Chromium is the hardest metal; the Mohs hardness of osmium is 7 and the Mohs hardness of chromium is 8,5.
Osmium is one-third as hard as quartz. Tool steels are one-fourth as hard as osmium. Chromium has a oxide layer harder than corundum if dry and sputtered.

osmium
the hardest element is osmium, number 76 on the periodic table.
Yes, osmium is a metal and is conductive.
Osmium is a metal with a blue-gray appearance.
Osmium is the densest metal, and it is very strong and also very heavy. But is mostly used in alloys to increase strength, no pure metal is harder than the strongest of alloys.
Osmium is a solid metal at room temperature.
Osmium is, itself, a transition metal.
Osmium has the highest density among metals so is heaviest metal.
Diamond is the hardest substance known - but it is not a metal it is an arrangement of carbon atoms in a lattice.
