110011636C - Nexalloy 1100 Aluminum TIG Rod 1.6mm (1/16") - 10lb Tube

Premium High-Purity Aluminum TIG Filler Metal

The Nexalloy 1100 Aluminum TIG Rod is a premium-grade filler metal designed for applications requiring high purity and exceptional corrosion resistance. Composed of 99.0% minimum aluminum, this rod is classified under AWS A5.10 as ER1100. It is specifically engineered for welding base metals of similar composition, such as 1100, 3003, and Alclad 3003. Because it is a commercially pure aluminum alloy, it exhibits a relatively low tensile strength compared to 4000 or 5000 series alloys, making it unsuitable for high-stress structural applications. However, its ductility and softness are unmatched, allowing for excellent formability in the finished weld.

One of the standout characteristics of the Nexalloy 1100 is its superior response to post-weld finishing processes. It is widely regarded as the best choice for applications that will undergo anodizing, as the weld deposit maintains a color very similar to the base metal—typically turning a clear or slight gold tone—unlike 4043 alloys which can turn dark gray or black. This makes it a favorite in architectural and decorative industries.

In addition to its aesthetic qualities, this 1.6mm (1/16") diameter rod offers outstanding thermal and electrical conductivity. This makes it the filler of choice for welding electrical bus bars and other components in the power transmission sector. The 10lb tube packaging ensures a substantial supply for production environments while protecting the rods from atmospheric moisture and contaminants that can lead to hydrogen porosity. Welders can expect a smooth, stable arc and excellent wetting action when using pure Argon or Argon/Helium shielding gas mixtures.

Key Industrial Benefits

For industries dealing with chemical storage and food processing, the high corrosion resistance of the 1100 alloy is critical. It withstands exposure to various atmospheric and chemical agents better than more complex alloys. Whether you are repairing heat exchangers, fabricating food-grade containers, or creating decorative aluminum trim, the Nexalloy 1100 provides the purity and performance required for high-quality TIG welding.
