Purpose
- 90/10 cupronickel solid TIG rod (CuNi10) for joining copper-nickel alloys.
Why it works
The 10% nickel content matches the standard 90/10 cupronickel used in seawater piping and condensers — the filler reproduces that same alloy to keep property continuity across the joint.
Fields of application
- Joining 90/10 copper-nickel alloys.

Advantages
- 90/10 alloy — directly compatible with cupronickel piping and condensers of that ratio.
Limitations
- Not suitable for oxy-fuel gas welding.
- Modest mechanical strength (Rm 300 MPa), typical of this family — not intended for high-load structural use.
