CuNi44 Flat Waya (ASTM C71500/DIN CuNi44) Alloy-Copper Alloy don Abubuwan Lantarki
Bayanin samfur
CuNi44 Flat Waya
Fa'idodin Samfur da Bambance-bambancen Matsayi
CuNi44 lebur waya ta yi fice don ingantaccen juriyar wutar lantarki da ƙarfin aikin injin, yana mai da shi babban zaɓi don daidaitattun abubuwan lantarki. Idan aka kwatanta da irin irin abubuwan jan karfe-nickel irin su CuNi10 (Constantan) da CuNi30, CuNi44 yana ba da tsayayyar juriya mafi girma (49 μΩ · cm vs. 45 μΩ · cm don CuNi30) da ƙarancin zafin jiki na juriya (TCR), yana tabbatar da juriya kaɗan a cikin yanayin canjin yanayin zafi. Ba kamar CuNi10 ba, wanda ya yi fice a aikace-aikacen thermocouple, daidaitaccen daidaitawar CuNi44 na tsari da kwanciyar hankali na juriya ya sa ya dace don madaidaicin juriya, ma'auni, da shunts na yanzu. Ƙirar sashe mai lebur ɗin sa yana ƙara haɓaka ɓarkewar zafi da daidaituwar tuntuɓar juna idan aka kwatanta da wayoyi masu zagaye, yana rage zafi a cikin manyan aikace-aikacen yanzu.
