Creating a comprehensive comparison table for commonly used cemented carbide grades across various countries involves considering different standards and designations. Below is a simplified
overview of some widely used grades, focusing on their composition and applications:
Comparison Table

| Grade Designation | Composition |Applications | Country/Region |
|-----------------------|-----------------|-------------------|-------------------|
| YG6 (6% Co) | WC + 6% Co | Cutting tools, wear parts | China, General Use |
| C2 (6% Co) | WC + 6% Co | Metal cutting, energy | USA, General Use |
| K20 (6% Co) | WC + 6% Co | Metal cutting, energy | ISO Standard |
| C3 (3% Co) | WC + 3% Co | High wear resistance, no shock | USA, Specialized Use |
| K10 (3% Co) | WC + 3% Co | High wear resistance, no shock | ISO Standard |
| YT15 (15% TiC) | WC + TiC + Co | High-speed cutting tools | China, Specialized Use |
|C12 (15% Co) | WC + 15% Co | Wear & die applications, defense | USA, Specialized Use |
| K40 (12-15% Co) | WC + 12-15% Co | Metal cutting, wear & die | ISO Standard |
Key Points
- YG6: Commonly used in China for cutting tools and wear parts, with 6% cobalt content.
- C2: Used in the USA for metal cutting and energy applications, also with 6% cobalt.
- K20: An ISO standard grade similar to YG6 and C2, used globally.
- C3: Known for high wear resistance without shock, used in specialized applications.
- K10: Similar to C3, used for high wear resistance.
- YT15: Includes titanium carbide for high-speed cutting tools.
- C12: Used in wear and die applications, often in defense.
- K40: Offers a balance of toughness and wear resistance.
