Metal Hardness Scale – A Chart of the Mohs Scale of Hardness
This metal hardness chart organizes different types of metal using the Mohs hardness scale. With a diamond being at the top of the scale with a score of 10, elements and alloys can fall along the metal hardness scale from 10 to 1 being the softest.

How to Test the Hardness of Zinc
IV. Is Zinc Softer than Copper? Copper is harder than zinc, but not by much. The Brinell hardness of copper is slightly higher than the Brinell hardness of zinc. Very high-purity copper can also be quite soft because it contains no alloying elements that give it extra hardness.
