Aloyi 294/Cuprothal/Constantan Copper Nickel 40 Waya / Waya Wophwathira Wotentha
Mzere wa Constantan (KuNi44Mn) Copper Nickel Electric Resistance Heating Riboni
Constantan Waya Tanthauzo
Resistance alloy yokhala ndi resistivity yapakatikati komanso kutentha pang'ono kofanana ndi kukana kokhotakhota mopanda phokoso / kutentha kopindika mokulirapo kuposa "manganins". Waya wa CuNi44 Alloy amawonetsanso kukana kwa dzimbiri kuposa ma man ganins. Kugwiritsiridwa ntchito kumangogwiritsidwa ntchito pa ma circuit ac. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire ndi chinthu cholakwika cha mtundu J thermocouple ndi Iron kukhala positive; mtundu J thermocouples amagwiritsidwa ntchito pochiza kutentha. Komanso, ndi chinthu choyipa cha mtundu wa T thermocouple wokhala ndi OFHC Copper zabwino; mtundu wa T thermocouples amagwiritsidwa ntchito pa kutentha kwa cryogenic.

Zogulitsa:
1) Anti-oxidation yabwino kwambiri komanso mphamvu zamakina pa kutentha kwakukulu;
2) High resistivity ndi otsika kutentha coefficient kukana;
3) Reelability bwino ndi kupanga ntchito;
4) Kuchita bwino kwambiri kwa kuwotcherera
