ʻO Constantan Wire me ka resistivity kaulike a me ke coefficient haʻahaʻa o ke kū'ē ʻana me kahi piʻo kū'ē/mahana pālahalaha ma luna o kahi ākea ākea ma mua o nā "manganins". Hōʻike pū ʻo Constantan i ke kū'ē ʻana i ka palaho ma mua o nā man ganins. Hoʻohana pinepine ʻia nā hoʻohana i nā kaapuni ac.
ʻO ke kaula Constantan kekahi mea maikaʻi ʻole o ka thermocouple ʻano J me ka hao ka mea maikaʻi; hoʻohana ʻia nā thermocouple ʻano J i nā noi mālama wela. Eia kekahi, ʻo ia ka mea maikaʻi ʻole o ka thermocouple ʻano T me OFHC Copper ka mea maikaʻi; hoʻohana ʻia nā thermocouple ʻano T i nā mahana cryogenic.
