Description

NF32 Nickel Content 50-55 PTC Ni-Fe Alloy Wire Rod for Electric Heating Blanket​, Resistance 0.32

The product exhibits a resistivity of 0.32 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Ni-Fe alloy with a nickel content of 50%-55% is a specialized nickel-iron alloy designed for temperature-sensitive applications due to its positive temperature coefficient (PTC) properties. This alloy sees an increase in electrical resistance as temperature rises, making it ideal for applications where precise thermal control is required. With moderate electrical resistivity and high thermal stability, it performs reliably across a wide temperature range, providing stable and predictable responses in various environments.

This Ni-Fe alloy is commonly used in temperature sensors, thermistors, and self-regulating heating elements, where accurate resistance adjustments with temperature are crucial. Its durability, along with strong corrosion and oxidation resistance, allows it to function effectively in demanding conditions, including automotive, aerospace, and industrial applications. Additionally, its PTC behavior makes it valuable in overcurrent protection devices, fuses, and current limiters, where it helps prevent overheating by increasing resistance to control current flow.

In battery management systems, this Ni-Fe alloy aids in thermal regulation, contributing to the safety and efficiency of battery-powered equipment. Overall, Ni-Fe alloy with 50%-55% nickel content is a versatile and robust material for advanced thermal management and protective applications across multiple industries.

Some key features of NF32 include:

1. Low Coercive Field:
NF32 alloys can exhibit a very low coercive field, which is beneficial for high precision torque sensors.
2. Tunable Magnetic Properties:
The magnetic properties of these alloys can be tuned by adding elements like copper or chromium & titanium, which effectively reduce the remanence and the coercive field.
3. Curie Point and Hopkinson Peak:
These alloys have a tuned Curie point and Hopkinson peak, which are advantageous for new non-contact temperature sensing technology.
4. Great Plasticity and Soft Magnetic Behavior:
When austenitic, these fcc Fe-Ni materials exhibit great plasticity and very soft magnetic material (SMM) behavior with respect to magnetic anisotropy energies.
5. Low Curie Point:
Industrial austenitic FeNi(Cr,Mo,etc) alloys, which are similar to NF32 are characterized by a low Curie point (20 < Tc < 450 °C).
6. Saturation Polarization:
These alloys have a saturation polarization of medium amplitude at room temperature, which is a significant property for magnetic applications.
7. Shape Memory Effect:
Ni-Fe alloys, in general, are known for their shape memory effect, which is crucial for applications requiring materials that can return to their original shape after deformation.
8. Corrosion Resistance:
Ni-Fe alloys typically offer good corrosion resistance, making them suitable for use in harsh environments.
9. High Workability:
These alloys are often easy to work with, allowing for the creation of complex shapes and structures through processes like high energy ball milling.
10. Potential for Technological Applications:
The ongoing research and development in the field of Fe-Ni alloys, including NF32, are focused on improving their magnetic properties and expanding their applications in various technological fields.
These features make NF32 alloys suitable for a range of applications, including precision sensors, actuators, and components in devices that require specific magnetic properties.
