Tungsten Carbide Balls & Special Materials Download Product Sheet

Tungsten Carbide balls are manufactured in two standard material grades of C-1 and C-2.  Nickel and other special grades are quoted upon request.

C-1, with better shock resistance than C-2, this grade is typically used as a mining grade where toughness and abrasion resistance are also important.  It has also proven useful in bearing applications.

C-2 affords higher wear resistance and toughness which make this grade an excellent general purpose grade for use in pumps and valves.
