At the moment, the market price of copper materials far outweighs the price of aluminum materials. Copper materials are several times more expensive than aluminum materials in terms of cost alone. As a result, in order to save money, many automotive radiator manufacturers and buyers will prefer aluminum car radiators.
2. The difference in welding between copper and aluminum car radiators
Soldering is used to join the copper car radiator for sale. The welding medium is tin, which is achieved by melting and cooling tin, whereas the welding of aluminum car radiators is brazing of aluminum, which uses the different melting points of different aluminum alloys, as well as melting and cooling of the aluminum alloy itself in a specific atmosphere. The aluminum car radiator has no excess components doping, ensuring consistent performance from start to finish.
3. The difference in heat dissipation capacity between copper and aluminum automobile radiators
Copper materials have a relatively high heat dissipation coefficient. Copper products therefore have a higher heat dissipation capacity than aluminum products. However, because welding of copper materials is dependent on the melting and cooling of tin, there is a layer of tin-lead alloy hanging on the surface of the copper car radiator's heat pipe and main sheet. Although copper has a higher heat dissipation coefficient than aluminum, there is a layer of tin-lead alloy between the heat dissipation components, resulting in a much lower overall heat dissipation coefficient for copper car radiators.
