China's primary cemented carbide production base is located in Zhuzhou, Hunan. Cemented carbide is widely used in modern tool materials, wear-resistant materials, and materials for high-temperature and corrosive wear environments. The extensive application range of cemented carbide is inseparable from its inherent characteristics.

**Basic Characteristics of Cemented Carbide:**

1.  High hardness and high wear resistance

2.  High elastic modulus

3.  High compressive strength

4.  Good chemical stability (resistant to acids, alkalis, and high-temperature oxidation/corrosion)

5.  Relatively low impact toughness

6.  Low coefficient of thermal expansion; thermal and electrical conductivity similar to iron and its alloys

**Advantages of Cemented Carbide Tools (Compared to Alloy Steel Tools):**

1.  **Dramatically extends tool life by multiples, tens, or even hundreds of times.**  

    *   Cutting tool life can be increased by 5 to 80 times.

    *   Gauge life can be increased by 20 to 150 times.

    *   Die life can be increased by 50 to 100 times.

2.  **Multiplies or increases metal cutting speeds and rock drilling speeds by tens of times.**

3.  **Improves the dimensional accuracy and surface finish of machined parts.**

4.  **Enables the machining of difficult-to-cut materials** (such as heat-resistant alloys, titanium alloys, extra-hard cast iron) **that are challenging for high-speed steel tools.**

5.  **Can be used to manufacture certain wear-resistant parts resistant to corrosion or high temperatures,** thereby enhancing the precision and lifespan of specific machinery and instruments.
