◆ Casting Tungsten Carbide(YZF-1)
Binary eutectic tungsten carbide(WC·W2C)．
Carbon content 3.8- 4.1%．
Uneven microstructure(up tu the process adopted)．
Microhardness HV 1700-2200(Load 100g)．
Specific gravity 15.8-16.7g/cm3(theoretic)．
Particle size distribution：20 micron ranged from microns to 4mesh，powder of single or mixed particle size are
available．
Mainly used for oil exploiting drill bit，PCD drill and other melt-penetration products．Also for hard-facting of steel-tooth drill bit，food/vegetable，oil machinery and motor．
