Micro-hardness tests provide precise, accurate information for materials that have fine microstructures.
Micro-hardness testing is used for very thin, layered samples of metals and extremely light loads, whereas macro hardness tests such as Brinell, Rockwell and Vickers perform hardness tests using loads typically from 1kgf up to 3000kgf.
Micro-hardness testing is ideal for the following applications:
- Coating hardness
- Surface hardness
- Case depth
- Hardness of fragile or brittle metals
- Microstructural hardness variations
