Purpose
- High-alloy aluminum-nickel bronze solid TIG rod (CuAl9Ni5Fe3Mn2), excellent corrosion resistance — seawater-resistant surfacing.
Why it works
The higher nickel content (4.5%) versus CUP AL8NI2 MIG (2.2%) gives the best corrosion resistance in this datasheet's aluminum bronze family, along with the highest mechanical strength (Rm 650 MPa, hardness 180 HB) — the supplier explicitly highlights it for seawater-resistant surfacing.
Fields of application
- Joining copper-aluminum-nickel alloys.
- Seawater-resistant surfacing on unalloyed and low-alloy steels, and cast steel parts.

Advantages
- Excellent corrosion resistance — the highest nickel content in the CUP AL family.
- The highest mechanical strength in the family (Rm 650 MPa, 180 HB).
- Explicitly recommended for seawater service.
Limitations
- Not suitable for oxy-fuel gas welding.
- Reduced ductility (A5 10%) due to the high strength.
