Product Description

PTC ferro-nickel 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
