Constantan Alloy Properties
Material Definition
Constantan is a resistance alloy featuring moderate resistivity and low temperature coefficient, maintaining stable resistance across wider temperature ranges than manganin alloys. It offers superior corrosion resistance and is ideal for AC circuit applications.
Available Material Grades
CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi40 (6J40), CuNi44
Key Characteristics
- High specific heat resistance
- Negligible temperature coefficient
- Excellent ductility and formability
- Superior atmospheric corrosion resistance
- Easy soldering and molding capabilities
Electrical Properties
Constantan wire maintains a resistance of 15.94 ohm-cmil/ft with exceptional temperature stability, making it ideal for thermocouples and precision instruments requiring consistent resistance across temperature variations.
