Abstract: A method of making cemented carbide powder with low sintering shrinkage including WC and 4-15 wt-% Co and up to 20 wt-% cubic carbide forming elements from the Groups 4 and 5 of the Periodic Table of the Elements by the powder metallurgical techniques wet milling, pressing and sintering. According to the method wet milling is performed in a rotating ball mill with a ratio between the weight of milling bodies and powder of 2-5. The milling bodies are shaped either as spheres or cylinders with semi-spherical end surfaces. The spherical bodies have a diameter of 10 to 15 mm and the cylindrical bodies have a diameter and height of 10 to 15 mm. The composition of the milling bodies is WC with 6 to 10 wt-% Co. A powder made according to the method is described.
