Copper Nickel 66/30/2/2 tubes, also called C70600 tubes, are engineered with a superior combination of properties designed to suit industry applications. Composed of 66% copper, 30% nickel, 2% iron, and 2% manganese, these tubes boast exceptional corrosion resistance, thermal conductivity, and mechanical strength, which are suitable for use across many industries.

Composition and Characteristics

The composition of copper Nickel 66/30/2/2 tubes is essential in defining their outstanding properties. Boasting an impressive 66% copper content, these tubes inherit their inherent conductivity while being strengthened by adding nickel, iron and manganese. Nickel contributes particularly well in marine environments where saltwater exposure may be prevalent, while iron and manganese contribute overall mechanical strength and durability, guaranteeing reliable performance even under adverse conditions.

Features and Benefits

Copper Nickel 66/30/2/2 tubes stand out due to their exceptional corrosion resistance, making them suitable for applications involving exposure to seawater, brine solutions, or other harsh corrosive environments. Their long lifespan and reduced maintenance costs make these tubes particularly suitable for seawater exposure, brine solutions exposure, or thermal management systems where heat transfer needs to occur efficiently. In addition, these tubes exhibit excellent thermal conductivity, which allows efficient heat transfer in heat exchangers, condensers, and thermal management systems, as well as superior mechanical properties like high tensile strength and good ductility, which ensure structural integrity and dimensional stability even under extreme pressure and temperature conditions.

Copper Nickel 66/30/2/2 tubes find widespread application across many industries due to their diverse properties and applications. Marine applications of epoxy flooring systems typically include shipbuilding, offshore platforms and seawater desalination plants – where corrosion and biofouling resistance are key. Additionally, these tubes are favored in the oil and gas industry for applications such as oil coolers, hydraulic lines, subsea pipelines and coolers that must withstand harsh operating environments. Their excellent thermal conductivity makes Copper Nickel 66/30/2/2 tubes indispensable in HVAC, refrigeration, and power generation facilities where efficient heat transfer is crucial to optimal performance. Furthermore, these versatile tubes have also been useful in chemical processing equipment, desalination plants, and automotive heat exchangers, demonstrating their versatility across various engineering applications.
