HYW Products' ERCuAl-A2 Aluminum Bronze TIG welding rod is a copper-aluminum filler metal (AWS A5.7/A5.7M ERCuAl-A2) supplied in 36" cut lengths for GTAW (TIG). Known for high strength, hardness, and outstanding resistance to wear, cavitation, and salt-water corrosion, it is a go-to choice for surfacing bearing surfaces and for joining and repairing aluminum-bronze castings.
Key Features
- AWS A5.7/A5.7M ERCuAl-A2 copper-aluminum (aluminum bronze) classification
- High tensile strength and hardness for wear- and load-bearing surfaces
- Excellent resistance to corrosion, cavitation, and erosion in seawater
- Well suited to dissimilar-metal joints and anti-galling overlays
- Runs on 100% argon shielding, DCEN (straight polarity) for TIG
- 36" precision-cut rods available in multiple diameters and pack sizes
Ideal Applications
- Surfacing bearing surfaces, gears, bushings, and wear plates
- Repair and joining of aluminum-bronze castings and propellers
- Marine hardware, pump and valve components, and shafts
- Corrosion- and cavitation-resistant overlays
- Joining dissimilar metals and build-up of worn parts
