Applications
Because of the wide test force range the Brinell test can be used on almost any metallic material. The part size is only limited by the testing instrument's capacity.
Strengths
- One scale covers the entire hardness range, although comparable results can only be obtained if the ball size and test force relationship is the same.
- A wide range of test forces and ball sizes to suit every application.
- Nondestructive, sample can normally be reused.
Weaknesses
- The main drawback of the Brinell test is the need to optically measure the indent size. This requires that the test point be finished well enough to make an accurate measurement.
- Slow. Testing can take 30 seconds not counting the sample preparation time.
