Tungsten Carbide Ball for Pen Surface Condition

Tungsten carbide ball has high hardness, wear resistance, corrosion resistance, can replace all the steel ball products in harsh environment. Tungsten carbide ball for pen is often used in producing ballpoint pen. Furthermore its surface condition has an important impact on the writing performance.

Describe the surface condition of the tungsten carbide ball for pen has two aspects, one is the surface roughness, and second, the ball surface and pore size distribution. Any type of tungsten carbide ball for pens to achieve good writing requirements, must have a low surface roughness and tungsten carbide inserts uniform fine pores. And throughout the writing process, tungsten carbide ball for pen is relatively stable characteristics can be maintained for a long time, and change little. When such writing can effectively reduce wear between the ball and the ball seat, capillary action through the porous ink is slowly taken out continuously while the excess ink back to the ball seat body, to ensure the stability and excellent writing property.
