In which fields are microhardness testers used?

Microhardness testers have a wide range of applications in fields such as the development, research, practical testing, and quality control of metal materials. Especially in hardness testing for special fields, such as Vickers hardness and Knoop hardness, the microhardness tester is used as an alternative performance measure for other material properties. Therefore, the microhardness tester has become one of the important instruments for testing the performance of metal materials in the machinery and metallurgy industries, and is commonly used across various industries.
