Magnetite's hardness is rated at 5.5 - 6.5, while diamond's hardness is rated at 10 on the Mohs scale -- 10 being the hardest.
So, no.
Diamond is harder than iron. Diamond is the hardest known natural mineral and can scratch iron.
Boron nitride is a synthetic material that is harder than diamond. It exhibits similar properties to diamond but has a higher hardness level.
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
Yes, diamond is harder than any metal. Diamond is the hardest natural material known, ranking 10 on the Mohs scale of mineral hardness, while metals generally rank much lower on the scale.
No. Diamond is the hardest mineral. It measures 10 on the Mohs scale: Corundum measures 9, which is less hard than diamond, as below.
magnetite is harder than galena. Magnetite has a hardness just under glass, so around 5. Galena sits at around 4 on mohs hardness scale
No. Diamond is harder than emerald.
