NF36 PTC Ni-Fe Alloy Wire for Current-Limiting Components in Industrial and Commercial Circuits,Resistance 0.36


The product exhibits a resistivity of 0.36 at a temperature of 20°C, with a tolerance range of ±0.02.


PTC Ni-Fe alloy NF36 is a nickel-iron alloy with a composition range of 50% to 55% nickel and the balance in iron. Known for its positive temperature coefficient (PTC) properties, this alloy’s resistance increases with rising temperature, making it ideal for temperature-sensitive applications. NF36 is particularly valued in industries requiring precise thermal control, such as automotive, aerospace, and industrial electronics. Its moderate electrical resistivity and reliable thermal stability enable it to perform consistently over a wide temperature range, making it suitable for components like temperature sensors, thermistors, and self-regulating heating elements.


The alloy’s corrosion resistance and high-temperature durability also make it a strong candidate for harsh environments, ensuring long-lasting performance under extreme conditions. It’s frequently used in overcurrent protection devices, where the alloy’s resistance change helps prevent overheating by limiting current flow. Additionally, NF36 is utilized in battery management systems and other temperature-control applications, where it enhances safety and efficiency through reliable thermal regulation. With its unique combination of PTC behavior, stability, and resilience, NF36 is a versatile and dependable material for advanced thermal management and protection in various industries.
