The brazed joint was obtained at different temperatures, 680<sup>o</sup>C and 730<sup>o</sup>C, 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, 7.8wt.%P) and VZ 2250 (Cu, 7.0wt.%Ni, 9.3wt.%Sn, 6.3wt.%P) alloys were used as brazing filler materials. The intermetallic compound (IMC) and mechanical properties of the joints were investigated in detail. The result show that the interfacial microstructure of the brazed joints is Cu<sub>3</sub>P and (CuNi)<sub>2</sub>P. As the brazing temperature increase from 680<sup>o</sup>C to 730<sup>o</sup>C, the IMC become thicker leading to decrease in joining strength due to brittle IMC formation. The maximum shear strength reached 112 MPa at 680<sup>o</sup>C for MBF 2002 and 129 MPa at 730<sup>o</sup>C for MBF 2005. Hence, it is found that the composition of filler effects the strength of brazed joint.</p>}, number={2}, journal={Journal of Mechanical Engineering and Sciences}, author={Sulaiman H., A. J. and W.
