Copper

In modern shipping and seawater desalination industries, equipment reliability and durability are essential. UNS C70600 90/10 copper nickel seamless pipes are high-performance piping materials that offer exceptional corrosion resistance, thermal stability, and mechanical properties. They are an ideal choice for marine cooling systems and seawater desalination equipment. What Is UNS C70600 90/10 Copper Nickel Pipe? UNS C70600, also known as CuNi 90/10 or CuNi10Fe1Mn, is a copper-nickel alloy based on copper with approximately 10% nickel, as well as controlled additions of iron and manganese. The term “90/10” generally refers to the approximate ratio of copper and nickel in the alloy-about 90% copper and 10% nickel. Compared with standard copper pipes or carbon steel pipes, C70600 copper nickel alloy provides superior corrosion resistance in flowing seawater, mildly polluted seawater, saltwater, and certain chloride-containing media. During service, a dense and stable protective film forms on the material surface, improving its long-term performance in marine environments. C70600 copper nickel alloy also offers good thermal conductivity and fabrication properties. It can be welded, bent, expanded, flared, and processed using other conventional pipe fabrication methods. Therefore, it is highly suitable for complex piping layouts in shipbuilding and offshore engineering applications. Main Advantages of C70600 90/10 Copper Nickel Seamless Pipes 1. Outstanding Seawater Corrosion Resistance 90/10 copper nickel alloy performs reliably in both stagnant and flowing seawater. It resists chloride-induced pitting and crevice corrosion and can withstand alternating wet-dry exposure, tidal splash zones, and seawater corrosion. A dense protective surface film forms naturally on the pipe, helping isolate the base material from seawater attack over the long term and significantly reducing the risk of pipe perforation and leakage. 2. Natural Resistance to Marine Biofouling Copper nickel materials naturally inhibit the attachment of marine organisms, including barnacles, algae, and shellfish. This helps reduce biological fouling in pipelines, minimize blockage and heat-transfer efficiency losses, and lower cleaning and maintenance costs. These properties make C70600 pipes particularly suitable for seawater cooling and desalination systems requiring long-term continuous operation. 3. Excellent Heat Transfer Performance C70600 copper nickel pipes offer good thermal conductivity and stable heat- transfer efficiency. They are suitable for marine engine coolers, condensers, seawater desalination heat exchangers, and other heat-transfer equipment, helping cooling and water-production systems operate efficiently and continuously. 4. High Strength and Good Ductility The Pipes provide balanced mechanical properties and can be bent, expanded, and flanged during fabrication. They offer good fatigue resistance and can withstand seawater pressure fluctuations. The seamless structure eliminates potential corrosion concerns associated with longitudinal weld seams, making these pipes suitable for high-pressure seawater piping systems. 5. Long Service Life and Low Maintenance Cost Under properly controlled seawater service conditions, C70600 copper nickel pipes provide a long service life and are less susceptible to unexpected leakage. This helps reduce economic losses caused by shutdowns, inspections, and repairs in vessels and seawater desalination plants. Main Applications Shipbuilding Industry Ship seawater cooling systems Condensers and heat exchangers Ballast water pipelines Main engine and auxiliary engine cooling circuits Piping systems for commercial vessels, offshore support vessels, and research ships Seawater Desalination Projects Heat exchanger Pipe bundles for reverse osmosis systems Multiple-effect distillation (MED) systems Multi-stage flash (MSF) desalination systems Seawater inlet and outlet pipelines Other Marine Engineering Applications Seawater pipelines on offshore platforms Seawater cooling pipelines for coastal power plants Port seawater conveying systems

In marine environments such as shipbuilding, offshore platforms, and seawater transmission systems, piping materials are continuously exposed to severe conditions including seawater corrosion, erosion, marine biofouling, and cyclic temperature changes. Ordinary carbon steel and stainless steel pipes can be prone to rusting, perforation, short service life, and high maintenance costs. C70600 copper-nickel marine piping, also known as 90/10 copper-nickel alloy piping, offers outstanding seawater-corrosion resistance and stable mechanical properties. It is therefore a mainstream choice for marine piping systems and is widely used in ship seawater cooling systems, ballast-water pipelines, fire- fighting lines, and offshore-platform process pipelines. Product Overview This product is a high-quality C70600 copper-nickel alloy seamless pipe, corresponding to Chinese grade BFe10-1-1 (B10 iron cupronickel). It can be manufactured in accordance with international standards such as ASTM B111, ASTM B466, and ASTM B122. Certifications from major classification societies, including CCS, ABS, DNV, LR, BV, and others, can be provided upon customer request. The alloy uses copper as the base metal and contains 9%-11% nickel, 1.0%-1.5% iron, and an appropriate amount of manganese, forming a stable single-phase solid-solution microstructure. Nickel significantly improves corrosion resistance and strength; iron effectively enhances resistance to erosion corrosion caused by flowing seawater; and manganese further improves processing performance and corrosion resistance. Key Advantages of 90/10 Copper-Nickel Pipe 1. Excellent Seawater Corrosion Resistance Copper-nickel alloy quickly forms a dense and stable protective oxide film when exposed to seawater. This film effectively resists pitting corrosion, crevice corrosion, and erosion corrosion caused by high-velocity seawater. The material performs reliably in both stagnant and flowing seawater, greatly reducing the risk of leakage. It also naturally inhibits the attachment of marine organisms such as barnacles, shellfish, and algae, reducing pipeline blockage caused by biofouling and lowering cleaning and maintenance frequency. 2. Stable Mechanical Properties C70600 copper-nickel pipe has good tensile strength and toughness. It is not prone to brittle fracture under low-temperature conditions and performs well under vibration, impact, and cyclic loads encountered during vessel operation. The material also offers excellent fabrication performance and supports bending, welding, and expanding, making on-site installation convenient. 3. Good Thermal Conductivity Its good thermal conductivity makes it suitable for ship seawater cooling systems. Heat-transfer efficiency remains stable during long-term operation, without the performance degradation caused by rust or severe corrosion, helping ensure the reliable operation of marine power systems. 4. Fatigue Resistance and Long Service Life Compared with carbon steel piping, C70600 copper-nickel pipe provides a longer service life in marine environments. It reduces shutdown time, inspection requirements, replacement frequency, and overall maintenance costs, making it especially suitable for long-term offshore operations. 5. Natural Resistance to Marine Biofouling In natural seawater, C70600 continuously releases trace amounts of copper ions, effectively inhibiting the growth and attachment of barnacles, shellfish, and other marine organisms. This can significantly reduce the need for chemical anti-fouling treatment and pipeline cleaning. 6. Excellent Weldability and Fabrication Performance C70600 can be reliably joined using TIG or MIG welding processes. ERCuNi welding wire with argon shielding gas is recommended. The material is also suitable for cold drawing, rolling, stamping, and other forming processes.

Glid Copper (Dispersion-strengthened copper alloy), also known as alumina copper, is a copper alloy that is dispersed and strengthened by nano-sized alumina particles. It has high strength, high hardness, high wear resistance, high electrical conductivity, and high thermal conductivity. In particular, its excellent high temperature performance is unmatched in copper alloys, and it maintains high strength at 900 °C. After 20 hours of 950-degree heat treatment, the metallographic structure shows no change, and the tensile strength only decreases. 8%, the hardness is only reduced by 3%, so Glid Copper will show great advantages when used at high temperatures or subjected to high temperature treatment!
