration. Because 5356 has a slightly lower melting range than the base metal but freezes faster than 4043, it allows for excellent control in out-of-position welding, including vertical and overhead passes.
