The Brinell method is suitable for hardness testing of soft metals (light metals, lead, tin) as well as hard metals, such as steel and iron.. Brinell testing of a material with different ball diameters and test forces must be conducted within the same force-diameter index („Brinell test procedure") in order to enable direct comparison of the measured hardness values.
