≥2000

With high abrasive resistance,it applies to the semi-finished and finished machining for cast iron non-ferrous metal and its alloys as well as non-metal materials.

 

KG3X

 

YG3X

 

92.5

 

14.9

 

≥1300

It is the fine grain cemented carbide.Among all KG cemented carbides,it has the best wear resistance,but the impact ductility is relatively low.It applies to finished tum or precision bore cast iron.non-ferrous metal and its alloys ,and it is also can be applied to finish machining for steel alloys,hardened steel as well as tuhgsten-moly materials.

 

KG6

 

YG6

 

91

 

14.7

 

≥2700

With high abrasive resistance,it applies to the semi-finished machining and light-load rough machincing for cast iron,non-ferrous metal and its alloys as well as non-metal materials.

 

KG6X

 

YG6X

 

91.8

 

13.3

 

≥1600

It is the fine grain cemented carbide.Its wear resistance is better than KG6,and its toughness is close to KG6.It applies to machine cilled cast iron,alloy cast iron,refractory steel and alloy steel. It is also suitable to finish machine plain cast iron.

 

KG8

 

YG8

 

90

 

13.1

 

≥2700

With a relatively high toughness and good impact resistance,it applies to the semi-finished machining and rough machining for cast iron,non-ferrous metal and its alloys as well as non-metal materials,both continuously and discontinuously.

PT5

 

YT5

 

90.5

 

11.3

 

≥1800

With the best toughness and shock resistance among all the PT alloys,it applies to superficially machine the plian carbon steel and alloy steel including steel forgings and cast parts,as well as to rough turn and rough plane the uneven fracture or when they are machined discontinuously.

 

PT14

 

YT14

 

92

 

 

≥1600

With excellent impact and shock resistance,it is suitable for rough maxhining and semi-finish machining the plain carbon steel and alloy steel.

 

PT15

 

YT15

 

92.5

 

 

≥1300

With excellent wear resistance,it applies to the rough and semi-finished machining for plain carbon steel and alloy steel when they are cut continuously.
