Smaller aircraft like the cessnas use aluminum skin. Older aircraft use cloth. More modern large aircraft use a honeycomb structure surrounded by aluminum. Some modern fighters use carbon fiber.

Usually from the same materials used in the rest of the airplane. Most today are aluminum. Then most aircraft today are still aluminum skinned.
There are some magnesium surfaces on older Beach aircraft. There are also some that are "plastics" carbon fiber, fiberglass, composites, etc. There are some made from cloth (normally older aircraft or experimental aircraft). So on what aircraft?

The elevator is just another surface on the aircraft even tough it is a "control surface".

Elevators are control surfaces, usually at the rear of an aircraft, which control the aircraft's orientation by changing the pitch of the aircraft, and so also the angle of attack of the wing.

In some aircraft the elevator is in the front, ahead of the wing; this type of configuration is called a canard, the French word for duck. The Wright Brothers' early aircraft were of this type. The canard type is more efficient, since the forward surface produces upward lift. The main wing is also less likely to stall, as the forward control surface is configured to stall before the wing, causing a pitch down and reducing the angle of attack of the wing.

so the first kites used Spruce for the straight spars - aircraft-grade spruce is straight-grained, knot free, and should have a minimum of 14 annual rings per inch. (The tighter the spacing of the annual rings, the stronger and more stable the wood.)

the curved bits were made from Ash (four quarter) straight, clear ash for the bentwood parts and where extra strength is needed, such as the bottom elevator control arms - but there’s a hitch. When bending wood, air-dried lumber is superior to kiln-dried, and most dealers stock kiln-dried only.

the wooden frame was made rigid with lacing cord - waxed twine - 12/3-ply right waxed linen holdfast and covered in 100% "glider cotton" with a thread count of 213. doped to prevent air bleeding.

1940.s planes saw the introduction of steam moulded ply woods to make leading and trailing edges.

1950's planes used alluminuim frames with magnesium plate covering.

by the 60;s, alluminium was standard

in the 80's resin honeycomb coated with alluminium was introduced.

in the 90;s resin compound laminates were introduced.

Elevators have been made with everything from wood and linen fabric to aluminium and honeycomb steel to mylar plastic.the construction is usually of the structual rib with thin skinning type ie the ribs provide the strength/rigidity and the skinning material provides the aerodynamic surface.

It depends on what aircraft you are thinking of. Large commercial jets are using composites for most of the control surfaces.
