Applications

Hardness is a characteristic of a material, defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.

The Brinell hardness test method it’s most commonly used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, using a very high test load (3000 kgf) and a 10mm wide indenter so that the resulting indentation averages out most surface and sub-surface inconsistencies.

A Brinell hardness result measures the permanent width of indentation produced by an indenter applied to a test specimen at a given load, for a given length of time. Typically, an indentation is made with a Brinell hardness testing machine and then measured for indentation diameter in a second step with a specially designed Brinell microscope or optical system.

The resulting measurement is converted to a Brinell value using the Brinell formula or a conversion chart based on the formula. Most typically, a Brinell test will use 3000 kgf load with a 10mm ball. If the sample material is aluminum, the test is most frequently performed with a 500 kgf load and 10mm ball.

Features/Advantages

Type B

Qualitest Automatic Radial Arm Brinell Hardness Tester – Model BHD is designed for heavy duty Brinell hardness testing in the most demanding industrial environments. Model BHD type B radial arm Brinell hardness tester with closed loop test head. The machine is extremely robust and will give repeatable and reliable results without operator influence on either the test process or (if integral BRINtronic system option selected) the test results.

The 'C' frame is specifically designed to resist the forces generated in Brinell hardness testing and the bed will take components up to 20 tonnes approximately. The machine bed is 1000mm x 1000mm. The machine clamps the component during testing to ensure that there is no possibility of any movement of either the component or the machine during the test in order to ensure maximum reliability. The machine is capable of performing Brinell hardness tests in all Brinell scales from HBW 2.5/187.5 to HBW 10/3000 and the timing cycle is automatically controlled

Type D

Model BHD type D radial arm Brinell hardness tester with closed loop test head, generally as described but featuring integral BRINtronic fully automatic Brinell microscope to give total operator independence.
