How to Choose
The main difference between WC-5Co, WC-6Co, WC-8Co, WC-10Co, WC-12Co, WC-15Co, and WC-17Co tungsten carbide (WC) alloy powders lies in the varying cobalt content, which directly affects the properties of the material. Here are the characteristics and key differences of each alloy powder:
-
WC-5Co (5% cobalt):
- Highest hardness, excellent wear resistance
- Lower toughness, suitable for environments with extreme wear, such as cutting tools and molds
-
WC-6Co (6% cobalt):
- Slightly lower hardness than WC-5Co, but slightly improved toughness
- Commonly used in cutting tools and wear-resistant parts, offering a good balance of hardness and toughness
-
WC-8Co (8% cobalt):
- Balanced hardness and toughness, good wear resistance, and moderate impact resistance
- Suitable for applications requiring higher toughness, such as impact tools
-
WC-10Co (10% cobalt):
- Significant improvement in toughness, better impact resistance
- More suitable for environments with impact and vibration, such as mining tools and drills
-
WC-12Co (12% cobalt):
- Further increased toughness, with slightly reduced hardness
- Ideal for high-impact and high-vibration applications, such as drilling tools and heavy-duty cutting
-
WC-15Co (15% cobalt):
- Even better toughness, though hardness and wear resistance are relatively lower
- Used in applications requiring high-impact resistance and strength, such as mining machinery and construction equipment parts
-
WC-17Co (17% cobalt):
- Maximum toughness, excellent impact resistance
- Suitable for extreme impact loads and harsh environments, often used in mining and oil and gas industries
Summary:
- Lower cobalt content (e.g., WC-5Co, WC-6Co) results in higher hardness and wear resistance, but lower toughness, making these alloys ideal for applications that require high hardness and wear resistance.
- Higher cobalt content (e.g., WC-10Co, WC-12Co, WC-15Co, WC-17Co) provides better toughness and impact resistance, making these alloys more suitable for applications that require resistance to impact and vibration.
Choosing the right cobalt content based on the specific application can optimize the performance and lifespan of tools or components.
