Cuprothal 294/CuNi40 Alloy Resistance Waya
Constantan Waya pẹlu irẹwẹsi iwọntunwọnsi ati iwọn otutu kekere coefficent ti resistance pẹlu alapin resistance / iwọn otutu ti tẹ lori ibiti o gbooro ju “manganins”. Constantan tun ṣe afihan resistance ipata to dara julọ ju ọkunrin ganins lọ. Awọn lilo ṣọ lati ni ihamọ si awọn iyika ac.
Constantan waya jẹ tun awọn odi ano ti awọn iru J thermocouple pẹlu Iron jije awọn rere; Iru J thermocouples ti wa ni lilo ninu ooru atọju awọn ohun elo. Bakannaa, o jẹ awọn odi ano ti iru T thermocouple pẹlu OFHC Ejò awọn rere; Iru T thermocouples ni a lo ni awọn iwọn otutu cryogenic.
Awọn alloy jẹ ti kii-oofa. O ti wa ni lilo fun itanna elekitiriki resistor oniyipada ati awọn igara resistor,
potentiometers, alapapo onirin, alapapo kebulu ati awọn maati. Awọn ribbons ti wa ni lilo fun alapapo ti bimetals. Aaye ohun elo miiran jẹ iṣelọpọ ti awọn thermocouples nitori pe o ndagba agbara elekitiromotive giga (EMF) ni ajọṣepọ pẹlu awọn irin miiran.
