Lower (640 ° C or so) and steel friction, its wear resistance is poor.Therefore, can not cut steel, but in the difficult processing of materials or vibration of the special circumstances, because the cutting speed is not high, and the tool
Less cobalt content (such as YG3) its hardness, wear resistance and high heat resistance, suitable for finishing.
Strength and toughness requirements are more prominent, the use of K class alloy more appropriate.
(WC) and cobalt (Co0 composition, bending strength and toughness, is used for processing cast iron, hard bronze and other brittle materials or a great impact on the occasion of such alloys and steel bonding temperature
