ASTM B466 C70600 Seamless CuNi 90/10 Pipe for Seawater Applications
This seamless pipe is manufactured from Copper-Nickel Alloy UNS C70600 (CuNi 90/10) in strict compliance with ASTM B466 / B466M standards. The seamless manufacturing process ensures high integrity and uniformity without welded seams, making it ideal for demanding marine and industrial applications.
Superior Corrosion Resistance
CuNi 90/10 alloy provides excellent corrosion resistance in seawater and marine environments, offering superior performance and cost-effectiveness compared to stainless steel in applications prone to chloride stress-corrosion cracking. The material combines good fabricability, moderate strength, and high resistance to biofouling.
