— Diameter Range:0.6mm--70mm, and Undertake order of
non-standard size work.
— The product tolerance can be reached as less than
0.001mm, and the grinding accuracy is between G5-G1000.
The Advantages for Tungsten carbide pen balls:
— Eco: Smooth writing & no leakage.
— Apply to advertising pen,promotion pen, ball pen, metal pen, office pen, commemorative pen etc.
— Using 100% virgin fine grain tungsten powder;

1, High hardness, crushing force with superior force and mixing;
2, With excellent wear resistance,the service life is dozens of
times longer than steel ball;
3,High temperature resistant, at high temperatures of 1000 degrees
can still maintain high hardness and other mechanical
properties;
4, Corrosion resistance, resistance to corrosion of acid alkaline
substances;
Application of carbide balls
Application for ball pen, ball-bearing, sealing valve, high
precision instruments, hardness test machine, head pressure, mine,
decorations and other special precision industry.
