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.STM E-10 is a standard test for determining the Brinell hardness of metallic materials. The load applied in this test is usually 3,000, 1,500, or 500 kgf, so that the diameter of the indentation is in the range 2.5 to 6.0 mm. The load is applied steadily without a jerk.
