This product is a seamless pipe made from Copper-Nickel Alloy UNS C70600 (commonly known as CuNi 90/10), manufactured in strict accordance with the ASTM B466 / B466M standard. This specification covers seamless copper-nickel pipes and tubes for general engineering purposes. As a seamless product, it is manufactured from cast billets by processes like hot extrusion or piercing, followed by cold working and annealing, ensuring high integrity and uniformity without a welded seam.
The alloy is renowned for its excellent corrosion resistance in seawater and marine environments, making it a superior and cost-effective choice over stainless steel in applications prone to chloride stress-corrosion cracking. It offers a balanced combination of good fabricability, moderate strength, and high resistance to biofouling and various forms of corrosion.
Copper-Nickel UNS C70600, or CuNi 90/10, is a single-phase alpha-structured alloy. Its excellent seawater corrosion resistance is attributed to the significant presence of iron and manganese. The typical chemical composition is as follows:
| Element | Content (%) |
|---|---|
| Copper (Cu) | Remainder (approx. 88.7%) |
| Nickel (Ni) | 9.0 - 11.0 |
| Iron (Fe) | 1.0 - 1.8 |
| Manganese (Mn) | ≤ 1.0 |
Note: Other trace elements are controlled to specified limits per relevant standards.
The mechanical properties can vary depending on the temper condition (e.g., soft annealed, hard drawn).
| Property | Metric Value | Imperial Value |
|---|---|---|
| Tensile Strength, Ultimate | 303 - 414 MPa | 43.9 - 60 ksi |
| Tensile Strength, Yield | 110 - 393 MPa | 16 - 57 ksi |
| Elongation at Break | Up to 42% | Up to 42% |
| Density | 8.94 g/cm³ | 0.323 lb/in³ |
Due to its proven performance, ASTM B466 C70600 pipe is the primary product for commercial marine applications. Key application scenarios include:
Seawater Pipework Systems: For offshore platforms, shipboard services, and desalination plants.
Heat Exchangers & Condensers: In power generation, marine, and coastal facilities.
Hydraulic & Firewater Lines: Especially in offshore and marine environments requiring high reliability.
