F1 brake calipers are made of aluminium.
Here is quotation from the Technical rules:
11.2 Brake calipers:
11.2.1 All brake calipers must be made from aluminium materials with a modulus of elasticity no greater than 80Gpa.
Brake calipers are the hydraulic devices that wrap around the rotors and pinch the brake pads into the rotors when you stop.
NO! Brake Calipers are what compress your Brake Pads on to the rotor which turn simeultaniously with your wheels.
Brake calipers are what house the brake pads and fit over the rotor. If you are working on the brakes, usually the calipers need to be taken off in order to work.

Lift the vehicle on a car jack, remove the tire, remove the brake shoe/calipers, and remove the old brake pads. Put in the new brake pads, replace the brake shoe/calipers, replace the calipers, and lower the car.
You can buy a kit to rebuild the calipers. It is simpler and easier to buy rebuilt calipers.
The maximum tire clearance for the Tektro R559 brake calipers is 32mm.
Brake calipers are what squeeze the brake pads against the brake rotor.
No need to rotate the front caliper pistons as you compress the front calipers. That process is only for the rear calipers because of the parking brake mechanism.
No, brake calipers are not universal and compatible with all types of vehicles. Different vehicles have different brake caliper designs and sizes, so it is important to ensure that the brake calipers you are using are specifically designed for your vehicle make and model.
Yes.
No. If your calipers are leaking, they need to be replaced. Calipers leak because they're worn out, or because you didn't change the fluid and it corroded the inside of the piston bore.
