Description

Exceptionally Low Coercive Field NF52 PTC Ni-Fe Alloy Wire for Magnetic Sensitivity, Resistivity 0.52

The product exhibits a resistivity of 0.52 at a temperature of 20°C, with a tolerance range of ±0.02.

The PTC Ni-Fe alloy NF52 is celebrated for its remarkably low coercive field, ideal for precision torque sensors. Its magnetic properties are adjustable with the addition of elements like copper, chromium, or titanium, reducing remanence and enhancing performance. The alloy's tuned Curie point and Hopkinson peak are pivotal for non-contact temperature sensing technologies. Exhibiting great plasticity and soft magnetic behavior, NF52 competes with cobalt-based materials in low coercive field applications. Its medium saturation polarization at room temperature is crucial for magnetic applications.
Additionally, NF52 offers corrosion resistance and high workability, making it suitable for a range of applications from transformers to additive manufacturing. Ongoing research aims to further enhance its magnetic properties and expand its technological applications.
