Cu-Fe composite matrix of diamond grinders are investigated through sintering alloy powders by means of vacuum impressed sintering.Consequently,microscope,XRD and hardness test are used to investigating relationships between the metallurgical microstructure characteristics and mechanical properties.The results show that elements alloying,metallurgical bonding completely takes place under the sintering temperature of 930℃,and the metallurgical bonding rate will raise with the increase of sintering temperature.When the sintering temperature is above 930℃,fine combination occurs without diamond carbonization,and the sintered composite matrix obtains a hardness of 160HB.
