Description

NF36 PTC Ni-Fe Alloy Wire for Enhanced Safety and Efficiency in Temperature Control Resistance 0.36

NF36 PTC Ni-Fe Alloy (Ni 50%-55%) is a nickel-iron alloy known for its Positive Temperature Coefficient (PTC) behavior, where electrical resistivity increases with rising temperature. This property makes it suitable for temperature sensing, current limiting, and self-regulating heating applications.

The alloy features high magnetic permeability and low coercivity, making it ideal for soft magnetic applications such as transformers, inductors, and magnetic shielding. Its thermal stability ensures reliable performance across wide temperature ranges, while its balanced nickel content provides good corrosion resistance for long-lasting durability.

NF36 is mechanically versatile, offering excellent ductility and machinability for easy fabrication into wires, strips, and other components. It is widely used in industrial heating systems, magnetic cores, overcurrent protection devices, and temperature-sensitive resistors.

With its combination of thermal stability, magnetic efficiency, and corrosion resistance, NF36 is a dependable material for industrial, automotive, and electronic applications requiring precision, durability, and reliable performance under varying environmental conditions.
