Constantan Jiki

Uldin Nickel Alloy, wanda yake da saukarwa na lantarki, wanda yake da zafi-zafi-resistant da lalata hali, da sauƙin sarrafa shi da kuma jagorantar da aka makara. Ana amfani dashi don yin mahimman kayan haɗin a cikin ɗaukar nauyin theryrikal, ƙananan tsayayya da fashewa, da kayan aikin lantarki. Hakanan abu ne mai mahimmanci don kebul na dumama na lantarki. Yana kama da na Cupronikel.
