| COPPER BASED BRAZING ALLOYS (BRASS) |
 |
 |
|
 |
Our copper based brazing alloys offer a range of self fluxing alloys for brazing copper in
air. We have developed copper based brazing alloys, which can be used in refrigeration,
plant and equipment, water heaters, calorifiers, electric elements, motors and
transformers. However, we also offer customised solutions as per the clients'
application and specifications. |
