Brinell Vs Rockwell Hardness Test - Compare and Contrast

The Brinell and Rockwell hardness tests can be used to evaluate the hardness of a wide range of metallic materials. When either test is performed accurately to procedure each will produce a reliable hardness rating to compare to other materials. While both the Brinell and Rockwell tests are consistent, they produce values of hardness on different scales from each other due to slightly different methods and analysis.The Rockwell test measures hardness by using diamond cone indenter. The indentation is measured after a lighter initial load is applied and after a heavier load is applied. This test is carried out on a machine that records each depth and calculates the hardness factor. The evaluator must consider the fundamental properties of a sample before it is tested to ensure it is being evaluated using the proper loading. The hardness is reported on one of the scales A through G; depending on what material is being tested and which loading is used in the procedure.
