About hardness and hardness measurement

Introducing the three main definitions of hardness and the major standard testing methods.

"Hardness" is typically a property of a material that resists plastic deformation when penetrated by another object. It may also refer to rigidity, texture, or resistance to bending, scratching, wear, or cutting. The usual method for obtaining a hardness value is to measure the depth or area of an indentation. There are several key standard testing methods that represent the relationship between the size of the indentation or the rebound velocity and the hardness of a specific material, with Vickers, Rockwell, Brinell, and Leeb being common scales. 【Three Main Definitions of Hardness】 ■ Scratch Hardness Resistance to damage or plastic (permanent) deformation caused by a sharp object. ■ Indentation Hardness Resistance to plastic (permanent) deformation caused by a sharp object. ■ Rebound Hardness In relation to elasticity, the height or speed of the bounce of an object that has fallen on the material. *For more details, please refer to the PDF document or feel free to contact us.
