  • + -What is Cemented Carbide
    Cemented carbide, also known as tungsten carbide (WC)-based composite, is a hard and wear-resistant material used in cutting tools, mining tools, and wear-resistant parts. It consists of hard carbide particles (usually WC) bonded together by a metallic binder.
  • + -What is the Component in the Cemented Carbide

    Composition of Cemented Carbide

    Component

    Function

    Typical Percentage (%)

    Tungsten Carbide (WC)

    Provides hardness & wear resistance

    70-95%

    Binder Metal (Co, Ni, Fe)

    Gives toughness & ductility

    5-30%

    Other Carbides (TiC, TaC, NbC, etc.)

    0-10%

  • + -Common Binder Metals

    Binder Metal

    Properties

    Applications

    Cobalt (Co)

    Best toughness, good wear resistance

    Most cutting tools, general-purpose carbide

    Nickel (Ni)

    Better corrosion resistance than Co, slightly lower toughness

    Medical tools, chemical-resistant applications

    Iron (Fe)

    Cheaper alternative, lower performance than Co/Ni

    Wear parts, industrial components

  • + -Understanding Carbide Grades
    Carbide grades are classified based on their composition, application, and performance in cutting and machining tasks. These grades determine the hardness, toughness, and wear resistance of carbide tools.

    🔹 1️⃣ P-Grades (Blue): For Steel & Alloy Steels
    P01 - P20: High-speed machining and finishing. Best for light cuts with high surface quality.
    P30 - P50: Medium to roughing operations, suitable for interrupted cuts.
    Applications: General steel, carbon steel, low-alloy steel.

    🔹 2️⃣ M-Grades (Yellow): For Stainless Steel & Cast Iron
    M10 - M20: Great for machining stainless steel, cast iron, and non-ferrous metals. Offers a good balance of toughness and wear resistance.
    M30 - M40: Suitable for more aggressive cuts and tougher materials.
    Applications: Stainless steel valves, cast iron components, medical instruments.

    🔹 3️⃣ K-Grades (Red): For Cast Iron & Non-Ferrous Metals
    K01 - K20: Ideal for high-speed finishing of cast iron and non-ferrous metals.
    K30 - K40: Optimized for roughing operations and interrupted cuts.
    Applications: Brake rotors, engine blocks, aluminum parts.

    🔹 4️⃣ S-Grades (Green): For Super Alloys & Titanium
    S10 - S20: Designed for cutting high-temperature alloys and titanium. Good for maintaining hardness at elevated temperatures.
    S30 - S40: Better for interrupted cuts and harder superalloys.
    Applications: Aerospace components, turbine blades.

    🔹 5️⃣ H-Grades (Grey): For Hardened Steels
    H10 - H20: Best for hardened materials up to 65 HRC.
    H30: Specialized for extremely hard materials and precision finishing.
    Applications: Dies, molds, hardened shafts.
