YG4C

14.9-15.2

1700

89.5

Are coarse grain tungsten carbide alloy, wear resistance and considerable YG3, the use of intensity in the near YG8

For the coal mining industry, setting the system and the pneumatic drill electric drill

YG6

14.6-15.0

1550

90.0

Higher wear resistance, but lower than YG3, YG3X, toughness is higher than YG3, YG3X, can be used more for high speed YG8

For cast iron, non-ferrous metals and their alloys and non-metallic materials when cutting rough frontier car, stopped cutting of semi-refined and refined car car. Can also be used for wire drawing die, geological exploration, coal mining and the limelight with an electric drill

YG8

14.6-14.9

1850

89.0

The use of higher strength, impact and vibration-resistant than YG6 good, but lower resistance to abrasion

For cast iron, non-ferrous metals and their alloys intermittent rough cutting, bar and tube drawing touch; also used an electric drill, oil wells and geological exploration of the drill bit, containing coal feeder teeth; also used in machines and tools easy wear parts, nozzles, top, top rod forging and piercing tools ..

YG8C

14.6-14.9

2100

87.5

Are coarse grain tungsten carbide alloy, the use of performance and wear resistance with similar YG11C

For rotary rock drill bits for medium soft and medium hard rock;and for coal cutting of stone containing formations.

YG11C

14.2-14.5

2400

86.5

Are coarse grain tungsten carbide alloy, the use of strength is slightly higher than YG15, wear resistance is superior to YG15

For tipping of bits for heavy rock drills and rotary hammer rock drills cutting hard rocks.

YG15

13.9-14.2

250

87.0

Strength and toughness against the use of higher wear resistance than the above low-alloy

High intension,lower wear-resistance,suitable for making bits used in rotary machine and heavy rotary machine to drill hard and very hard rock formation.

YG15C

13.9-14.2

2500

86.0

For making drill cone to drill all kinds of formation.
