NF23 PTC Ni-Fe Alloy Ferronickel Wire For Electric Blanket, Resistivity 0.23


The product exhibits a resistivity of 0.23 at a temperature of 20°C, with a tolerance range of ±0.02.


The PTC Ni-Fe alloy NF23 is a nickel-iron alloy composed of approximately 65% nickel. Known for its positive temperature coefficient (PTC) properties, this alloy sees its electrical resistance increase as temperature rises, making it ideal for applications where temperature-sensitive resistance is needed. Ni-65’s combination of moderate electrical resistivity, thermal stability, and durability at high temperatures enables it to perform reliably in a range of industrial environments.


NF23 is widely used in applications such as temperature sensors, thermistors, and current-limiting devices, where it ensures precise thermal control and regulation. In addition to its thermal stability, it offers high corrosion and oxidation resistance, which makes it well-suited for harsh environments found in the automotive, aerospace, and industrial sectors. Its robust nature allows it to be employed in overcurrent protection devices, heating elements, and battery management systems, where consistent performance is required under demanding thermal conditions. NiF23’s features make it a versatile and reliable material for advanced thermal management and safety applications across multiple industries.
