Brinell Härteprüfmaschine

Brinell Härteprüfmaschine

Brinell is one of the four hardness testing methods; Dr John Brinell invented it in 1900 in Sweden. The Brinell Härteprüfmaschine is mainly used to establish the hardness of substances whose grain structure is too rough for other testing methods such as Rockwell or Vickers. Its ability to reflect the material’s all-around performance without being affected by its variable composition or the microscopic segregation gives it high accuracy.

Product Description

The Brinell hardness tester is used to assess castings, nonferrous metals, supplied steel, forgings and soft alloy material after heat treatment. It is portable and easy to operate. Similarly, this tester can assess large parts minus any sampling and detect significant elements by piece.

It is majorly employed in testing material with an uneven arrangement. In the measurement of small and thin substances, a ball head with a small diameter is used. The primary function of this tester is to reveal raw materials and semi-finished products. It cannot be used for the testing of finished products because of its large indentation.

Using the Brinell Hardness Tester

The functioning of the Brinell Härteprüfmaschine is slightly complex as compared to other hardness testers. It consists of two basic steps as follows:

Step one: Using a given force, press the ball of a specific diameter into an indenter under a given test force rate. Hold the pressure until the specified test force maintain time elapses.

Step two: Calculate the diameter of the indentation produced in a minimum of two perpendicular directions. The average pressure on the indenter expresses the Brinell hardness value.
