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 renowned for its exceptionally low coercive field, which makes it exceptionally suitable for applications requiring high magnetic sensitivity, such as precision torque sensors. This alloy's magnetic properties are highly tunable through the addition of elements like copper, chromium, or titanium, which can effectively reduce remanence and the coercive field, enhancing its performance in magnetic applications.

One of the standout features of NF52 is its tuned Curie point and Hopkinson peak, which are critical for the development of new non-contact temperature sensing technologies. This makes the alloy a key material in the advancement of temperature-controlled systems.

In its austenitic form, NF52 exhibits great plasticity and soft magnetic behavior, this characteristic positions it as a strong competitor to cobalt-based amorphous and nanocrystalline materials, which are known for their low coercive fields and high permeabilities. The alloy also features a medium saturation polarization at room temperature, which is crucial for a wide range of magnetic applications.

Key Features of PTC Ni-Fe Alloy NF52 Include:

1. Low Coercive Field: NF52 exhibits a very low coercive field, which can be as low as 2 A/m, making it ideal for high-precision magnetic applications such as torque sensors.
2. Tunable Magnetic Properties: The alloy's magnetic characteristics can be finely adjusted by adding elements like copper, chromium, or titanium, effectively reducing remanence and optimizing performance.
3. Tuned Curie Point: NF52 has a tailored Curie point, which is beneficial for applications in non-contact temperature sensing technologies.
4. Soft Magnetic Behavior: When in the austenitic state, NF52 demonstrates excellent plasticity and soft magnetic behavior, with magnetic anisotropy energies approaching zero at around 80% wt Ni.
5. Medium Saturation Polarization: The alloy features medium saturation polarization at room temperature, which is essential for various magnetic applications.
6. Corrosion Resistance: NF52 offers good corrosion resistance, making it suitable for use in harsh environments.
7. High Workability: The alloy can be easily processed into complex shapes and structures, enhancing its versatility in manufacturing.
8. Competitive Performance: NF52 competes effectively with cobalt-based amorphous and nanocrystalline materials, known for their low coercive fields and high permeabilities.

These features make NF52 a valuable material in various applications, including transformers, synchro-resolvers, low-frequency inductors, and additive manufacturing.
