Properties

Application

YG3X

?15.0-15.3

92

Having the highest wear-resistance, but the toughness is the worst

For the drawing of cast-iron and fine wire and the wear-resistance is superior.

YG4C

14.9-15.2

90

Belonging the coarse tungsten carbide, the wear-resistance is higher than YG8S.

For geological prospecting, coal mining, tipping of electric and air drill for coal bed.

YA6

14.4-15.0

92

Belonging the fine tungsten carbide, having more advantages than YG6X.

For the semi-fine machining of hard cast-iron {~} ferrous metal and alloy.

YG6

14.6-15.0

89.5

Having higher wear-resistance, but lower than YG3X.

For cast-iron, rough turning of threads, spiral turning and coarse {~} fine boring of holes.

YG6X

14.6-15.0

91

Belonging the fine tungsten carbide, having higher wear-resistance.

For machining cast-iron and thermal-resistance alloy, plain cast-iron, for making timber cutters.

YG8

14.4-14.8

89

Having higher strength and the shock-resistance is better than YG6.
