Being hard doesn't automatically make it good gear material, in fact many gears are made of softer metals...

But, if you want a generic answer "steel"

From wikipedia:
Numerous nonferrous alloys, cast irons, powder-metallurgy and plastics are used in the manufacture of gears. However steels are most commonly used because of their high strength to weight ratio and low cost. Plastic is commonly used where cost or weight is a concern. A properly designed plastic gear can replace steel in many cases because it has many desirable properties, including dirt tolerance, low speed meshing, and the ability to "skip" quite well.[19] Manufacturers have employed plastic gears to make consumer items affordable in items like copy machines, optical storage devices, VCRs, cheap dynamos, consumer audio equipment, servo motors, and printers.

Car gearboxes use hardened steel gears.
Old clocks use brass wheels meshing onto steel pinions. The hard steel wears faster than the brass.
Car differentials used to use bronze worms onto steel gears.
The windmill close to where I live uses wooden gears, I have forgotten the type of wood but holly was used for bearings.
