Product details

The mixed powder used in diamond tools is different from the metal powder used in the production of powder metallurgy parts. It not only requires good process performance of the binder and appropriate mechanical properties after sintering, including appropriate hardness, toughness, and strict wear resistance (not the more wear-resistant the better, but also moderate wear resistance), but also has good affinity for diamond. These requirements increase the difficulty of selecting alloy elements.
