Tungsten Carbide | High Precision Balls

Balls: Tungsten Carbide
Material	Size Range	Grade
Tungsten Carbide	3/32 - 2 1/2” (.0937mm - 63.5mm)	5 - 200

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.
