Purpose
- Aluminum bronze covered electrode (ALBRONZE) for repairing all grades of aluminum bronze and surfacing cast iron, steel and copper subject to corrosion, cavitation, erosion and metal-to-metal wear.
Why it works
Aluminum bronze combines mechanical strength with a self-protecting aluminum-oxide layer — hence its specific use on parts exposed to seawater and marine environments, where galvanic corrosion would be a problem with other fillers.
Fields of application
- Repairing aluminum bronzes of any grade.
- Surfacing cast iron, steel and copper exposed to corrosion, cavitation and erosion.
- Parts in marine and seawater service.

Advantages
- Self-protecting oxide layer — good performance in marine environments.
- Resists corrosion, cavitation, erosion and metal-to-metal wear.
- Covered electrode — no shielding gas needed.
Limitations
- No detailed chemistry/mechanical data in the supplier datasheet — see also the MIG variant (FERVEO CUP AL8 MIG) for mechanical values.
