At General Carbide, we have one of the broadest ranges of tungsten carbide grades in the industry and the tightest specs you'll find anywhere. This lets us produce high-quality grades matched to your most exacting requirements.

Our tungsten carbide grades use cobalt binders ranging in concentrations from 3% to 30% and offer nominal particle sizes from 0.55 microns to 10 microns. In addition, we offer a broad range of tungsten carbide grades with tantalum carbide. Please link to our grade spec sheets at http://www.generalcarbide.com/grade to view the list of our standard grades.

Greenleaf offers a comprehensive line of carbide inserts. An industry pioneer in coated carbide, Greenleaf offers a wide variety of CVD-coated and PVD-coated grades. Greenleaf offers 25 carbide grades ranging from top-performing, sub-micron carbides for heat-resistant aerospace alloys to high-speed turning and milling grades for irons, stainless and alloy steels. Chip control geometries are available for heavy roughing through finishing in a wide array of ANSI/ISO standard insert styles.

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.

Special Materials (Available upon request)

• Cobalt based alloys
• Hastelloy
• Nickel Carbides
• Stellite®
• Various Stainless Steels
