Grade	Average WC Grain Size (µm)	Binder Content (wt. %)	Hardness (HRA)	Density (g/cm3)	TRS (1000 psi)	Typical App.
90	2 –4	10.0 Co	89.1	14.50	470	Grades having the highest levels of toughness and thermal cracking resistance for a given level of abrasion resistance. Specifically designed for use as cutting elements of rotary-cone bits employed for oil and gas exploration and mining. In general, abrasion resistance increases with lower binder content and higher hardness, while toughness and thermal cracking resistance increases with higher binder content.
