Main parameters of Cemented Carbide
 2023/04/12

Cemented carbide, also known as tungsten carbide, is a popular material widely used in various industries for its exceptional hardness, wear resistance, and strength. Understanding the main parameters associated with cemented carbide is crucial for selecting the appropriate grade and optimizing its performance in specific applications. In this article, we will explore the main parameters of cemented carbide and their significance in different industrial contexts.


Super Hard Carbide Rod

 

Hardness:

Hardness is a fundamental property of cemented carbide and refers to its resistance to deformation and indentation. The hardness of cemented carbide is typically measured using the Rockwell or Vickers scale. Higher hardness values indicate superior wear resistance and durability, making cemented carbide suitable for cutting tools, wear parts, and abrasive applications.

 

Transverse Rupture Strength (TRS):

Transverse rupture strength measures the ability of cemented carbide to withstand bending forces without breaking. It is an important parameter for tools subjected to high loads and impacts. Higher TRS values indicate greater strength and toughness, enabling cemented carbide to withstand severe cutting or machining operations effectively.

 

Coercive Force (HC):

Coercive force refers to the resistance of cemented carbide to becoming magnetized when exposed to a magnetic field. It is a crucial parameter in applications involving magnetic properties, such as magnetic separators or magnetic tools. Cemented carbide with low coercive force is desirable for efficient magnetic performance and reduced energy losses.

 

Grain Size:

The grain size of cemented carbide refers to the average size of the tungsten carbide particles within the material. Finer grain sizes generally result in improved hardness, wear resistance, and strength. However, a balance must be struck, as excessively fine grain sizes may reduce toughness and impact resistance. The grain size selection depends on the specific application requirements.

 

Cobalt Content:

Cobalt is commonly used as a binder material in cemented carbide, enhancing its toughness and strength. The cobalt content significantly influences the mechanical properties of the material. Higher cobalt content provides better toughness and impact resistance, making it suitable for applications subjected to high shock or vibration. Conversely, lower cobalt content may improve hardness and wear resistance, making it ideal for cutting tools.

 

Surface Finish:

The surface finish of cemented carbide plays a vital role in its performance, especially in cutting and machining applications. A smooth and precise surface finish reduces friction, enhances chip evacuation, and improves tool life. Factors influencing surface finish include the quality of grinding, polishing, and coating processes.

 

Understanding the main parameters of cemented carbide is crucial for selecting the appropriate grade and optimizing its performance in various industrial applications. Hardness, transverse rupture strength, coercive force, grain size, cobalt content, and surface finish are key factors to consider when utilizing cemented carbide. By carefully evaluating these parameters and matching them with specific application requirements, manufacturers can harness the exceptional properties of cemented carbide to achieve superior wear resistance, hardness, and overall performance, contributing to advancements in industries such as cutting tools, wear parts, and magnetic applications.
