2. Key Features & Advantages

C1020 (99.9% Cu) Seamless Tubes

• Ultra-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 Tubes

• Marine-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. Applications

C1020 (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 & Standards

• JIS 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 Assurance

• Seamless 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 Advantages

• Precision 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.
