Product Description Product DescriptionUNS C70600 (JIS H3300 C7060) Copper-Nickel Alloy Seamless Pipes1. Material CompositionPrimary 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 PropertiesPropertyValueTensile Strength≥380 MPaYield Strength (0.2%)≥125 MPaElongation≥30% (annealed condition)Hardness60-100 HB (Brinell)Thermal Conductivity40-50 W/m·K 3. Key Features & AdvantagesSuperior 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. ApplicationsMarine & 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 StandardsStandardScopeASTM B111/B111MSeamless condenser/heat exchanger tubes.JIS H3300 (C7060)Seamless copper alloy pipes (Japanese Industrial Standard).EN 12451Welded copper-nickel tubes for EU markets.GB/T 8890 (BFe10-1-1)Seamless pipes under Chinese national standards. 6. Manufacturing & Quality AssuranceSeamless 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 AdvantagesCustomization: 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).
