FLAME BRAZING FOR DISSIMILAR MATERIALS OF Al/Cu TUBE |
| |
| Abstract: | The flame brazing technology for joining Al/Cu tube at middle-range temperature is realized. The optimal joint against cracking is produced by means of improved CsF-AlF 3 flux containing silicon powder about 1vol% and the brazing flux has excellent properties of low melting point, non- cleaning, good corrosion resistance and high brazing activity, and the brazed joints have good ductility. It is proved that the developed technology for Al/Cu tube achieves domestic leading level. |
