Radiators are made of a lot of metals with high melting points (example: Aluminum)
They are not, car radiators are made out of aluminum. Radiators in your home are made of copper piping surrounded by aluminum heat sinks surrounded by steal cover plates.
It is made of metal because metal is the best conductor of heat.

what are the names of metal
Virgin metal is metal that's been made fresh from ore. Scrap metal is metal that's been made into something first, then brought back and recycled.
Sheet metal refers to how the metal is layed out rather than what type of metal. So therefore sheet metal can be made out of metals such as gold, brass, copper and steel. If the type of metal used is magnetic then so is the sheet metal.
A household radiator is cast iron. An automotive radiator would be aluminum or copper.
if that is not obvious to you, you must be an alien.
Usually a radiator is made of metal. Plastic can not take the pressure. A hole can be fixed by welding. A radiator shop can tell you for sure.
Metal
Your radiator cap is made of metal and rubber. The metal and rubber are reacting to the rust in your radiator. Rust and oxidation in your radiator will deteriorate the cap at an accelerated rate. I suggest flushing the cooling system and replacing the coolant and cap. If it persists after that you might have a heat problem that is cooking the rubber right off the radiator cap. If this is the case you should check your thermostat and heating Coil.
On my 91 it is metal (copper, or an alloy I believe?), although I have never heard of a plastic radiator.
If it is a plastic radiator and it is stripped, no, if it is metal yes.
Follow the 2 small metal lines from the side of the radiator to the transmission
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
The hot water is in contact with the metal casing of the radiator, so that metal radiator takes some heat from the water. The heat then passes from the inside metal of radiator to the outside metal of the radiator through convection. The outside metal of the radiator then passes it to the air that is blowing by it outside.
radiator is the zig zag tubing thing with metal fins in front of the engine block. you will see a metal cap on the center top sometimes on the side.
typically it's located on the left side of the engine bay (if you're standing at the front bumper) it's attached to a plastic tank. It looks nothing like the radiator caps from back in the day that were made of metal and sitting right on top of the radiator itself.
