Cemented Carbide Core and Valve:
any specifications,shapes and dimensions can be supplied as per specific requirements of the customers by drawing and samples
According to customer blueprint, may produce the ring of finished product and the blank ring of hard alloy of different brand
Materials: hard alloy and nonmetal as DIN.Used in geological prospecting, machinery/tool manufacturing and serves as drill bit in wind drill and electric drills for coal diggingFit for precision lathe are used in nonstop cutting of die-cast ironSemi-precision, precision, and small-section precision lathes are used in interrupted cutting and whirling of rough turnC/O available;Tungsten Carbide are not only widely applied in the oil industry, but also used as pivots or detents for gauges, tips for ballpens, button for tracers, ball grinder, bearing, valve ball etc.
