Hardness Test – Micro & Macro Testing

Macrohardness testing using Rockwell hardness method (type C, D,and A) is available for a direct Rockwell hardness number readout and rapid testing time.

Microhardness testing is a method for measuring the hardness of a material on a microscopic scale. A precision diamond square-based pyramid indenter (Vickers hardness scale) is impressed into the material at loads from 10 grams to 1000 grams. The impression length, measured microscopically, and the test load are used to calculate a hardness value. The hardness values obtained are useful indicators of a material’s properties and expected service behaviour.

- Bulk hardness – Randomly-located impressions measure the representative bulk hardness value.

- Localized hardness – Impressions are made at specific sites to determine the hardness at discrete features or phases in the sample.

- Hardness survey – A series of hardness impressions are made along a line from a surface to measure the hardness variation within a sample.

- Thin coatings – The hardness of coatings as thin as a few microns can be determined by measuring directly on the coated surface of a sample.
