Constantan Wire ine mwero resistivity uye yakaderera tembiricha coefficent yekupikisa ine flat kuramba / tembiricha curve pamusoro pehupamhi hwakakura kupfuura "manganins". Constantan anoratidzawo zvirinani corrosion resistance pane murume anoita. Mashandisirwo anowanzo kuve akaganhurirwa kune ac maseketi.
Constantan wire zvakare chinhu chisina kunaka cherudzi rweJ thermocouple ine Iron iri iyo yakanaka; Type J thermocouples inoshandiswa mukupisa kurapa maapplication. Zvakare, ndicho chinhu chisina kunaka cherudzi rweT thermocouple ine OFHC Mhangura iyo yakanaka; mhando T thermocouples anoshandiswa pane cryogenic tembiricha.
Iyo alloy haisi-magnetic. Inoshandiswa kune yemagetsi regenerator's variable resistor uye strain resistor,
potentiometers, waya dzekudziya, tambo dzekudziisa uye mateti. Ribhoni anoshandiswa kupisa bimetals. Imwe ndima yekushandiswa ndeyekugadzira thermocouples nekuti inovandudza yakakwira electromotive simba (EMF) yakabatana nemamwe masimbi.
Copper nickel alloy series: ConstantanCuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
