Aluminum radiators are lighter and cool almost as good as a copper/brass unit does. If they are both new then copper is going to cool better ,but the aluminum is up to 60% lighter.
copper is better
The purpose of a radiator is to transfer heat from the engine to the atmosphere, so radiators need to be made of a material with a high heat transfer coefficient. Aluminum has a high heat transfer coefficient. In other words, aluminum conducts heat very well. There are other materials, such as copper, which conduct even better, but aluminum is more economical to use than copper.
The core is typically copper with aluminum fins
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
most car radiators are copper or aluminum and plastic.
the radiator itself is either aluminum or copper only the tanks are plastic
Copper is a better heat conductor compared to aluminum. Copper has higher thermal conductivity, meaning it can transfer heat more efficiently than aluminum. This is why copper is commonly used in applications that require high heat transfer, such as heat exchangers and cookware.
Radiator cores are typically made from aluminum and brass. Aluminum is used for the tubes and fins, while brass is used for the header and tanks. Aluminum is chosen for its lightweight and heat transfer properties, while brass is chosen for its corrosion resistance and durability.
They used to be copper and steel but now they are made of aluminum and plastic.
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
Between iron, copper, and aluminum, copper is the best, followed by aluminum, and last by iron. Gold is often plated over other metals because it is even better and resists corrosion.
