Grades	Density(g/cm³)	Hardness (HRA)	T·R·S (N/mm2)	Application
YG4C	15.00	89.5	1800	Mainly used as small s for percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations.
YG6	14.80	90.0	1700	Mainly used as the s of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations.
YG8	14.70	88.5	2200	Mainly used as the s of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations.
YG8C	14.70	88.0	2300	Mainly used as the s of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations.
YG9C	14.60	87.0	2400	Mainly used as the inserts and s for rotary-percussive bits, coal-cutting bits and tri-cone bits to cut medium-hard and hard formations.
YG11C	14.40	86.5	2450	Mainly for the inserts and s of heavy rock drill bits and rotary-percussive bits, coal-cutting bits and tri-cone bits to cut medium-hard and hard formations.
YG13C	14.30	86.0	2500	Mainly used as the inserts and s of tri-cone bits rotary-percussive bits and heavy rock drill bits to cut medium-hard and hard formations.
YG15	14.20	86.5	2500	It is stronger, and is mainly used as the inserts and s of rotary-percussive bits, heavy rock drill bits to cut hard and very hard formations.
YG16	14.10	85.5	2600	It is mainly used for making cemented carbide substrate tips to be used in PDC cutters for excavating coal and oil field PDC bits.
YG20	13.70	85.0	2800	Mainly for the stamping dies used in the conditions of heavy impact load and large stress.
