radiators need to dissapate heat, and metal can dissapate heat quickly
In the early days radiators were made of brass and copper due to the superior heat dissipation the metals provide, they were very heavy and were soldered together. Newer cars have radiators made of aluminum with plastic/composite tanks mostly because it's cheaper and easier to manufacture and also because they are lighter, and the lighter the car is the better MPG and tail pipe emissions they will have.
Metal has a high co-efficient of expansion and would show the wrong temperature by expanding to give more volume in relation to glass on heating and opposite effect when cooling
Material with low specific heat capacity and with blackened surface are good for radiators.
The entire purpose of an automotive radiator is to move heat away from the engine. To move heat you must have a substance that can conduct heat rapidly and effectively. Substances such as plastics are poor heat conductors on the other hand metals at large are great heat conductors especially copper and aluminum. (that is also why you see many cooking pots and pans made out of copper and aluminum) Older radiators were made almost entirely of copper, they were very effective and relatively cheap at the time, now-days they are almost always made of aluminum because copper has become very cost prohibitive and aluminum is of course lighter.
The metal in a fridge door is made from sheet metal. The sheet metal is either clinched or welded together.
Radiators are made of a lot of metals with high melting points (example: Aluminum)
Metal is used to make radiators primarily because of its excellent heat-conducting qualities. Due to their high thermal conductivity, metals like steel and aluminum can effectively transfer heat from the radiator's hot water or steam to the air around it. This guarantees the room's efficient heating. Metals are also strong and resistant to changes in pressure and temperature inside heating systems. Additionally, because of their malleability, radiators can be shaped into a variety of sizes and designs, giving them versatility in terms of installation and design.
car radiators used to be made of copper, copper doesnt rust. most radiators are now made from aluminum.aluminum also does no rust
a kettle is made out of metal
Wire, an internal heating element and metal, that's about it.
radiators.
Because metals are good heat conductors !

No, they used to be made from copper or brass.
Some metals are naturally malleable, but most metals can be made more malleable by heating it to high temperature.
most car radiators are copper or aluminum and plastic.
