NF13 Nickel85-95 PTC Ni-Fe Alloy Wire for Series Connection and Protection with Accurate Resistance Values, Resistivity 0.13


The PTC Ni-Fe alloy is a Positive Temperature Coefficient (PTC) thermistor made from a combination of Nickel (Ni) and Iron (Fe), designed to exhibit a specific property where its electrical resistance increases as its temperature rises. This makes it ideal for applications involving temperature sensing and self-regulating systems.


PTC behavior is the hallmark of the NF13 alloy. The resistance of this material increases rapidly when its temperature exceeds a certain threshold (the Curie temperature). Below this threshold, the alloy has a relatively low and stable resistance.


This property allows NF13 to function in self-regulating heating elements, where the material limits the current flow through the system as it heats up, preventing overheating.


The high nickel content is responsible for the alloy's thermal stability and magnetic properties, while the iron content contributes to the PTC effect.
This composition provides a good balance between high electrical conductivity (due to nickel) and the temperature-dependent resistivity (due to the iron).

Key features of NF13 PTC Ni-Fe Alloy include:


  1. High Saturation Magnetization: NF13 alloys exhibit higher saturation magnetization compared to pure nickel, which is beneficial for magnetic applications

  2. Lower Coercive Field: These alloys have a lower coercive field, indicating they are easier to magnetize and demagnetize, which is advantageous in applications requiring frequent changes in magnetization


  3. Improved Surface Performance: Ni-Fe alloys, including NF13, show better surface performance, which is crucial in microelectronics and micro-electrical mechanical system applications


  4. Mechanical and Magnetic Properties: The properties of NF13 can be tailored to meet specific requirements, offering a wide range of mechanical and magnetic characteristics


  5. Electrochemical Manufacturability: The alloy can be produced using electrochemical methods, such as electrodeposition, which is cost-effective and versatile


  6. Galvanostatic Pretreatment Benefits: The application of galvanostatic pretreatment (GPT) can improve the surface structure, increase texture strength, reduce crystallite size, and decrease the coercive field of electrochemically manufactured Ni-Fe/ITO thin films, enhancing their magnetic properties


  7. High-Temperature Mechanical Performance: NF13 alloys maintain their mechanical properties at elevated temperatures, making them suitable for high-temperature applications


  8. Oxidation and Corrosion Resistance: These alloys resist oxidation and corrosion at high temperatures, which is essential for applications in gas turbines and industrial furnaces


  9. Precipitation Hardening: Some variations of Ni-Fe alloys, like NF13, can be precipitation hardened to achieve high-yield strength and creep resistance at temperatures up to about 1110°F (600°C)



In summary, PTC Ni-Fe Alloy NF13 is valued for its magnetic properties, high-temperature performance, and corrosion resistance, making it ideal for applications in the aerospace, automotive, and electronics industries.
