Test advantages of the hardness tester
Advantage of Brinell hardness test is good for the representation of hardness, because usually used a 10 mm diameter ball indenter, 3000kg test force, the indentation area larger reflect a wide range of metal the comprehensive influence of the average value, and is not influenced by the individual components and tiny uneven degree of influence. It is especially suited to determine the gray cast iron, alloy bearing and with coarse grain metal materials. The test data is stable, good reproducibility, and the measurement accuracy is higher than that of the lower hardness tester, which is lower than that of Vivtorinox. In addition, there is a good corresponding relationship between the hardness and tensile strength.
