Tube rod is composited by Cemented Carbide Pellet, Spherical CTC and CTC. The layer has higher impact resistance, better wear resistance and good fluidity than other rods. Wear resistance is 6-7 times better than others. Tested by ASTM B611 method. Widely used in surfacing welding of oil drilling tools, PDC drilling, construction machinery, screw propeller (auger) blades, exhaust fan impellers, mixer blades, mud pumps, coal mine chutes, etc., crusher blades, mining machinery, coal mine drill pipes, sugar cane extraction Knives, sand mixers, etc.
