We used the Mohs scale for mineral hardness, which essentially means how deeply a diamond (which is a 10, the highest number on the scale) could scratch into its surface. It’s the most popular of several indicators of hardness, and not necessarily a rank of toughness, which has its own scale.
Hard and malleable metal alloys like bronze and brass has helped humanity develop tools, weapons, and create civilizations. Now, super-soft metals are essential for modern chip technologies. We listed some of humanity’s most common uses for each metal in addition to its hardness.
Check out this quick picture from AlansFactoryOutlet.com of the different metals of the earth, how humans have used them over the years, and how hard they are!
