The effects of homogenization and brazing conditions on material properties of brazed Al–Mn base alloys were investigated. Low-temperature homogenization enhanced the alloy strength in comparison with high-temperature homogenization. In contrast, high-temperature homogenization induced higher electrical conductivity. Both the strength and electrical conductivity were affected by brazing. The strength increased with a high heating rate, short holding time, and high cooling rate. On the other hand, electrical conductivity increased with a slow cooling rate. Therefore, combining low-temperature homogenization with low cooling-rate brazing should allow maintaining a balance between high strength and good electrical conductivity. The variation of strength after brazing with different homogenization and brazing conditions can be explained by the contribution of solid solution strengthening due to Mn and dispersion strengthening caused by Al–Mn–Si dispersoids.
