Classification
| AWS class | ER Cu |
|---|---|
| EN ISO class | ~S Cu 1898 (CuSn1) |
Purpose
- Pure copper solid wire (with deoxidizers) for joining pure copper alloys — porosity-free deposits.
Why it works
Deoxidizers in the alloy scavenge dissolved oxygen from the weld pool, preventing the porosity typical of copper welding — hence the supplier's note that it produces sound, porosity-free welds.
Fields of application
- Joining pure copper parts (DIN 2.0040, 2.0070, 2.0076, 2.0090, 2.1293 and equivalents).

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.

Advantages
- Deoxidizers in the filler — porosity-free deposits.
- Also suitable for oxy-fuel gas welding.
Limitations
- Modest mechanical properties (Rm 220 MPa, hardness 50 HB) — typical of pure copper, not intended for high-strength structural use.
