CuNi44 Constantan Resistance Alloy Wire rau Precision Resistors & Thermocouples

Khoom piav qhia:

CuNi44 alloy (tseem hu ua Constantan, Alloy 300, Cuprothal 294, Cupron) yog ib qho tooj liab-nickel tsis kam alloy nrog 44% nickel cov ntsiab lus. Nws muaj qhov kub tsis tshua muaj coefficient ntawm kev tsis kam (TCR), ua rau nws zoo tagnrho rau cov precision resistors, shunts, thermocouple extension wires, thiab cov ntawv thov cua sov qis.

Peb cov hlau CuNi44 muaj kev sib xws zoo heev, weldability zoo, thiab ruaj khov mus sij hawm ntev. Nws yog dav siv rau hauv cov cuab yeej hluav taws xob, cov sensors tsheb, cov tshuab tswj hwm aerospace, thiab cov khoom siv hauv chaw kuaj mob.

Peb tuaj yeem muab cov hlau puag ncig, hlau tiaj tus, thiab ribbon / strip hauv ntau txoj kab uas hla thiab kev kam rau ua
