Descrizione di prodotto
Huona CuNi44/NC050/6J40 Strip Superior Corrosion Resistance
Product Overview

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.

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)
  • 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
  • Superior Corrosion Resistance: Withstands atmospheric corrosion, freshwater, and mild chemical environments; passes 1000-hour ASTM B117 salt spray testing with negligible oxidation
  • Excellent Formability: High ductility enables cold rolling to thin gauges (0.01mm) and complex stamping without cracking
  • Balanced Mechanical Properties: Tensile strength of 450-550 MPa (annealed) and elongation ≥25%
  • Cost-Effective Precision: Offers performance comparable to precious metal alloys at a lower cost

Typical Applications
  • Electrical Components: Precision wirewound resistors, current shunts, and potentiometer elements
  • Sensors & Instrumentation: Strain gauge grids, temperature sensor substrates, and pressure transducers
  • Industrial Hardware: Corrosion-resistant clips, terminals, and connectors for marine, chemical, and HVAC systems
  • Medical Devices: Miniature components in diagnostic equipment and wearable sensors
  • 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.
