Cu 10Sn based diamond saw blades for cutting cured concrete were studied by the orthogonal table design. The effect of iron, nickel, WC contents,diamond size,additive A,additive B(rare earth) and sintering parameters (temperature,holding time) on the TRS of diamond segments and cutting performance of diamond saw blades were analyzed.The results showed that Fe and Ni contents and keeping time were the key factors which influenced the retention of diamond in the bond while the sintering temperature,Fe content and diamond size were the key factors which influence the tool life. The appearance of used saw blades were observed by SEM.
