NF46 PTC Ni-Fe Alloy Wire with Chemical Composition and Diameter Inspection for Stable Performance, Resistance0.46
The product exhibits a resistivity of 0.46 at a temperature of 20°C, with a tolerance range of ±0.02.
PTC Ni-Fe alloy NF46 is valued for its unique combination of magnetic properties and thermal characteristics. This alloy exhibits a very low coercive field, making it ideal for high precision torque sensors. Its magnetic properties can be adjusted by adding elements like copper or chromium, effectively reducing the remanence and the coercive field. NF46 also features a tuned Curie point and Hopkinson peak, which are advantageous for non-contact temperature sensing technology.
The alloy's great plasticity and soft magnetic behavior when austenitic make it suitable for a range of applications, including transformers, synchro-resolvers, and miniaturized motors. Its low Curie point (20 < Tc < 450 °C) is particularly useful in various temperature-sensitive applications. NF46 offers medium saturation polarization at room temperature, contributing to its use in low-frequency inductors and current sensors.
Furthermore, NF46's corrosion resistance and workability allow for the creation of complex shapes and structures, expanding its application range to include gas safety actuators and components for additive manufacturing. Ongoing research continues to enhance the magnetic properties of NF46, promising new potential in technological advancements.
