Brazing Flux
Huazhong brazing flux series is available in powder, paste and liquid forms, which are essential auxiliary materials for brazing processes. The flux effectively removes oxide films on base metals and prevents re-oxidation, significantly improving wetting and spreading performance of molten filler metal. It ensures uniform, neat weld formation and forms consistent, reliable brazed joints.
Product Series | Product Number | Related Standard | Product Name | Characteristic | Application |
| Brazing Flux | D4 | EN1044-FH12 | Silver Brazing Powder | It does not absorb moisture and will never clump; it is highly active and can effectively remove oxides from various metal surfaces, promoting solder flow; it has a low activation temperature and a wide range of applications. | With a melting point of approximately 550℃, it is used as a flux for brazing copper and copper alloys, steel and stainless steel in the range of 600-850℃ when combined with silver brazing filler metal. |
