ESAB OK Autrod 5356: The Industry Standard for Aluminum Welding

The ESAB OK Autrod 5356 is a premium quality aluminum-magnesium alloy (AlMg5) MIG welding wire designed for general-purpose welding of 5XXX series alloys. As the most widely used aluminum welding alloy in the industry, it is favored for its excellent balance of strength, corrosion resistance, and workability. This 9.07 kg (20 lb) spool comes in a 1/16-inch (1.6 mm) diameter, suitable for heavy-duty industrial fabrication where high deposition rates are required.

OK Autrod 5356 is typically chosen over 4043 alloys when higher shear strength is required. The 5% magnesium content provides superior mechanical properties, making it the filler metal of choice for structural applications. It is compatible with base materials such as 5050, 5052, 5083, 5356, 5454, and 5456. Additionally, this alloy offers a good color match with the base metal after anodizing, unlike 4043 which turns dark gray.

Technical Considerations: While OK Autrod 5356 is highly versatile, it is important to note that 5XXX series alloys with a weld pool chemistry greater than 3% Magnesium are susceptible to stress corrosion cracking if exposed to service temperatures in excess of 65°C (150°F). For high-temperature applications, alternative alloys may be required. This alloy is non-heat treatable.

ESAB's precision winding technology ensures consistent wire feeding, minimizing arc instability and contact tip burn-back. Whether for tank fabrication, architectural structures, or general repair, the OK Autrod 5356 delivers reliable, high-quality welds.
