45-50% Nickel NF60 PTC Ni-Fe Alloy Wire for Stable and Controlled Thermal

Product Specification

NF60 PTC Ni-Fe Alloy Wire for Stable and Controlled Thermal Responses in Temperature-Sensitive Applications​Resistance 0.6

The product exhibits a resistivity of 0.6 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Ni-Fe alloy NF60, containing 50% nickel and 50% iron, 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.

Key features of PTC Ni-Fe alloy NF60 include:

Applications:

• Temperature Sensors: NF60’s positive temperature coefficient enables it to act as a precise temperature sensor, ideal for automotive, industrial, and HVAC systems.
• Self-Regulating Heating Elements: NF60’s resistance increases with temperature, making it suitable for self-regulating heating elements that provide consistent heat output in appliances and industrial equipment.
• Current Limiting Devices: The alloy is used in current limiters, where its rising resistance with temperature helps regulate current flow, preventing overload in electrical circuits.
• Thermistors: NF60 is utilized in thermistors for temperature measurement and control, particularly in applications requiring sensitivity to temperature changes.
• Overcurrent Protection: NF60 is used in overcurrent protection devices like circuit breakers and fuses, where its resistance response helps prevent excessive current from damaging equipment.
• Battery Management Systems: In electric vehicles and battery-powered equipment, Ni-50 helps regulate temperature to maintain safe operating conditions in battery packs.
• Aerospace and Automotive Electronics: NF60’s thermal stability and durability in extreme conditions make it suitable for electronic components, sensors, and resistors in aerospace and automotive applications.
