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). We’ve arranged common metals in order of hardness in our handy chart and in this list. Our list includes different kinds of metal from metallic elements like silver to common alloys like steel.


“Timing was an extremely important factor for us and we knew no one in America could get a steel building on site quicker than Armstrong Steel - so the choice was easy. With all of the unscrupulous steel building companies out there today, we're glad we chose Armstrong Steel because we got what we paid for and THEN some AND they came through in a pinch!”
