90/10 Copper-Nickel Alloy Tubing
GNEE manufactures copper-nickel alloy tubing that offers excellent resistance to seawater corrosion, as well as high resistance to erosion-corrosion and air impact corrosion. The addition of iron allows 90/10 copper-nickel alloy tubing to perform comparable to 70/30 copper-nickel alloy tubing in seawater heat exchangers. These tubings offer good strength and ductility at room temperature, while exhibiting enhanced strength and other mechanical properties at elevated temperatures.
These copper-nickel alloy tubing is widely used in condensers, coolers, and heat exchangers, where corrosion and erosion resistance are critical while maintaining high thermal conductivity. It is particularly well-suited for marine environments. The multi-layer protective film formed in flowing seawater effectively resists fouling by marine organisms.
These copper-nickel alloy tubing is available in a variety of outer diameters, wall thicknesses, and tempering conditions to achieve the desired mechanical properties and grain size. The mechanical and dimensional characteristics of our products enable us to meet the most demanding orders and exacting tolerances.
70/30 Copper-Nickel Alloy Tubing
GNEE offers the highest standard 70/30 smooth ID copper-nickel alloy tubing, rigorously tested to ensure it meets the stringent requirements of condensers and heat exchangers. These copper-nickel alloy tubes offer exceptional resistance to stress corrosion cracking. We offer a wide range of outer diameters, wall thicknesses, and tempers to meet diverse requirements. Excellent dimensional control and specialized mechanical properties ensure trouble-free operation and cost savings.
Due to its excellent corrosion resistance and near-invulnerability to stress corrosion, these copper-nickel alloy tubes maintain an optimal service life even under the harshest conditions. These copper-nickel alloy tubes are suitable for heat exchangers subject to severe erosion and corrosion, particularly in environments with high temperatures, high velocities, and highly turbulent circulating media. These copper-nickel alloy tubes are not only critical to heat exchanger performance, but also to the cost and lead time of the condensers and heat exchangers in which they are used.

Cupro Nickel Tubes 90/10 for Automobile Industries
The Move To Copper-Nickel Tubing
Copper had been proved since the early days to have many good attributes. It was easy to bend and had very high corrosion resistance, but there was concern about its low corrosion-fatigue strength. When copper-nickel was introduced, it displayed corrosion resistance similar to copper, higher general strength and better fatigue strength. Good formability allows ease of flaring and bending, and although the metal cost is greater than that of steel alternatives, copper-nickel is very attractive in view of its extra life, trouble-free installation and ety/reliability characteristics.
Properties of Copper-Nickel Brake Tubing
The copper-nickel alloy used for brake tubing typically contains 10% nickel, with iron and manganese additions of 1.4% and 0.8% respectively. The product conforms to ASTM B466 (American Society for Testing and Materials), which specifies dimensions, tensile strength and yield strength. Formability and internal cleanliness conform to specifications SAE J527, ASTM A254 and SMMT C5B (Society of Motor Manufacturers and Traders). Also, the alloy meets the requirements for pressure containment, fabrication and corrosion resistance for ISO 4038 (International Standards Organization) and SAE J1047.

Alloy C70600 is normally supplied as redrawn tubing in the annealed condition. The combination of strength and good ductility give excellent formability.
Corrosion Resistance
For many years prior to its application as a brake tubing material, alloy C70600 had been used in ships, power station condensers and hydraulic lines on tankers, and had displayed excellent resistance to saline conditions. Early tests revealed that copper-nickel has almost the same resistance to burst pressure as steel. In testing, however, when exposed to salt spray over 180 days, steel's burst strength decreases significantly. The copper alloy remains consistently resistant.
For tubes covered with a moist, salty mudpack for six months, brazed steel was severely corroded resulting in perforation of the tubing wall; whereas, only superficial general corrosion was found on the copper-nickel tubing. ISO 4038 and SAE J1047 include a corrosion resistance requirement referring to ISO 3768 asking for a minimum burst pressure of 110 MPa after 96 hours in neutral salt spray. Swedish requirements include a resistance at least equal to 25 of zinc. In all cases alloy C70600 easily exceeds the required corrosion resistance.
Copper-nickel brake tubing provides superior reliability and assures both manufacturers and vehicle owners improved durability for effective long-life functioning of the brake system.
