The Hardness of Metals: A Visual Representation of Mohs Scale
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 a diamond (made of carbon) being at the top of the scale with a score of 10, elements and alloys can fall along the metal hardness scale from 10 (being the most scratch-resistant) to 1 (being the softest). Explore the hardness of metals that are elements, like silver, copper, and nickel, next to alloys like bronze, brass, or titanium carbide. We use different kinds of metal for wildly different purposes, and their comparative softness and pliability have been both useful and aggravating throughout history. Think about this: What are the types of metals used for jewelry, circuit boards, or even metal buildings? The Mohs scale of hardness doesn’t necessarily indicate toughness, which is its own metric, but it can give a hint as to which metal types have been the most useful and for which purposes. In addition to listing the Mohs scale scores, the most common uses for each metal, and the element names, we also listed what kind of metal each one is on the periodic table.
