Classification

|---|---|
| Other standards | EN ISO 24373: Cu5410 (CuSn12 P) |
Purpose
- MIG tin-bronze wire CuSn12 (Cu5410) for welding pure copper and low-alloy copper materials.
Why it works
The higher tin content (12%, versus the 6% typical of bushing-repair bronze wires) gives a harder, less ductile deposit — built for copper industrial equipment rather than sliding/bearing-type parts.
Fields of application
- Welding pure copper and low-alloy copper materials, tanks and boilers, graphite electrode holders, slag baths, oxygen tubing, and electrical equipment.

Advantages
- Harder deposit than 6%-tin bronze wires — better suited to copper industrial equipment than to friction/bearing parts.
- MIG-wire form suits automated production runs on copper equipment.
Limitations
- Lower ductility than 6%-tin bronze wires — not intended for sliding-wear or bearing-type parts.
- No AWS classification is published by the manufacturer for this reference.
