G3X (K01) hardness ≥91.5 has the best wear resistance among tungsten-cobalt-titanium-bai alloys, but its impact toughness is poor. It is suitable for high-speed precision of small sections of cast iron, non-ferrous metals and their alloys, broken fire steel, and alloy steel. Processing.

YG3 (K05) hardness ≥90.5, wear resistance second only to YG3X, more sensitive to impact and vibration, suitable for precision turning and semi-finishing turning, threading and reaming during continuous cutting of cast iron, non-ferrous metals and their alloys

YG6A (K10) hardness ≥91.5 is a fine particle alloy with good wear resistance. It is suitable for semi-finishing machining of chilled cast iron, non-ferrous metals and their alloys, and also suitable for semi-finishing machining and finishing of crushed fire steel alloy steel.

YG6 (K15K20) hardness ≥90 has higher abrasion resistance, but lower than YG3, impact and vibration resistance is better than YG3X. It is suitable for semi-finishing and finishing of cast iron, non-ferrous metals and alloys, and non-metal materials with medium cutting speed.

YG8 (K30) hardness ≥89.5 has high strength, impact resistance and shock resistance better than YG6, but the wear resistance and allowable cutting speed are lower. Suitable for low-speed rough machining of cast iron, non-ferrous metals and alloys, and non-metallic materials.
