ASTM B466 UNS C70600 (CuNi90/10) Seamless Tubes

Introduction

A premium 90% Copper-10% Nickel alloy seamless tube conforming to ASTM B466 standard, designed for extreme corrosion resistance in marine and industrial environments. UNS C70600 is the most widely used copper-nickel alloy for critical fluid transport systems.

 

Key Features

1. Corrosion Resistance

   • Exceptional resistance to seawater corrosion, biofouling, and stress corrosion cracking (SCC).

   • Withstands high-velocity seawater (up to 4 m/s) and sand erosion.

2. Mechanical Properties

   • Tensile Strength: 290-450 MPa (annealed to cold-worked temper).

   • Yield Strength: ≥120 MPa (annealed condition).

3. Thermal Performance

   • Thermal conductivity: 40 W/m·K (ideal for heat exchangers).

   • Operating range: -196°C to +260°C (cryogenic to elevated temps).

4. Fabrication Ease

   • Seamless construction ensures leak-proof performance.

   • Compatible with brazing, welding (TIG/MIG), and bending.

 

Competitive Advantages

 Longer Lifespan

• 3× more durable than carbon steel in seawater applications.

 Low Maintenance

• Self-healing oxide layer prevents pitting and crevice corrosion.

 Cost Efficiency

• 30% lower lifecycle cost vs. titanium or super duplex stainless steel.

 Certified Quality

• Complies with ASTM B466, ASME SB466, EN 12451, and NACE MR0175.

 

Typical Applications

• Offshore & Marine:

  • Seawater cooling pipes, ballast systems, desalination plant tubing.

• Power Generation:

  • Condenser tubes in coastal/nuclear power stations.

• Oil & Gas:

  • Subsea umbilicals, heat exchanger tubes for LNG plants.

• Chemical Processing:

  • Handling brines, acids, and alkaline solutions.

 

Technical Specifications

Parameter	Value
Composition	Cu 88.6%, Ni 10%, Fe 1.4%, Mn 0.1%
Size Range	3mm to 300mm OD, wall thickness 0.5mm-10mm
Surface Finish	Pickled, polished, or bare (as required)
Pressure Rating	Up to PN40 (customizable)

 

Why Choose C70600 Tubes?

• Proven Reliability: Used in North Sea platforms and US Navy vessels.

• Custom Solutions: Available in U-bend, coiled, or straight lengths.

• Full Traceability: Mill test reports (MTRs) per EN 10204 3.1/3.2.
