Tungsten Carbide Needles Facts

Tungsten carbide needles, has extraordinary high hardness than needles of other materials. It is more often used in industries to penetrate into many other hard materials. Tungsten carbide needles are often of fine finished surface, and the tip of it is tapered and flat. There are different tungsten carbide needles of varied diameters, which are put to use for different purpose. For its harness, tungsten carbide needles can resist wear resistance and abrasion.

Tungsten Carbide Seals in Mechanical Use

Tungsten carbide seals perform better than many other mechanical seals. It is used to prevent fluid from leaking out or used to control the leakage path between two surface. Sintering from tungsten carbide, tungsten carbide seals have high density and hardness, and the most important is that, tungsten carbide seals can resist abrasion and corrosion, which are the most significant factors of mechanical seals. For these properties, tungsten carbide seals become more and more popular in mechanical sealing areas.

Tungsten Carbide Rod Extrusion Process

Tungsten carbide rods can be manufactured from the process of pressure and extrusion. Before the extrusion process, tungsten carbide powder is firstly mixed with certain quantities of cobalt powder or nickel powder as its binders. And then the mixed powder is put into the extrusion machine. Under the certain pressure, and with the removal of the air, tungsten carbide powder is extruded into tungsten carbide rods through the orifice of specific diameters.

Process of Tungsten Carbide Polish Ball

Tungsten carbide polish ball is manufactured on the basis of tungsten carbide blank ball. After pre-sintered, tungsten carbide blank ball is in rough and ground surface, so it has to remove all the imperfections on the surface. After this procedure, you should further polished the blank balls to achieve a bright surface condition. For the brightness of the surface, tungsten carbide polished balls are usually applied to many work fields where precision characteristics are strictly required.
