Nano, ultrafine, and submicron grades
Cemented carbide grades with binder content in the range of 3 to 10 wt% and grain sizes below 1 μm have the highest hardness and compressive strengths, combined with exceptionally high wear resistance and high reliability against breakage. These grades are used in a wide range of wear parts applications and in cutting tools and carbide drill bits designed for metallic and nonmetallic machining for which a combination of high strength, high wear resistance, and sharp cutting edges are essential.
