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. With the addition of iron, 90/10 copper-nickel alloy tubing performs 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-bore 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.

90/10 Copper-Nickel Alloy Tubing for Heat Exchangers and Condensers
These copper-nickel alloy tubing for heat exchangers and condensers is vital across all industrial sectors. Our company has extensive experience in this field and can supply these tubing in accordance with most international standards and custom requirements.
Properties of Copper-Nickel Brake Tubing
Copper-nickel alloys used for brake tubing typically contain 10% nickel, with iron and manganese additions of 1.4% and 0.8%, respectively. This product conforms to ASTM B466 (American Society for Testing and Materials), which specifies dimensions, tensile strength, and yield strength. Its formability and internal cleanliness meet SAE J527, ASTM A254, and SMMT C5B (Society of Motor Manufacturers and Traders) specifications. Furthermore, this alloy meets the requirements of ISO 4038 (International Organization for Standardization) and SAE J1047 for pressure vessels, fabrication, and corrosion resistance.

C70600 alloy is typically supplied in annealed, heavy-drawn tubing. Its strength and good ductility provide excellent formability.
Because copper-nickel alloys are softer than steel, there were initial concerns about fretting wear. Experience has shown this to be unfounded.
Corrosion Resistance
Before its application as brake tubing, C70600 alloy was used for many years in ships, power plant condensers, and tanker hydraulic piping, demonstrating excellent salt resistance. Early testing showed that the copper-nickel alloy's burst pressure was nearly identical to that of steel. However, after exposure to salt spray for over 180 days, the steel's burst strength decreased significantly. The copper alloy, however, maintained its stable corrosion resistance.
After six months of immersion in a moist, salty mud, brazed steel tubing corroded severely, resulting in wall perforation; however, the copper-nickel alloy tubing only exhibited general surface corrosion. ISO 4038 and SAE J1047, referencing ISO 3768, specify a minimum burst pressure of 110 MPa after 96 hours of testing in neutral salt spray. Swedish standards require corrosion resistance of at least 25% that of zinc. In all cases, C70600 alloy's corrosion resistance far exceeds the standard requirements.
Copper-nickel brake hoses offer exceptional reliability, ensuring increased durability for both manufacturers and vehicle owners, ensuring efficient, long-life braking systems.
