    SGS NF25 Ni60-65 PTC Nickel Mig Wire NiFe Alloy Wire For Electric Blanket

    NF25 Nickel Content 60-65% PTC Ni-Fe Alloy Wire for Electric Blanket, Resistance 0.25


    PTC Ni-Fe alloy NF25 is a nickel-iron alloy with approximately 60% nickel and 40% iron, known for its positive temperature coefficient (PTC) properties. As the temperature increases, NF25’s electrical resistance rises, making it ideal for temperature-sensitive and self-regulating applications. This unique property allows Ni-60 to be effectively used in various industrial, automotive, and electronic applications where thermal stability and precise temperature response are essential.


    The alloy’s moderate electrical resistivity, high-temperature tolerance, and good corrosion resistance make it suitable for components like current limiters, temperature sensors, thermistors, and self-regulating heating elements. In particular, NF25 is valued in applications such as overcurrent protection devices and battery management systems, as well as in automotive and aerospace electronics that demand consistent performance in extreme conditions.


    NF25’s reliability in fluctuating or high-temperature environments makes it versatile and useful for a range of applications requiring robust thermal control and protection. These qualities make NF25 a preferred choice for industries focused on safety and precision in thermal and electrical regulation.

    Key features of the PTC Ni-Fe alloy NF25 include:

    1. Positive Temperature Coefficient (PTC): NF25’s resistance increases with temperature, making it ideal for applications requiring self-regulating heating or temperature-sensitive components.
    2. Balanced Electrical Resistivity: With a suitable level of resistivity, NF25 is effective for current-limiting devices and heating applications where controlled resistance is essential.
    3. Good Thermal Stability: NF25 maintains consistent performance over a wide temperature range, offering reliable behavior in temperature-variable environments.
    4. Corrosion Resistance: This alloy is resistant to oxidation and corrosion, making it suitable for use in challenging or humid environments.
    5. High-Temperature Endurance: NF25retains its structural integrity and functionality at high temperatures, allowing it to be used in applications with demanding thermal requirements.
    6. Versatile Application Range: Its properties make NF25 well-suited for temperature sensors, current limiters, heating elements, and thermal protection devices, used across industries such as automotive, electronics, and industrial manufacturing.

    These features make NF25 a durable and adaptable choice for applications requiring stable and responsive thermal behavior.


    Applications:

    • Temperature Sensors

    Due to its PTC behavior, NF25 is widely used in temperature sensors for automotive, industrial, and HVAC systems where resistance change can be monitored to track temperature shifts accurately.

    • Current Limiting Devices

    NF25’s positive temperature coefficient allows it to act as a self-regulating current limiter, making it suitable for applications requiring overcurrent protection in circuits and electrical systems.

    • Heating Elements and Thermistors

    NF25 is used in self-regulating heating elements and thermistors, providing consistent heat generation and control in appliances, climate control systems, and industrial heating applications.

    • Overload Protection Components

    The alloy’s increasing resistance with temperature helps prevent electrical overloads, making it useful in fuses, circuit breakers, and other protective devices.

    • Battery Management Systems

    In electric vehicles and other battery-powered equipment, NF25 assists with thermal regulation to maintain safe and stable battery temperatures.

    • Aerospace and Automotive Electronics

    NF25’s durability in high-temperature environments makes it valuable for electronic components and sensors in aerospace and automotive sectors, where materials need to perform reliably under extreme conditions.


    These applications leverage NF25’s stable thermal response, PTC characteristics, and resilience, making it a versatile choice for industries requiring precise thermal and electrical control.
