NF32 PTC Ni-Fe Alloy High Nickel Mig Wire Resistance For Heaters Custom

NF32 Nickel Content 50-55 PTC Ni-Fe Alloy Wire Rod for Electric Heating Blanket​, Resistance 0.32

The product exhibits a resistivity of 0.32 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Ni-Fe alloy with a nickel content of 50%-55% is a specialized nickel-iron alloy designed for temperature-sensitive applications due to its positive temperature coefficient (PTC) properties. This alloy sees an increase in electrical resistance as temperature rises, making it ideal for applications where precise thermal control is required. With moderate electrical resistivity and high thermal stability, it performs reliably across a wide temperature range, providing stable and predictable responses in various environments.

This Ni-Fe alloy is commonly used in temperature sensors, thermistors, and self-regulating heating elements, where accurate resistance adjustments with temperature are crucial. Its durability, along with strong corrosion and oxidation resistance, allows it to function effectively in demanding conditions, including automotive, aerospace, and industrial applications. Additionally, its PTC behavior makes it valuable in overcurrent protection devices, fuses, and current limiters, where it helps prevent overheating by increasing resistance to control current flow.

In battery management systems, this Ni-Fe alloy aids in thermal regulation, contributing to the safety and efficiency of battery-powered equipment. Overall, Ni-Fe alloy with 50%-55% nickel content is a versatile and robust material for advanced thermal management and protective applications across multiple industries.
