Hardness is a characteristic of a solid material expressing its resistance to permanent deformation. Hardness can be measured on the Rockwell
scale, Brinell scale, or various other scales. When testing metals, indentation hardness correlates linearly with tensile strength. This important
relation permits economically important nondestructive testing of bulk metal deliveries with lightweight, even portable equipment.
