      • K10

        Composition: Uncoated, highly wear-resistant fine-grain carbide with enhanced hot hardness properties.
        Application: Best suited for dry and external flood coolant applications in aerospace materials like high-temperature resistant materials and wrought aluminum alloys. Due to its high wear-resistance, this grade is also applicable for cast iron machining at low to medium speeds.
