CuNi44 foil is a high-performance copper-nickel alloy foil with a nominal nickel content of 44%, offering exceptional electrical resistance stability, corrosion resistance, and formability. This precision-engineered foil is produced through advanced rolling processes to achieve tight dimensional tolerances, making it ideal for applications requiring consistent electrical properties and thin-gauge material performance—such as precision resistors, strain gauges, and thermocouple components.
Standard Designations
Alloy Grade: CuNi44 (Copper-Nickel 44)
UNS Number: C71500
DIN Standard: DIN 17664
ASTM Standard: ASTM B122
Key Features
Stable Electrical Resistance: Low temperature coefficient of resistance (TCR) of ±40 ppm/°C (typical) over -50°C to 150°C, ensuring minimal resistance drift in temperature-fluctuating environments.
High Resistivity: 49 ± 2 μΩ·cm at 20°C, suitable for high-precision resistance components.
Excellent Formability: High ductility allows for cold rolling to ultra-thin gauges (down to 0.005mm) and complex stamping without cracking.
Corrosion Resistance: Resistant to atmospheric corrosion, freshwater, and mild chemical environments (complies with ISO 9227 salt spray test for 500 hours with minimal oxidation).
Thermal Stability: Maintains mechanical and electrical properties up to 300°C (continuous use).
