NF23 PTC Ni-Fe Alloy Ferronickel Wire for Advanced Thermal Management Safety

NF23 PTC Ni-Fe Alloy Ferronickel Wire Resistivity 0.23 for Advanced Thermal Management and Safety Applications

NF23 PTC Ni-Fe Alloy (Ni 60%-65%) is a nickel-iron alloy designed for applications requiring precise temperature regulation, magnetic efficiency, and thermal stability. Its Positive Temperature Coefficient (PTC) ensures resistivity increases with temperature, making it suitable for temperature sensing, overcurrent protection, and self-regulating heating systems.

The alloy offers high magnetic permeability and low coercivity, making it ideal for soft magnetic applications like transformers, inductors, and magnetic shielding. Its thermal stability ensures consistent performance across a broad temperature range, while its moderate nickel content provides good corrosion resistance for durability in various environments.

NF23 is mechanically versatile, featuring good ductility and machinability, allowing it to be fabricated into wires, strips, and other components. It is commonly used in industrial heating systems, precision sensors, magnetic components, and automotive and electronic applications.

With a balance of magnetic, thermal, and resistive properties, NF23 is a reliable and cost-effective material for industrial, automotive, and consumer electronics systems requiring stable performance under varying operating conditions.
