C85200 copper tube is a high-performance leaded brass alloy primarily composed of copper (70-74%), zinc (balance), and a small amount of tin (0.8-1.7%). It combines excellent thermal conductivity, corrosion resistance, and mechanical strength. Its unique alloy composition enables outstanding performance in high-temperature, high-pressure environments such as heat exchangers and condensers. It is also easy to process and form, making it suitable for custom applications in complex piping systems.
This copper tube significantly improves heat dissipation efficiency through internal grooves or fins, making it widely used in refrigeration equipment, marine engineering, and the chemical industry. Its wear resistance and stress corrosion resistance extend component life and reduce maintenance costs, while its excellent welding and bending properties further simplify installation, making it an ideal material for industrial heat transfer systems.
