NF60 Ferronickel Nife Wire 45-50 PTC Ni-Fe Alloy Rod For Current Overload Protection

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

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

The PTC Ni-Fe alloy NF60, composed of 45%-50% nickel and balenced iron, is a specialized alloy with a positive temperature coefficient (PTC) of resistance, making it well-suited for temperature-sensitive applications. As the temperature rises, NF60’s resistance increases, allowing it to provide stable and controlled thermal responses essential in a range of industrial and electronic applications. Its moderate electrical resistivity, combined with good thermal stability, ensures reliable performance across a wide range of temperatures, making it valuable for applications requiring precise thermal regulation.

NF60 is commonly used in components such as temperature sensors, thermistors, and self-regulating heating elements, where consistent thermal responses are required. The alloy’s durable nature and resistance to corrosion allow it to function effectively in harsh conditions, making it a preferred choice for automotive, aerospace, and industrial electronics. Its ability to withstand elevated temperatures without significant degradation also makes it ideal for current-limiting devices and overcurrent protection components, where it helps safeguard circuits by automatically increasing resistance to limit current flow under high-temperature conditions.

Additionally, NF60 is used in battery management systems and other thermal control systems that require reliable, high-performance materials capable of handling dynamic temperature conditions. Its unique combination of thermal stability, corrosion resistance, and temperature-responsive behavior makes NF60 an adaptable and dependable material across multiple industries for advanced thermal management and protective applications.

Key features of PTC Ni-Fe alloy NF60 include:

1. Positive Temperature Coefficient (PTC)
2. Moderate Electrical Resistivity
3. Thermal Stability
4. Corrosion and Oxidation Resistance
5. High-Temperature Durability
6. Application Versatility

These features make NF60 a reliable, versatile alloy for advanced thermal management, self-regulating heating, and protection applications.

Applications:

• Temperature Sensors
• Self-Regulating Heating Elements
• Current Limiting Devices
• Thermistors
• Overcurrent Protection
• Battery Management Systems
• Aerospace and Automotive Electronics

These applications leverage NF60’s thermal response, reliability, and resistance to environmental stress, making it a valuable material for temperature-sensitive and protective components across various industries.

Q&A:

1. Where can this product be applied?

This product can be used for overload protection. Due to the characteristics of the PTC thermistor, the resistance increases when the device is initially started or when the voltage abnormally increases, thereby protecting downstream devices.

2. How can I pay?

For initial collaborations, we accept T/T and D/P payment methods. However, payment methods may change depending on order volume and years of cooperation.

3. What is the minimum order quantity?

If the product is in stock, we can provide a single unit as a sample. If the product is not in stock, the minimum order quantity is 5kg.

4. How do you guarantee product quality?

We employ advanced manufacturing processes, with three quality inspections during production. We adhere to high-quality standards, consistent with Swedish KANTHAL, and have achieved ISO9001 certification.

5. What are your prices?

We welcome inquiries from our customers. The price of all products is determined by the purchase volume. Based on our market position in China, robust production capacity, and strict standards, our prices are generally lower for the same specifications and quantities.
