Traditional Grades of Tungsten Carbide
Wear resistance and cutting speed higher than YT15 but strength and impact toughness comparatively lower. Finishing of carbon steel and alloy steel, for instance fine turning, fine boring or fine reaming of their small chip sections
Wear resistance higher than YT5,but impact toughness lower than YT5.Semifinishing of the medium chip sections of steel, cast steel and alloy steel or finishing of their small chip sections.
High strength in use and good impact & shock resistance, yet lower than YT5,Rough turning and rough milling of carbon steel and alloy steel during continuous cutting or medium to fine turning of them during intermittent cutting.
Best strength and height impact & shock resistance among W-Co-Ti alloys but wear resistance comparatively lower. Rough turning, rough planning and half precision planning of carbon steel and alloy steel (including forged steel parts, stamped parts and cast iron surfaces).
High red hardness, resistant to impact load. A goo grade for general purposes Machining of ordinary steel, cast irons and hard to machining materials such as refractory steel manageress steel, and stainless steel.¡¡
High red hardness and high strength in use, resisting high impact load, A good grade for general purposes, Machining and medium machine of cast irons and problem materials such as refractory steel, manganese steel, stainless steel and advanced alloy steel.
Wear resistance second to YW1 yet strength comparatively higher and resistant to high impact load. Roughing and medium machining of ordinary steel cst irons as well as refractory steel, manganese steel, stainless steel and advanced alloy steel.
Best wear resistance among W-Co alloys yet impact toughness comparatively low, High speed finishing of small chip section of cast irons, non-ferrous metals & alloys quenched steel and alloy steel.
Wear resistance less than YG3X only, sensitive to impact and vibration for continuous semi-finish and finish turning of castiron, non-ferrous metals and their alloys and for finish turning of threads and reaming.
Fine-grained alloy, good; wear resistance. Semi-finishing of chilled cast iron, non-ferrous metals/alloys; semi-finishing and finishing of hardened steel, alloy steel.
