This metal hardness chart organizes different types of metal using the Mohs hardness scale, a metric used by scientists to determine the scratch resistance of different minerals. With diamond at the top of the scale at a score of 10, elements and alloys can fall along the metal hardness scale from 10 (the most scratch-resistant) to 1 (the softest).

Also highlighted in this chart are common uses by humans of these elements and alloys, ranging from computing and electronics, jewelry, biomedical and many other uses.
