摘要

LD30 aluminum alloy with 304 stainless steel using low temperature brazing was performed in the wettability research. Through wettability study contrast, three kinds of low melting point solders 60Sn-40Pb, Sn-3.5Ag and 35Sn-40Pb-25Bi which were suitable for LD30 aluminum alloy and 304 stainless steel were chosen, and solder flux was selected. The joint of microstructure, phase composition, X-ray inspection were analyzed. Results show that the 60Sn-40Pb and 35Sn-40Pb-25Bi combine with H₃PO₄ have good wettability on 304 stainless steel; the 60Sn-40Pb and 35Sn-40Pb-25Bi combine with 50% H₃PO₄ and 50% glycol have good wettability in the brazing experiment and the Sn-3.5Ag has relatively poor wettability.
