    NF25 PTC Ni-Fe Alloy Wire Valued in Automotive and Aerospace Electronics for Consistent Performance, Resistance 0.25


    PTC (Positive Temperature Coefficient) Ni-Fe Alloy Ni60-65 is a nickel-iron alloy known for its distinctive property of increasing electrical resistance with temperature. This behavior makes it ideal for applications requiring temperature-sensitive electrical or thermal controls. The alloy contains 60–65% nickel, with the remainder primarily iron, and is engineered to provide high stability and predictable resistance characteristics.
    Ni60-65 exhibits excellent corrosion resistance and mechanical durability, making it suitable for harsh environments. Its positive temperature coefficient allows for self-regulating heating applications, ensuring safety and energy efficiency in devices such as heating elements, circuit breakers, and temperature sensors. The material also sees usage in magnetic shielding due to its favorable permeability and low coercivity.
    This alloy performs well over a broad temperature range and is easy to fabricate into various shapes, including wires and strips. Its consistent electrical performance, combined with environmental robustness, makes it a valuable material in industrial, automotive, and consumer electronics sectors, contributing to energy-efficient and reliable system designs.
