Notes:
This study was carried out to newly develop the fluxes and filler metals for brazingmagnesium alloy AZ31B more easily at lower temperatures. Furthermore, surface preparation wasdeveloped to improve the brazeability of magnesium alloy. The main results obtained are as follows.We could successfully develop the fluxes that consisted of chlorides containing Ca ion and Li ion,which made the faying surface of the magnesium alloy active at around 450℃. In addition, wesucceeded in developing the filler metals with the melting temperatures lower than 490℃ whichwere Mg-Sn-In system containing a small amount of Al to lower the melting temperature. Surfacepreparation for magnesium alloy by immersion in aqueous solution containing halogen ionimproved remarkably the brazeability of the magnesium alloy. Using the surface preparationtogether, the fluxes and filler metals could achieve the brazed joints with a high strength equivalentto that of the base metal
