How should the test force of a Vickers hardness tester be selected?

The test force of the Vickers hardness test can be as small as 10gf, and the indentation is very small, making it particularly suitable for testing thin and small materials. However, the efficiency of the Vickers hardness test is relatively low, with high requirements for experimental techniques and the surface finish of the specimen. Usually, specialized specimen preparation is required, which is cumbersome and time-consuming, so it is typically used only in laboratories.
Vickers hardness testing is mainly used for material research and scientific experiments. Low-load Vickers hardness testing is primarily used for testing the hardness of small precision parts, the hardness and effective depth of surface-hardened layers, and the surface hardness of coatings, etc. Since the test force is very small and the indentation is also very small, the appearance and performance of the specimen remain unaffected.

The hardness testers produced by our Taiwan Nakazawa Co., Ltd. have high precision and stable performance, with a complete range of hardness tester specifications and models suitable for various products and tests across all walks of life.
