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.

Why are central heating radiators made of metal?
radiators need to dissapate heat, and metal can dissapate heat quickly
Why is silver not used in central heating radiators?
Silver is a valuable metal, and is thus not used in radiators.
What are radiators made of and why?
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.
When were radiators invented?
Radiators were invented in 1855
What material is a radiator made of?
Material with low specific heat capacity and with blackened surface are good for radiators.
What metal made of radiator?
Radiators are made of a lot of metals with high melting points (example: Aluminum)
Why are central heating radiators made of metal?
radiators need to dissapate heat, and metal can dissapate heat quickly
Why don't car radiators rust?
car radiators used to be made of copper, copper doesnt rust. most radiators are now made from aluminum.aluminum also does no rust
What is a car radiator made of?
most car radiators are copper or aluminum and plastic.
What is car radiator made out of?
Older vehicles had copper and steel radiators, newer vehicles are made of aluminum and plastic.
Why is silver not used in central heating radiators?
Silver is a valuable metal, and is thus not used in radiators.
Which metal is used for making radiators of cars?
Aluminum
Which car manufacturers use cast iron radiators?
Almost all car manufacturers have used cast iron radiators at one time or another, however most are now made of an aluminum alloy that can cool the water intake quickly.
What material is a radiator in a car made from and why?
Most newer cars radiators are made of aluminum to save weight and it dissipates heat more effeciently
What metal is used in central heating radiators?
aluminum and copper
Why is water used as a coolant in car radiators?
Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any other substance. That is why it is used as coolant in car radiators
Are the surfaces of car radiators dull or shiny?
Most car radiators are black as black radiates heat more efficiently than any other color.
