The Rockwell hardness test is the most used and versatile of the hardness tests. For soft materials such as copper alloys, soft steel, and aluminum alloys a 1/16 diameter steel ball is used with a 100-kilogram load and the hardness is read on the B scale.
Microhardness testing is an indentation method for measuring the hardness of a material on a microscopic scale. A precision diamond indenter is impressed into the material at loads from 15 to 1000 gf. The impression length, measured microscopically, and the test load are used to calculate a hardness value.
