Which are the most relevant attributes related to cemented carbide?

Introduction: Why Cemented Carbide is a Material of Choice

Cemented carbide, also known as tungsten carbide, is one of the most important engineered materials in modern industry. Its unique combination of hardness, toughness, and wear resistance has made it indispensable for cutting tools, wear parts, and high-performance components.

For industries such as steel and metal processing, machinery and tool manufacturing, electronics, glass processing, and industrial equipment OEMs, understanding the key attributes of cemented carbide is essential for selecting the right components and ensuring long-term reliability.

Wear Resistance: Durability in Harsh Environments

One of the most significant attributes of cemented carbide is its exceptional wear resistance. This property ensures:

• Long service life even under high friction conditions.
• Reduced downtime due to less frequent tool replacement.
• Superior cost efficiency over time compared to traditional steels.

Applications include roll rings, cutting inserts, and wear parts used in steel rolling mills and machining processes.

Toughness: Balancing Strength with Shock Resistance

While hardness is critical, toughness ensures that cemented carbide can withstand mechanical shocks and impact loads without catastrophic failure. Toughness depends on the material’s binder content and grain size.

This property makes cemented carbide suitable for heavy-duty industrial tools that experience sudden changes in force, such as in metal forming and mining applications.

Hardness: The Core Property of Cemented Carbide

Hardness is what distinguishes cemented carbide from many other materials. With values ranging between 1,600–2,200 HV (Vickers Hardness), cemented carbide surpasses most steels. High hardness translates into:

• Exceptional cutting ability for machining hard materials.
• Resistance to abrasion and deformation.
• Dimensional stability during high-precision operations.

Mechanical Strength: Supporting Heavy-Duty Applications

Cemented carbide components offer compressive strengths up to 6,000 MPa, making them ideal for heavy mechanical loads. This strength allows them to be used in:

• Roll rings for steel rolling mills.
• Dies and punches in forming applications.
• High-stress components in industrial machinery.

Density: Implications for Performance and Applications

With a density typically ranging from 13.5 to 15.0 g/cm³, cemented carbide is significantly denser than steel. This property is particularly useful in applications requiring mass, stability, and vibration damping, such as precision machining tools.

Thermal Properties: Heat Resistance and Conductivity

Cemented carbide demonstrates excellent performance under high temperatures:

• Melting point: Above 2,800°C.
• Thermal conductivity: Allows for rapid heat dissipation.
• Thermal stability: Maintains hardness and strength at elevated temperatures.

This makes it invaluable in cutting, grinding, and forming processes, where heat buildup can degrade conventional materials.

Electrical and Magnetic Properties: Specialized Industrial Uses

• Slight electrical conductivity allows applications in electrical discharge machining (EDM).
• Magnetic properties depend on binder composition, useful in specialized industries.

These attributes expand its use in electronics and glass processing equipment.

Corrosion Resistance: Extending Tool and Component Lifespan

• Long-term durability in chemical processing.
• Reliability in humid or corrosive environments.
• Consistent performance in marine and industrial applications.
