Product Desciption

NiFe ferronickel PTC alloy wires :

PTC alloy wires has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. Its main features: temperature self-regulating, power self-regulating, constant current, limiting current, save energy, long term service lift.

The PTC alloy wires Chemical composition:

Name	Code	Main Composition(%)
Temperature Sensitive Resistance alloy wire	PTC	Fe	S	Ni	C	P	Standard
Temperature Sensitive Resistance alloy wire	PTC	Bal.	≤0.01	77~82	≤0.05	≤0.01	Q/320421PTC4500-2008

If you need other chemical composition PTC alloy wires, please feel free to let us know. We are glad to customize for you. The temperature Coefficient of resistance and resistivity can be adjusted.
