ASME SB171 C70600 Copper Nickel Alloy Ring For Seawater Corrosion Resistance
ASME SB171 C70600 Copper Nickel Alloy Ring For Seawater Corrosion Resistance
These ring-shaped industrial components, conforming to ASME SB171 standards and made of seawater-resistant C70600 copper-nickel alloy (90-10 CuNi), are primarily used for sealing or connecting in harsh environments such as marine and desalination plants.
copper-nickel alloy
90-10 copper-nickel alloy (C70600) is a high-performance corrosion-resistant alloy with copper as the base and about 10% nickel and 1-2% iron added.
Its core characteristics are extremely excellent resistance to seawater corrosion, resistance to marine organism adhesion, and good machinability. It is one of the preferred materials for pipelines and key components in ships, seawater desalination plants and marine engineering.
