Product Description
CuNi44 NC050 Foil High-Performance Nickel-Copper Alloy for Electrical & Industrial Use
Product Overview
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.
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
- High Resistivity: 49 ± 2 μΩ*cm at 20°C
- Excellent Formability: High ductility allows for cold rolling to ultra-thin gauges (down to 0.005mm)
- Corrosion Resistance: Resistant to atmospheric corrosion, freshwater, and mild chemical environments
- Thermal Stability: Maintains properties up to 300°C (continuous use)
