Patent number: 6692690Abstract: There is now provided a cemented carbide grade for rock excavation purposes with 88-96 weight % WC, preferably 91-95% weight % WC, with a binder phase consisting of only cobalt or cobalt and nickel, with a maximum of 25% of the binder being Ni, possibly with small additions of rare earth metals, such as Ce and Y, up to a maximum of 2% of the total cemented carbide. The WC grains are rounded because of the process of coating the WC with cobalt, and not recrystallized or showing grain growth or very sharp cornered grains like conventionally milled WC, thus giving the bodies surprisingly high thermal conductivity. The average grain size should be from 8-30 &mgr;m, preferably from 12-20 &mgr;m. The maximum grain size does not exceed 2 times the average value and no more than 2% of the grains found in the structure are less than half of the average grain size.Type: GrantFiled: April 2, 2002Date of Patent: February 17, 2004Assignee: Sandvik ABInventors: Jan Åkerman, Thomas Ericson
