Brinell Hardness Testing

Hardness measurements on gray cast iron reflect the composite values from the matrix material plus graphite; these values are smaller than those of the matrix material. For most types of cast iron, matrix hardness is determined more accurately by Brinell tests than Rockwell tests, though both require correction to obtain true matrix hardness.
