53560301C - Nexalloy ER5356 Aluminum MIG Wire 0.030" - 5lb Spool

Professional Grade ER5356 Aluminum Alloy

The Nexalloy 5356 Aluminum MIG Wire is a premium filler metal designed for professional fabrication environments requiring high-strength structural welds. Classified as ER5356, this alloy contains approximately 5% magnesium, which serves as the primary alloying element. This composition provides the wire with significantly higher tensile and shear strength compared to the commonly used 4043 alloy. It is specifically engineered for welding 5XXX series base metals, including 5050, 5052, 5083, 5356, 5454, and 5456.

One of the defining characteristics of Nexalloy 5356 is its excellent corrosion resistance, particularly in saltwater environments. This makes it the industry standard for marine fabrication, including shipbuilding, boat hull repair, and offshore structures. The 0.030-inch diameter offered in this 5lb spool allows for precision welding on thinner gauge materials while maintaining the deposition rates necessary for efficient production. The wire's stiffness, a result of the magnesium content, enhances feedability through MIG guns and push-pull systems, reducing the likelihood of birdnesting often associated with softer aluminum wires.

Metallurgically, this wire is non-heat treatable but responds well to cold working. It has a melting range of 1060°F to 1175°F and typically produces a weld deposit with a density of approximately 0.096 lbs/cu.in. For applications requiring post-weld anodizing, Nexalloy 5356 is superior to 4043, as it anodizes to a white color that closely matches the base metal, whereas 4043 tends to turn gray or black. It is recommended for use with 100% Argon shielding gas or Argon/Helium mixtures for thicker sections.

Technical Specifications and Compliance

This product meets AWS A5.10 specifications for ER5356. It is suitable for all-position welding, provided the appropriate transfer mode (typically spray transfer or pulsed MIG) is utilized. The 5lb spool size is optimized for portability, fitting standard spool guns and smaller portable MIG welding units, ensuring fresh wire is available for specific jobs without the bulk of industrial drums.
