OVERVIEW

High-Performance Aluminum TIG Welding Rods

The Nexalloy 4943 Aluminum TIG Rod is a premium filler metal designed to provide superior strength and weldability for aluminum fabrication. Packaged in a convenient 10lb tube, these 36-inch cut lengths are perfect for professional welders and fabrication shops looking to upgrade their aluminum welding results. The 3/32" (2.5mm) diameter is a versatile size, suitable for a wide range of material thicknesses commonly found in automotive, marine, and general repair applications.

Nexalloy is known for producing consistent, high-quality aluminum filler metals. This ER4943 alloy was developed to bridge the gap between the ease of use of 4043 and the strength of 5356. It offers excellent bead appearance and flows smoothly, making it a favorite among TIG welders who demand precision. Whether you are repairing a cast aluminum part or fabricating a custom structural frame, this rod ensures a reliable and strong bond.

At Josef Gas, we understand the importance of having the right filler metal for the job. The 4943 alloy is particularly beneficial because it does not suffer from the dilution issues that can affect 5356, yet it provides higher strength than the standard 4043. This makes it an excellent "go-to" rod for 6xxx series aluminum projects. Stock up on this essential consumable to ensure your shop is ready for high-quality aluminum work.

Key Benefits

  • Enhanced Strength: Provides higher yield and tensile strength than standard ER4043.
  • User Friendly: Maintains the excellent fluidity and low crack sensitivity welders love in 4043.
  • Versatile: Suitable for a broad range of aluminum grades, especially 6061.

FAQ

ER4943 offers significantly higher tensile and yield strength than ER4043 while maintaining similar fluidity and low crack sensitivity.

Yes, ER4943 is an excellent choice for welding 6061 aluminum and often provides better joint strength than 4043.

No special gas is required; it uses standard 100% Argon or Argon/Helium mixtures commonly used for TIG welding aluminum.

Yes, ER4943 is a heat-treatable alloy, making it suitable for applications where post-weld heat treatment is required.

Like most aluminum TIG welding, this rod should be used with Alternating Current (AC).

This product comes in a 10lb tube containing 36-inch cut lengths.

In many structural applications for 6xxx series aluminum, yes. It avoids the temperature-service limitations of 5356 and offers better flow, though 5356 is still preferred for 5xxx series base metals.
