Copper pipe is more corrosion resistant and high temperature resistant than aluminum pipe, better thermal conductivity, but the price is higher; aluminum pipe is lighter and cheaper.
First, the comparison of physical properties
Copper tube has a small coefficient of thermal expansion, high thermal conductivity, heat resistance, so it is widely used in the field of high temperature; and aluminum tubes are lighter than copper tubes, but the thermal conductivity is slightly inferior to copper tubes, so it is more suitable for low-temperature areas, such as air-conditioning refrigeration and so on.
Second, the comparison of chemical properties
Copper tube corrosion resistance is better, not affected by grease and oxidation, while the aluminum tube is relatively easy to corrosion damage. In addition, when the copper pipe in a long time in contact with oxygen in the air, its surface will generate a protective film, which helps prevent corrosion.
Third, the service life of the comparison
The service life of copper pipe is relatively longer, aluminum pipe is relatively short. Copper pipe corrosion resistance and high temperature performance are excellent, which is conducive to improving its service life; and aluminum pipe due to relatively thin, abrasion resistance is not as good as copper pipe, coupled with easy damage due to corrosion, so its service life is relatively short.
Fourth, the comparison of environmental protection
Copper tube recyclable value is relatively higher, can effectively use resources, reduce environmental pollution, in line with the global trend of environmental protection; while the aluminum tube, although the service life is relatively short, but its raw materials can be recycled better, so there is also a good advantage of environmental protection.
Overall, copper and aluminum tubes have their own characteristics. Copper tube is relatively more durable, corrosion and high temperature resistance, better thermal conductivity, but the price is higher; aluminum tube is lighter, cheaper, but thermal conductivity is slightly inferior, easy to corrosion damage. In the choice, need to choose according to the specific application scenarios and needs.
