OVERVIEW

Lincoln SuperGlaze 4043 Aluminum TIG Rod (1/8")

The Lincoln Electric SuperGlaze® 4043 is a premium aluminum-silicon filler metal designed for high-quality Gas Tungsten Arc Welding (GTAW). This 1/8-inch (3.2mm) rod is engineered specifically for welding heat-treatable base alloys, particularly the 6XXX series (such as 6061) and 5052, as well as various weldable cast aluminum alloys. The addition of 5% silicon significantly lowers the melting point of the filler metal relative to the base material, providing excellent fluidity and wetting action. This characteristic makes 4043 the preferred choice for welders seeking a smooth bead profile and reduced crack sensitivity in constrained joints.

Lincoln Electric employs advanced manufacturing processes to ensure the surface of the SuperGlaze rod is exceptionally clean, reducing the risk of porosity and inclusions in the weld deposit. This attention to surface quality translates to better arc stability and a cleaner finished weld. A critical feature for industrial environments is the alloy identification embossed directly onto each rod end. This permanent marking helps quality control managers and welders verify that the correct filler metal is being used, preventing costly material mix-ups in shops that handle multiple aluminum grades.

Packaged in a durable 10 lb carton, these 36-inch cut lengths are ready for immediate production use. The R4043 classification meets AWS A5.10 standards, ensuring compliance with rigorous code requirements. Whether used for pressure vessels, general fabrication, or architectural aluminum structures, the SuperGlaze 4043 delivers consistent mechanical properties and operator appeal.

FAQ

It is generally recommended for welding 5052, any 6XXX series alloys (like 6061), and weldable castings.

Yes, the alloy grade is embossed on each rod end for easy identification, preventing mix-ups.

These rods are 1/8 inch (3.2 mm) in diameter and 36 inches (914 mm) in length.

4043 contains silicon, which provides better wetting action, fluidity, and reduced crack sensitivity compared to 5356. However, 5356 is stronger and better for color matching if anodizing.

You can, but 4043 will turn a dark gray color after anodizing. If color match is critical, 5356 is usually preferred.

100% Argon is the standard gas for TIG welding aluminum. For thicker sections, an Argon/Helium mix can be used to increase heat input.

4043 is generally not recommended for service temperatures above 150°F (65°C) if sustained loads are involved, but it is excellent for general fabrication.
