There is a certain positive correlation between the strength and hardness of cemented carbide. Generally speaking, the higher the hardness of cemented carbide, the higher its strength. This is because hardness and strength are both parameters that characterize the material’s ability to resist wear and scratches, and materials with high hardness and strength usually have better resistance to wear and scratches.
However, it should be noted that hardness and strength are not completely equivalent concepts, and there is not a simple proportional relationship between them. In some cases, an increase in the hardness of a cemented carbide may result in a decrease in its toughness, and vice versa. Therefore, when selecting cemented carbide, comprehensive considerations need to be made based on the actual application scenario to obtain the best combination of strength and hardness.
In addition, the specific measurement methods for hardness and strength are different, so the measured results may vary under different circumstances. Therefore, specific testing and analysis of hardness and strength are required in specific applications to determine the most suitable materials and performance requirements.
To sum up, there is a certain positive correlation between the strength and hardness of cemented carbide, but it is not a simple proportional relationship. It is necessary to comprehensively consider the actual application scenario, material type and other factors for selection and application.
