What factors are unrelated to the advantages of Vickers hardness testers?

A great advantage of the Vickers hardness test is that its hardness value is independent of the magnitude of the test force. As long as the material has uniform hardness, any test force can be chosen arbitrarily, and its hardness value remains unchanged. This is equivalent to having a unified scale within a very broad hardness range. This point is superior to the Rockwell hardness test.
In the medium and low hardness value ranges, on the same uniform material, the Vickers hardness test and the Brinell hardness test results will yield approximate hardness values. For example, when the hardness value is below 400, HV≈HB. 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. When measuring and testing thin and small materials, choosing a Vickers hardness tester for measurement is appropriate.
