Productomschrijving
Hot Sale CuNi23/NC030 Strip Nickel Copper Alloy for Electrical & Industrial Use
Product Overview
CuNi23 strip, a high-performance copper-nickel alloy strip meticulously crafted by Huona New Material, is engineered with a nominal 23% nickel content balanced with copper as the base metal. Leveraging our advanced rolling and annealing technologies, this strip delivers exceptional electrical resistance stability, corrosion resistance, and formability--making it a preferred choice for precision electrical components, decorative applications, and marine hardware.
Standard Designations
- Alloy Grade: CuNi23 (Copper-Nickel 23)
- UNS Number: C70600
- International Standards: Complies with DIN 17664, ASTM B122, and GB/T 2059
- Form: Rolled strip (flat); custom slit widths available
- Manufacturer: Huona New Material, certified to ISO 9001 for consistent quality control
Key Advantages (vs. Similar Alloys)
- Balanced Resistance & Cost: Resistivity of 35-38 μΩ*cm (20°C)--higher than CuNi10 (45 μΩ*cm, but more costly) and lower than pure copper (1.72 μΩ*cm), making it ideal for mid-precision resistive components without overspending.
- Superior Corrosion Resistance: Outperforms brass and pure copper in saltwater, humid, and mild chemical environments; passes 1000-hour ASTM B117 salt spray testing with minimal oxidation.
- Excellent Formability: High ductility enables cold rolling to ultra-thin gauges (0.01mm) and complex stamping (e.g., precision grids, clips) without cracking--surpassing the workability of high-nickel CuNi44.
- Stable Thermal Properties: Low temperature coefficient of resistance (TCR: ±50 ppm/°C, -40°C to 150°C), ensuring minimal resistance drift in temperature-fluctuating industrial settings.
- Attractive Aesthetic: Natural silvery luster eliminates the need for plating, reducing post-processing costs for decorative and architectural applications.

| Item | Specification |
|---|---|
| Surface Finish | Bright annealed (Ra ≤0.2μm), matte (Ra ≤0.8μm), or polished (Ra ≤0.1μm) |
| Flatness | ≤0.05mm/m (for thickness ≤0.5mm); ≤0.1mm/m (for thickness >0.5mm) |
| Machinability | Excellent (compatible with CNC cutting, stamping, and bending; minimal tool wear) |
| Weldability | Suitable for TIG/MIG welding and soldering (forms strong, corrosion-resistant joints) |
| Packaging | Vacuum-sealed in moisture-proof bags with desiccants; wooden spools (for rolls) or cartons (for cut sheets) |
| Customization | Slitting to narrow widths (≥5mm), cut-to-length pieces, special tempers, or anti-tarnish coating |
Typical Applications
- Electrical Components: Mid-precision resistors, current shunts, and potentiometer elements--where balanced resistance and cost are critical.
- Marine & Coastal Hardware: Boat fittings, valve stems, and sensor housings--resistant to saltwater corrosion without the expense of high-nickel alloys.
- Decorative & Architectural: Nameplates, trim for appliances, and architectural accents--silver luster and corrosion resistance eliminate plating needs.
- Sensors & Instruments: Thermocouple compensation wires and strain gauge substrates--stable electrical properties ensure measurement accuracy.
- Automotive: Connector terminals and small heating elements--combines formability with resistance to underhood humidity.
Huona New Material subjects every batch of CuNi23 strip to rigorous testing, including chemical composition analysis, mechanical property verification, and dimensional inspection. Free samples (100mm×100mm) and material test reports (MTR) are available upon request. Our technical team provides tailored support--such as temper selection for stamping or corrosion protection recommendations--to optimize CuNi23 performance for specific applications.
