Why is copper used in radiators?

Copper was used for the original radiators because of the metal's excellent thermal conductivity. This physical property dictates the rate at which a radiator can transfer heat: higher conductivity = faster cooling = higher efficiency, etc.

Likewise, is there copper in radiators?

Copper is actually a better conductor of heat than aluminum. The problem is a copper radiator is not ALL copper. The tubes and fin are copper however they are bonded together with lead, which has horrible heat transfer capabilities. The end tanks are brass and the side channels are steel.

Additionally, why is copper used in heat exchangers? Copper heat exchangers are important in solar thermal heating and cooling systems because of copper's high thermal conductivity, resistance to atmospheric and water corrosion, sealing and joining by soldering, and mechanical strength.

Also to know is, do aluminum radiators cool better than copper?

An aluminum radiator does cool better than a copper brass radiator. For example, an aluminum radiator with 2 rows of 1" tubes is equivalent to a copper brass radiator with 5 rows of 1/2" tubes. Aluminum provides high efficiency, is lightweight, and has a longer life compared to copper brass.

How much can I get for scrap radiator?

If you are removing a radiator from a car you can bring it to the scrap yard as is and get some good money for it, as they usually can get anywhere from $5-30 each depending on the car and type.
