NF38 PTC Ni-Fe Alloy Wire for Automotive Aerospace and Industrial Applications, Resistance 0.38

The product exhibits a resistivity of 0.38 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Ni-Fe alloy with NF38 50-55% nickel content is a nickel-iron alloy known for its positive temperature coefficient (PTC) properties, meaning its electrical resistance increases with rising temperature. This characteristic makes the alloy ideal for temperature-sensitive applications requiring stable thermal response and self-regulating behavior. Commonly used in temperature sensors, thermistors, and current-limiting devices, NF38 ensures reliable performance and precise resistance control across a broad temperature range.

The alloy’s moderate electrical resistivity, combined with good thermal stability, enables it to perform consistently in demanding environments. Its high corrosion and oxidation resistance make it well-suited for use in harsh conditions, such as those encountered in automotive, aerospace, and industrial electronics. Additionally, NF38 is effective in battery management systems, where it aids in thermal regulation and overcurrent protection, helping to prevent overheating and improve system safety.

The PTC characteristics of NF38 also allow it to serve as a self-regulating heating element in devices where consistent, temperature-sensitive heating is essential. With its unique thermal response, durability, and reliability, this alloy is a versatile choice for applications across multiple sectors, providing advanced thermal management and protection.

Key features of PTC Ni-Fe alloy with NF38 include:

1. Positive Temperature Coefficient (PTC):

2. Moderate Electrical Resistivity:

With a balanced resistivity, NF38 is suitable for applications requiring controlled resistance, such as thermistors, resistors, and heating elements.

3. Thermal Stability:

The alloy maintains consistent performance across a broad temperature range, ensuring reliability in fluctuating or high-temperature environments.

4. Corrosion Resistance:

NF38 provides resistance to oxidation and corrosion, making it durable and suitable for harsh industrial, automotive, and aerospace environments.

5. High-Temperature Performance:

This alloy can withstand elevated temperatures without significant degradation, making it ideal for high-temperature applications like overcurrent protection devices and self-regulating heating elements.

6. Self-Regulating Properties:

The PTC effect allows NF38 to automatically adjust its resistance based on temperature changes, making it perfect for current-limiting devices and temperature-sensitive applications.

7. Versatility in Applications:

​NF38 is used in various industries, including automotive, aerospace, electronics, and industrial applications, where reliable thermal management, protection, and stability are required.

Applications:

• Torque Sensors
• Magneto-Mechanical Actuators
• Induction Heating
• Miniaturized Motors and Relays
• Transformers and Inductors
• Open-Loop Current Sensors
• Additive Manufacturing

These applications highlight the versatility and importance of NF38 alloy in modern technology and industry, particularly in fields requiring precise control and efficient performance.
