Tungsten Carbide Pen Ball
Description
Tungsten carbide pen ball are develpo in the 1970s, oafter the small batch, always adopt a stainless steel as ball pen situation is broken. Tungsten carbide pen ball use tungsten, titanium, chromium multiple composite carbide solid solution，is the most suitable material for tungsten carbide pen ball.
Features
Include high hardness, high T.R.S., high corrosion and lowest price properties.
Specifications
Tungsten carbide pen ball general sizes is smaller than Ø1mm, the most common sizes are Ø0.28mm，Ø0.35mm，Ø0.48mm and Ø0.5mm, the surface condition of the ball is polished for G25. As the size of tungsten carbide pen ball are too small, it is almost have to customized, the MOQ of the ball is 10 kgs.
