LIYI Customized Automatic Digital Brinell Hardness Tester THUS-250
The Brinell hardness tester is mainly used for the hardness measurement of the materials such as cast iron, steel, non-ferrous metal and soft alloy. The Brinell hardness test is a test method with the largest indentation in all hardness tests, which can reflect the comprehensive performance of the material. It is not affected by the micro-segregation and the inhomogeneities of the sample, so it is a high-precision hardness test method.
Brinell hardness tester can be used to test castings, forgings, supplied steel, nonferrous metals and semi-finished steel workpieces subject to tempering and heat treatment. It is a portable instrument which can be used in the workshop. It is easy to operate and easily carry. It can test large workpieces on site without sampling.
The working principle of Brinell hardness tester is to press the steel ball of a certain diameter into the surface of the sample at a certain speed under the action of a certain test force, and to remove the test force after the specified test force is maintained for a specified time. The Brinell hardness of the metal is expressed by the average pressure on the spherical surface area of the indentation.
