    Rockwell Hardness Test Methods Of Measuring Copper

    The Rockwell hardness test is the most mon method for determining hardness of ferrous and many nonferrous metals See table below It differs from Brinell hardness testing in that the hardness is determined by the depth of indentation made by a constant load impressing on an indenter In this test a standard minor load is applied to set a hardened steel ball or a diamond cone in the
