Resistance wire is the key factor to determine the quality of electric heating element. Not all the wire can be used to making resistance wire, the resistance wire of electric heating element needs to meet some conditions, so today we come to see the basic requirements of resistance wire in electric heating element.
1, Enough heat resistance, that is, no oxidation or oxidation at high temperature;
2, The smaller the resistivity ,the better.
3, Working for a long time and does not getting old.
4.Good processing performance, can be processed into line, strip or spiral shape, and has good welding performance;
5.Has a certain mechanical strength at high temperature;
6.Bigger than resistance; Otherwise, the tubular heating element will be very long, which is not conducive to installation;
