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 ...

The medical device and electronics industries manufacture products that are fundamentally different from ordinary hard goods. These high-technology products with critical end-use applications tend to ...

Hardness Testing provides a thorough overview of the most common hardness testing methods, including Rockwell, Brinell, Vickers, Knoop, rebound, and ultrasonic tests. This class presents a description ...

When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...
