Description

NF60 Nickel Content 45-50 PTC Ni-Fe Alloy Rod For Current Overload Protection, Resistance 0.6

PTC Ni-Fe alloy NF60, containing 45-50% nickel, is known for its positive temperature coefficient (PTC) properties, making it ideal for temperature-sensitive applications. As temperature increases, the electrical resistance of NF60 rises, allowing for stable thermal response and precise regulation. This characteristic is highly valued in applications such as temperature sensors, thermistors, and self-regulating heating elements, where consistent resistance behavior is essential.
NF60 is designed to perform reliably across broad temperature ranges, offering moderate electrical resistivity along with strong thermal and corrosion resistance. These features make it particularly useful in demanding environments, including automotive, aerospace, and industrial electronics, where materials must maintain integrity under harsh conditions.
The alloy is also employed in current-limiting devices and overcurrent protection components, where its temperature-responsive resistance helps prevent overheating by automatically reducing current flow at high temperatures. Additionally, NF60 is widely used in battery management systems and other thermal control applications requiring robust and reliable materials. With its stable thermal performance, durability, and PTC behavior, NF60 is a versatile and dependable alloy for advanced thermal regulation and protection across various industries.
