Aluminum Bronze - Tig Rod
ERCuAl-A2 aluminum bronze TIG rod is a copper-aluminum GTAW filler (AWS A5.7) prized for strength, wear resistance, and corrosion resistance. It welds and surfaces aluminum bronze, joins dissimilar metals (copper alloys to steel), and builds up bearing and wear surfaces — common on propellers, pump and valve parts, dies, and bushings. 36" cut lengths under argon.

Frequently Asked Questions
What is ERCuAl-A2 used for?
Welding and repairing aluminum bronze, joining copper alloys to steel, and overlaying wear and bearing surfaces — propellers, pump/valve components, dies, and bushings that need wear and corrosion resistance.
Does aluminum bronze resist corrosion?
Yes — aluminum bronze offers strong resistance to corrosion and cavitation, which is why it's favored for marine and fluid-handling parts.
