INTERNATIONAL CLASSIFICATIONS |
AWS/ASME A 5.6 E CuSn – C
DIN 1733: EL - CuSn7
FEATURES & APPLICATIONS |
Repairing bronze parts, especially those that are subject to sea water and many other chemicals.
- A special tin-bronze electrode for joining and surfacing on DC (+).
- Tin content makes deposits harder and more wear resistant.
- Deposits are uniform and porosity free.
- Slag is easy to remove.
- Also available in TIG form as item #6008.
