Alloy 294/Cuprothal/Constantan Copper Nickel 40 Waya / Filat Waya fun Alapapo
Constantan rinhoho (CuNi44Mn) Ejò Nickel Electric Resistance Alapapo Ribbon
Constantan Waya Definition
Alloy Resistance pẹlu resistivity iwọntunwọnsi ati iwọn otutu kekere coefficent ti resistance pẹlu alapin resistance / iwọn otutu ti tẹ lori ibiti o gbooro ju “manganins”. CuNi44 Alloy waya tun fihan ipata resistance to dara ju awọn gani ọkunrin. Awọn lilo ṣọ lati ni ihamọ si awọn iyika ac. CuNi44/ CuNi40 /CuNi45 Constantan Ejò Nickel Alloy Waya tun jẹ ẹya odi ti iru J thermocouple pẹlu Iron jẹ 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.
