OVERVIEW

Premium Grade Aluminum TIG Filler Metal

The ESAB OK Tigrod 5356 is a high-quality, general-purpose aluminum welding alloy designed for the Gas Tungsten Arc Welding (GTAW) process. Composed of 5% Magnesium (AlMg5), this filler metal is the industry standard for welding 5000-series aluminum alloys and is widely utilized for its superior mechanical properties. With a diameter of 4.0mm, this specific rod is engineered for heavy-duty applications requiring higher heat input and substantial deposition rates, making it suitable for welding thicker sections of plate and structural components.

Technical Performance and Metallurgy

One of the primary advantages of the OK Tigrod 5356 is its relatively high shear strength compared to silicon-based alloys like 4043. This makes it the preferred choice for structural applications where mechanical integrity is paramount. The alloy exhibits excellent corrosion resistance, particularly in saltwater environments, which establishes it as a staple in the marine industry for shipbuilding and repair. Furthermore, unlike 4043 which turns dark gray after anodizing, the 5356 alloy maintains a bright, white color match, ensuring an aesthetically pleasing finish on anodized parts.

Applications and Compatibility

This filler metal is highly versatile and compatible with a broad range of base materials, including 5050, 5052, 5083, 5356, 5454, and 5456. It is also compatible with 6000-series alloys (such as 6061-T6) and 7000-series alloys where post-weld heat treatment is not required. The 4.0mm diameter provides the welder with the ability to bridge larger gaps and build up welds efficiently on heavy-wall pipes, pressure vessels, and automotive frames. Packaged in a robust 5kg tube, the rods are protected from environmental contaminants, ensuring clean, porosity-free welds every time.

Industry Standards

ESAB maintains rigorous quality control standards. The OK Tigrod 5356 meets AWS A5.10 classifications for ER5356, ensuring consistent chemistry and performance. It is approved by major international bodies including CWB, ABS, and VdTÜV, validating its reliability for critical industrial projects.

FAQ

5356 (AlMg5) contains magnesium, offering higher shear strength and better color match after anodizing compared to 4043. 4043 (AlSi5) contains silicon, which makes it flow wetter and minimizes cracking, but it anodizes to a dark gray color.

100% Argon is the standard shielding gas for TIG welding with this rod. For thicker sections (like those requiring this 4.0mm rod), an Argon/Helium mixture can be used to increase heat input and penetration.

Yes, ER5356 is commonly used to weld 6061 base metals. It provides higher strength than 4043, though 4043 is sometimes preferred if the part will be heat-treated after welding or if crack sensitivity is a major concern.

Absolutely. The 5356 alloy has excellent corrosion resistance, specifically against saltwater, making it the standard choice for marine fabrication and boat repairs.

This product (SKU 181540R15A) has a diameter of 4.0mm, which is a larger diameter suitable for welding thicker base materials.

Aluminum TIG welding is almost exclusively done using AC (Alternating Current) to provide the necessary cleaning action to break up the aluminum oxide layer.

Store them in a cool, dry place, preferably in their original closed tube. Aluminum is susceptible to oxidation and moisture absorption, which can cause porosity in the weld.

You would choose the 4.0mm rod when welding thicker materials where you need to deposit more metal quickly to fill the joint, or when running higher amperages where a thinner rod might melt back too fast.
