CuNi44 strip, a high-performance copper-nickel alloy strip developed and manufactured by Huona New Material, features a nominal nickel content of 44% with copper as the base metal. Leveraging our advanced cold-rolling and precision annealing technologies, this strip achieves tight dimensional tolerances and consistent material properties across batches. It integrates exceptional electrical resistance stability, superior corrosion resistance, and excellent formability—striking a perfect balance for precision electrical components, sensor elements, and industrial hardware that demand long-term reliability. As a flagship product in Huona’s alloy strip portfolio, it outperforms lower-nickel copper alloys in stability while maintaining cost-effectiveness for large-scale applications.
Standard Designations
Alloy Grade: CuNi44 (Copper-Nickel 44)
UNS Number: C71500
International Standards: Complies with DIN 17664, ASTM B122, and GB/T 2059
Form: Rolled flat strip (custom profiles available upon request)
Manufacturer: Huona New Material, certified to ISO 9001 and RoHS for quality and environmental compliance
Key Advantages (vs. Similar Alloys)
CuNi44 strip stands out in the copper-nickel alloy family for its targeted performance advantages:
Ultra-Stable Electrical Resistance: Resistivity of 49 ± 2 μΩ·cm at 20°C and low temperature coefficient of resistance (TCR: ±40 ppm/°C, -50°C to 150°C)—far superior to CuNi30 (TCR ±50 ppm/°C) and pure copper, ensuring minimal resistance drift in precision measurement equipment.
Superior Corrosion Resistance: Withstands atmospheric corrosion, freshwater, and mild chemical environments; passes 1000-hour ASTM B117 salt spray testing with negligible oxidation, outperforming brass and bronze in harsh industrial settings.
Excellent Formability: High ductility enables cold rolling to thin gauges (0.01mm) and complex stamping (e.g., resistor grids, sensor clips) without cracking—more workable than high-hardness alloy strips like CuNi50.
Balanced Mechanical Properties: Tensile strength of 450-550 MPa (annealed) and elongation ≥25% strike a harmony between structural stability and processability, suitable for both load-bearing and precision-machined components.
Cost-Effective Precision: Offers performance comparable to precious metal alloys (e.g., manganin) at a lower cost, making it ideal for mass-produced precision electrical parts.
Excellent (compatible with CNC cutting, stamping, bending, and etching)
Weldability
Suitable for TIG/MIG welding and soldering (forms corrosion-resistant joints)
Packaging
Vacuum-sealed in anti-oxidation 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: Precision wirewound resistors, current shunts, and potentiometer elements—critical for power meters and calibration equipment.
Sensors & Instrumentation: Strain gauge grids, temperature sensor substrates, and pressure transducers (stable resistance ensures measurement accuracy).
Industrial Hardware: Corrosion-resistant clips, terminals, and connectors for marine, chemical, and HVAC systems.
Medical Devices: Miniature components in diagnostic equipment and wearable sensors (biocompatible and corrosion-resistant).
Aerospace & Automotive: Low-power heating elements and electrical contacts in avionics and electric vehicle control systems.
Huona New Material implements strict quality control for CuNi44 strip: each batch undergoes XRF chemical composition analysis, mechanical property testing (tensile, hardness), and dimensional inspection (laser micrometry). Free samples (100mm×100mm) and material test reports (MTR) are available upon request. Our technical team provides tailored support—including temper selection for stamping, etching parameter optimization, and corrosion protection recommendations—to help customers maximize the performance of CuNi44 in their applications.
