SANDVIK H6FF extra-fine grain cemented carbide grades has been developed to meet the exacting demands placed on solid carbide tooling by modern technology. The range of SANDVIK extra-fine grain cemented carbide grades have a tungsten carbide (WC) grain size of 0.6 µm. This grain size is precisely controlled to produce a tool material with an excellent combination of strength and toughness. In addition, a special additive maximizes corrosion resistance without loss of toughness. SANDVIK grade H6FF has been developed as a result of an extensive research program aimed at optimizing wear resistance, toughness and strength. SANDVIK grade H6FF incorporates 6% cobalt (Co) and 94% tungsten carbide (WC). SANDVIK grade H6FF is recommended for solid carbide rotary tool applications in the ISO K05/K10 range. It has special advantages where high toughness, sharp edge profiles and exceptional wear resistance is required. Information provided by Sandvik |
