Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

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 ...

• Engineers can use hardness testing to verify the composition or heat-treatment history of materials. • Rockwell, Brinell, Vickers, and Shore are common hardness tests. Their use depends on the ...

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 ...
