An Introduction to Rockwell Hardness Testing from www.azom.com There are many rockwell hardness scales, depending on the type of indenter and load used. Data points with the aa note have been provided by the aluminum association, inc. The rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter.
This value has a dramatic effect on both knife edge retention and toughness.
The alloys are classified into the following three groups according as the relation between. Brinell and most scales in rockwell use spherical indenters, which yield geometrically dissimilar. The rockwell hardness scale is typically administered to characterize the hardness of metals, such as thin steel, cemented carbides, lead, aluminum, zinc, copper alloys, titanium, and iron.
