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". CuNi44 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.
