Effect of copper based fillers composition the strength of brazed joint

Vacuum brazing of copper-based filler was performed using pure copper plate as its based metal. The brazed joint were obtained at different temperatures, 680oC and 730oC, with same holding time, which is 30 minutes. MBF 2005 (Cu, 5.7wt.%Ni, 9.7wt.%Sn, 7.0wt.%P), MBF 2002 (Cu, 9.9wt.%Ni, 4.0wt.%Sn, 7...
