ACCUALA2093T - ERCuAl-A2 Aluminum Bronze TIG Filler Metal 3/32" (10lb)

Tough Rods for Marine and Wear Applications

When you need to weld bronze or repair parts that take a beating from salt water and friction, the Exocor ERCuAl-A2 Aluminum Bronze TIG Rod is your go-to filler. This 3/32" rod is known in the shop as the "workhorse" of copper alloys. It flows smoothly and creates a bead that is both strong and ductile. If you are working on ship propellers, marine valves, or pump housings, this rod gives you the corrosion resistance you need to ensure the repair lasts. It’s also fantastic for building up worn bearing surfaces where metal-on-metal wear is a problem.

One of the best tricks in the book for this rod is its ability to join different metals together. Need to weld a piece of steel to a copper alloy? This is the rod to grab. It handles the mismatch beautifully, giving you a crack-resistant weld. For TIG welding, you'll typically run this with 100% Argon, though some heavy sections might benefit from a helium mix to get that puddle moving. The 36-inch length gives you plenty of feed time before grabbing the next rod, and the 10lb tube keeps your supply clean and straight.

Welders Tips: Cleanliness is key with aluminum bronze. Make sure you remove all oxides, grease, and moisture from the base metal before you strike an arc. While DCEN (Straight Polarity) is standard, using AC current can sometimes help with oxide cleaning on the puddle surface, similar to welding aluminum. Keep your arc length tight and your travel speed steady for the best results.
