535611636C - Nexalloy ER5356 Aluminum TIG Welding Rod 1/16" x 36" (10lb Tube)

Premium Marine-Grade Aluminum Filler Metal

The Nexalloy 5356 TIG Rod is a high-performance aluminum filler metal designed to meet the rigorous demands of industrial and marine fabrication. Classified as an ER5356 alloy, this product is primarily composed of aluminum with a 5% magnesium addition, but Nexalloy distinguishes its formulation through a precise metallurgical balance. This specific blend includes elevated levels of manganese, magnesium, and titanium, alongside the strategic addition of chromium and a controlled reduction in silicon. This advanced chemistry serves to significantly enhance the mechanical properties of the weld deposit, specifically targeting grain refinement and corrosion resistance.

Metallurgical Superiority

The inclusion of titanium in the Nexalloy 5356 acts as a potent grain refiner, which improves the ductility and toughness of the weld metal. This is critical in structural applications where dynamic loads and vibration are factors. Furthermore, the addition of chromium, combined with the high magnesium content, creates a microstructure that is exceptionally resistant to the corrosive effects of saltwater and harsh atmospheric conditions. Unlike standard 5356 alloys, Nexalloy’s proprietary composition ensures that the filler metal not only meets but exceeds standard performance expectations in saline environments, making it the premier choice for shipbuilding, offshore platforms, and coastal infrastructure.

Application & Compatibility

This 1/16" (1.6mm) diameter rod is ideal for precision TIG welding on thin-to-medium gauge materials. It is the recommended filler metal for welding 5000-series base alloys such as 5050, 5052, 5083, 5086, 5454, and 5456. It is also compatible with 6000-series alloys (like 6061) when high tensile strength is prioritized over crack sensitivity, or when the part will not be subjected to post-weld heat treatment. The 10lb tube packaging ensures a substantial supply for production environments while protecting the rods from atmospheric moisture and contamination.

Technical Specifications

With a typical tensile strength ranging between 38,000 and 40,000 PSI, Nexalloy 5356 provides nearly double the shear strength of 4043 filler metals. It exhibits a melting range of 1060°F to 1175°F and requires proper cleaning of the base metal—specifically the removal of oxide layers—to ensure defect-free welds. The rod feeds smoothly and produces a deposit that closely matches the color of the base metal after anodizing, avoiding the dark gray discoloration often associated with high-silicon fillers.
