Classification
| AWS class | ER CuSn-A |
|---|---|
| EN ISO class | S Cu 5180P (CuSn6P) |
Purpose
- Tin bronze solid wire (CuSn6P) for joining copper-tin alloys, brass, and surfacing on cast iron.
Why it works
Phosphorus (0.2%) acts as the bronze's own deoxidizer, giving a clean deposit; the CuSn6P alloy matches the standard bronze used in bearings and friction gears.
Fields of application
- Joining copper-tin alloys, brass, cast copper-tin-zinc-lead alloys.
- Surfacing on cast iron.

Advantages
- Phosphorus as a built-in deoxidizer — clean deposit.
- Also suitable for oxy-fuel gas welding.
Limitations
- Moderate hardness (90 HB) — for moderate-friction parts, not severe abrasive wear.
