What group contains the hardest metals known to man?
The hardest element is chromium, which is in group 6.
What treatment is used to make the hardest metals?
A complicate question. The hardest metals are certain alloys treated by certain hardening processes, which differ widely. Tungsten carbide is one of the hardest alloys known; any alloy that passes a spec known as Rockwell C-60, is extremely hard, and there is also Case hardening, and other nitriding processes, to name just a few.
