A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

Fundamentally, hardness testing determines the resistance a material exhibits in response to the permanent deformation of another material’s penetration. If I take a piece of metal and rub something ...

Although some people may consider it to be â low tech,â using pencils to test hardness is still a method used by many coatings manufacturers and some finishing shops. The test uses special pencils ...

All of our testing is conducted in our lab in Reno, Nevada by experimental researchers who have the experience to develop a customized approach to the specific materials and questions you have. We ...
