WebJun 17, 2024 · The DSC results of the BNi-7 brazing alloy alloyed with varied Cu content are shown in Table 1. The liquidus temperature of the brazing alloys decreases with the increased Cu content. The liquidus temperature of BNi-7 + 9 wt.% Cu brazing alloy is 871.8 °C, which is lower than that of traditional BNi-7 (890.1 °C). The results verify our prediction.
