Material Composition & Key PropertiesParameterC1020 (99.9% Cu)C7060 (CuNi 90/10)Primary ComponentsCu ≥99.9% (high-purity copper)Cu 88-90%, Ni 9-11%, Fe 1-1.8%Tensile Strength≥200 MPa (annealed)≥380 MPa (annealed)Elongation≥30%≥30%Thermal Conductivity390 W/m·K (excellent heat transfer)40-50 W/m·K (balanced conductivity)Corrosion ResistanceResistant to oxidation and acidic environmentsSuperior resistance to seawater, chlorides, and biofouling 2. Key Features & AdvantagesC1020 (99.9% Cu) Seamless TubesUltra-High Purity: Ideal for applications requiring minimal impurities (e.g., semiconductor cooling, medical gas systems).Electrical Conductivity: 100% IACS (International Annealed Copper Standard), perfect for electrical busbars and RF components.Formability: Easily welded, brazed, or bent without cracking.C7060 (CuNi 90/10) Seamless TubesMarine-Grade Durability: Exceptional resistance to seawater corrosion and erosion.Antimicrobial Properties: Inhibits bacterial growth in HVAC and potable water systems.Thermal Stability: Maintains mechanical integrity from -50°C to 200°C. 3. ApplicationsC1020 (99.9% Cu)C7060 (CuNi 90/10)- Electronics: Heat sinks, vacuum tube components- Marine: Condenser tubes, seawater piping, desalination plants- HVAC: Refrigeration coils, heat exchangers- Oil & Gas: Offshore platform cooling systems- Medical: Oxygen delivery systems, sterilizers- Power Generation: Nuclear/thermal plant heat exchangers- Renewable Energy: Solar thermal collectors- Chemical Processing: Acid-resistant heat transfer systems 4. Compliance & StandardsJIS H 3300: Governs dimensions, tolerances, and testing for seamless copper alloy tubes.International Equivalents:C1020: ASTM B68 (pure copper), EN 1057 (CW024A).C7060: ASTM B111 (C70600), EN 12451 (CW352H), GB/T 8890 (BFe10-1-1). 5. Manufacturing & Quality AssuranceSeamless Production Process:C1020: Cold drawing with annealing for optimal ductility.C7060: Extrusion followed by solution annealing to enhance corrosion resistance.Testing Protocols:Hydrostatic pressure testing (per JIS H 3300).Eddy current testing (ECT) for defect detection.Spectrographic analysis to verify chemical composition.Certifications:Mill Test Certificates (MTC) with traceable heat numbers.Compliance with RoHS and REACH for global exports. 6. Competitive AdvantagesPrecision Tolerances:OD: ±0.1 mm (for tubes <50 mm).Wall thickness: ±7.5% (ensures leak-proof performance).Customization:Available in sizes from 6mm to 250mm OD, with custom lengths (straight or coiled).Longevity:C7060 tubes exhibit >20-year service life in marine environments.C1020 tubes resist oxidation degradation in high-temperature applications.
