Alaabta kululaynta iska caabbinta hoose ee naxaasta ku salaysan ayaa si weyn loogu isticmaalaa xadhkaha wareegga korantada yar, gudbinta kulaylka, iyo alaabta kale ee korantada yar. Waa mid ka mid ah qalabka muhiimka ah ee alaabta korantada ee hooseeya. Qalabka ay soo saartay shirkadeena waxay leeyihiin sifooyin caabbinta wanaagsan ee joogtada ah iyo xasilloonida sare. Waxaan bixin karnaa dhammaan noocyada kala duwan ee silig wareeg ah, siman iyo alaabta xaashida ah.
CuNi40(6J40)
Constantanwaa CuNi40, oo sidoo kale loo yaqaan 6J40, waa daawaha iska caabinta oo inta badan ka samaysan naxaas iyo nikkel.
Waxay leedahay isku-dhafka heerkulka iska caabbinta hooseeya, baaxadda heerkulka shaqada ee ballaaran (500 hoos), hanti mashiineed wanaagsan, alxanka ka-hortagga daxalka iyo alxanka fudud.
Daawaha waa non-magnetic. Waxaa loo isticmaalaa dib-u-dhaqaale koronto-dhaliyaha doorsoome iyo iska caabiyaha cadaadiska
potentiometers, fiilooyinka kululaynta, fiilooyinka kululaynta iyo dermaha. Ribbons waxaa loo isticmaalaa kululaynta bimetals. Qayb kale oo codsi ah ayaa ah soo saarida heerkulbeegyada sababtoo ah waxay soo saartaa xoog koronto oo sarreeya (EMF) iyadoo lala kaashanayo biraha kale.
Taxanaha alwaaxyada Copper:Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
