SANDVIK H6F extra-fine grain cemented carbide grades has been developed to meet the exacting demands placed on solid carbide tooling by modern technology. SANDVIK extra-fine grain cemented carbide grades are true sub micron grain size tungsten carbide alloys. The tungsten carbide grain size is 0.8 µm, which is precisely controlled. These grades offer an excellent combination of strength and toughness. In addition, a special additive maximizes corrosion resistance without loss of toughness. SANDVIK grade H6F incorporates 6% cobalt (Co) and 94% tungsten carbide (WC). SANDVIK grade H6F is recommended for solid carbide rotary tool applications in the ISO K05/K10 range with special advantages where exceptionally sharp edge profiles are demanded.
