C77000 copper tube is a high performance copper-nickel-zinc alloy tube with excellent corrosion resistance, high strength and good electrical and thermal conductivity. Its nickel and zinc content significantly improves the resistance to stress corrosion and dezincification, which is particularly suitable for harsh environments such as marine, chemical or industrial atmospheres. At the same time, its tensile strength of up to 700-850 MPa, able to withstand long-term dynamic loads and repeated mechanical stress, suitable for heat exchangers, marine piping, precision mechanical components and other demanding scenarios of strength and durability. In addition, the material has excellent electrical and thermal conductivity, and is often used in electrical equipment and heat dissipation systems.
C77000 copper tube has both excellent hot and cold processing performance, can be cold drawn, extruded and other ways to form a complex tubular structure, and after processing the surface is smooth, dimensional stability, easy to manufacture precision parts. Its weldability and cutting performance are good, reducing processing costs and maintenance difficulties. In addition, the material’s mechanical properties increase rather than decrease at low temperatures (e.g., near absolute zero), making it suitable for special low-temperature engineering applications. With its comprehensive performance advantages, C77000 copper tube is widely used in shipbuilding, energy equipment, chemical piping and high-end instruments, balancing the needs of reliability and functionality.
