Abstract：A lower cost superfine copper-cobalt-iron alloy powder was selected to replace the cobalt powder in the
binder of diamond circular saw blade for wet cutting of high hard tile, and the influence on the performance of the
saw blade was studied. The results showed that there was a certain decrease of the cutting speed of the product
after substitution, but when the price of cobalt powder was higher than 400 yuan/kg, the cost performance of the
product was significantly improved. the higher the substitution ratio, the more obvious the cost performance advantage.
The superfine CuCoFe alloy powder is more suitable for general diamond tools when the price of cobalt powder
is high. Cobalt powder has advantages in performance and is more suitable for professional diamond tools.
