PTC Ni-Fe Alloy NF15 Excellent Electrical Conductivity Magnetic Properties and Corrosion Resistance in One Material

PTC Ni-Fe Alloy Wire NF15 for Different Electric Heaters, Resistivity 0.15

The product exhibits a resistivity of 0.15 at a temperature of 20°C, with a tolerance range of ±0.02.

This alloy is designed to exhibit a marked increase in electrical resistance as its temperature rises, which is a characteristic of PTC materials.The NF15 PTC Ni-Fe alloy is a high-performance Positive Temperature Coefficient (PTC) material. Its key feature is the significant increase in electrical resistance as the temperature rises above the Curie temperature. This makes NF15 ideal for self-regulating heating elements, overcurrent protection, and temperature sensing applications. The alloy offers good thermal stability, corrosion resistance, and mechanical properties, making it suitable for use in electronics, automotive, industrial heating, and electrical protection systems. Its ability to limit current flow as it heats up makes it particularly useful for temperature protection in a wide range of devices and systems.
