Product Details

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.

Key Features of PTC Ni-Fe Alloy NF52 Include:

 

  1. Low Coercivity:

NF52 has a very low coercive force, which means it can be easily magnetized and demagnetized. This property is crucial for applications involving magnetic sensors and switches.

  1. High Permeability:

The alloy exhibits high magnetic permeability, which allows it to efficiently conduct magnetic lines of force, making it suitable for use in transformers and inductors.

  1. Thermal Stability:

NF52 maintains its magnetic properties over a wide range of temperatures, which is essential for applications that operate in varying thermal environments.

  1. Low Saturation Magnetization:

This feature is beneficial in applications where a controlled magnetic response is required, such as in magnetic shielding and magnetic field sensors.

  1. Corrosion Resistance:
The alloy has good resistance to corrosion, which enhances its durability and reliability in harsh environments.
  1. Workability: 
NF52 is easy to machine and form, allowing for the production of complex parts and components.
  1. Shape Memory Effect:
While not as pronounced as in some other Ni-Fe alloys, Ni45-50 can exhibit shape memory properties, which can be useful in certain applications.
  1. Low Curie Temperature:
The Curie temperature of NF52 is relatively low, which can be advantageous in applications that require a material to lose its magnetic properties at a specific temperature threshold.
  1. Low Magnetic Anisotropy:
The alloy has a low magnetic anisotropy, which means its magnetic properties are consistent in all directions, making it suitable for applications where uniform magnetic behavior is required.
  1. High Electrical Resistivity:
NF52 has a higher electrical resistivity compared to pure iron, which can be beneficial in reducing eddy current losses in electrical applications.
 
These features make NF52 a versatile material for a range of applications, particularly in electronics, aerospace, automotive, and medical industries.
