Product Description

UNS C70600 (JIS H3300 C7060) Copper-Nickel Alloy Seamless Pipes

1. Material Composition

• Primary Components:

  • Copper (Cu): 88-90% (excellent thermal/electrical conductivity).

  • Nickel (Ni): 9-11% (enhances corrosion resistance and mechanical strength).

  • Iron (Fe): 1-1.8% (improves resistance to erosion and localized corrosion).

  • Manganese (Mn): ≤1% (supports oxidation resistance).

 

2. Key Mechanical Properties

Property	Value
Tensile Strength	≥380 MPa
Yield Strength (0.2%)	≥125 MPa
Elongation	≥30% (annealed condition)
Hardness	60-100 HB (Brinell)
Thermal Conductivity	40-50 W/m·K

 

3. Key Features & Advantages

• Superior Corrosion Resistance:

  • Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brackish water, and acidic environments.

  • Ideal for marine and offshore applications.

• High Thermal Conductivity:

  • Efficient heat transfer in condensers, heat exchangers, and HVAC systems.

• Mechanical Durability:

  • Maintains strength and ductility across a wide temperature range (-50°C to 200°C).

• Microbial Resistance:

  • Naturally inhibits biofouling in marine environments.

 

4. Applications

• Marine & Offshore:

  • Condenser tubes, seawater piping, desalination plants.

• Power Generation:

  • Heat exchangers for nuclear/thermal power stations.

• Oil & Gas:

  • Cooling systems in refineries and petrochemical plants.

• HVAC & Industrial:

  • Chiller tubes, evaporators, and heat recovery systems.

 

5. Compliance with Standards

Standard	Scope
ASTM B111/B111M	Seamless condenser/heat exchanger tubes.
JIS H3300 (C7060)	Seamless copper alloy pipes (Japanese Industrial Standard).
EN 12451	Welded copper-nickel tubes for EU markets.
GB/T 8890 (BFe10-1-1)	Seamless pipes under Chinese national standards.

 

6. Manufacturing & Quality Assurance

• Seamless Tube Production:

  • Extrusion and cold drawing processes ensure uniform wall thickness and surface finish.

• Testing Protocols:

  • Hydrostatic pressure testing, eddy current inspection, and mechanical property validation.

  • Chemical composition verification via spectrographic analysis.

• Certifications:

  • Mill Test Certificates (MTC) per ASTM/EN/JIS requirements.

 

7. Competitive Advantages

• Customization: Available in sizes from 6mm to 250mm OD, with wall thicknesses tailored to project specifications.

• Global Acceptance: Complies with ASTM, JIS, EN, and GB standards for cross-border procurement.

• Long Service Life: Proven performance in harsh environments (e.g., seawater immersion for 20+ years).
