摘　　要：采用火焰钎焊技术 ,实现了Al/Cu管异种材料的中温钎焊连接。所采用的改进型的CsF -AlF3 钎剂Si粉含量在 1%时 ,钎焊接头的抗裂性能最好。本试验所采用的钎剂具有熔点低、免清洗、无腐蚀、钎剂活性佳和接头抗裂性能好等优点 。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.
