You asked: What is Earth’s hardest material?

(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.

Is anything harder than diamond?

Diamonds remain the most scratch-resistant material known to humanity. … The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.

Which is harder diamond or iron?

Typical values of tensile strength of iron/steel varies from 100 to 11000 MPa. Therefore diamond can withstand more than iron/steel. The data you quote shows that diamond is stronger than steel, but strength isn’t the same as brittleness (or, indeed, stiffness).
