Ma'anar Constantan
Juriya gami da matsakaici resistivity da ƙananan zafin jiki coefficent na juriya tare da lebur juriya / zazzabi kwana a kan fadi kewayo fiye da "manganins".KuNi44 Alloy waya kuma yana nuna mafi kyawun juriyar lalata fiye da mutumin ganins. Abubuwan amfani sun kasance ana iyakance su zuwa ac da'irori. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Waya kuma shine mummunan kashi na nau'in J thermocouple tare da Iron shine tabbatacce; nau'in J thermocouples ana amfani dashi a aikace-aikacen maganin zafi. Har ila yau, shi ne mummunan kashi na nau'in T thermocouple tare da OFHC Copper tabbatacce; nau'in T thermocouples ana amfani dashi a yanayin zafi na cryogenic.
