The thermal conductivity of C12000 copper tube typically ranges from approximately 391 to 398 watts per meter-kelvin (W/(m·K)) at room temperature (20°C or 68°F). This high thermal conductivity is one of the key properties that make copper, including C12000, an excellent choice for applications requiring efficient heat transfer, such as in HVAC systems, heat exchangers, and refrigeration equipment. Copper’s exceptional ability to conduct heat rapidly and effectively makes it a preferred material in these types of applications where heat exchange is critical.
C12000 copper tube, like many copper alloys, exhibits good corrosion resistance, especially in certain environments. Its corrosion resistance is primarily due to the formation of a protective oxide layer on the surface of the copper, which helps prevent further corrosion. In indoor environments, where moisture levels and exposure to corrosive substances are relatively low, C12000 copper tube is highly resistant to corrosion and can last for many years without issues.
