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.
