Raws li cov khoom siv ntau yam tshiab, tooj liab ua npuas ncauj feem ntau yog ua los ntawm tooj liab, thiab ntau qhov sib txuas lossis cov qhov tsis sib txuas tau muab faib ua tusyees, yog li tsim cov khoom siv ntau yam tshiab xws li tooj liab ua npuas ncauj.
Copper ua npuas ncauj yog soundproof thiab demagnetizing, tsis muaj tshuaj lom thiab tsis muaj teeb meem.

Feem ntau cov hlau ua npuas ncauj muaj lub suab rwb thaiv tsev zoo thiab tuaj yeem tiv thaiv electromagnetic signals. Copper ua npuas ncauj kuj muaj qhov zoo dua, yog vim li cas lub suab ntawm qhov chaw ntawm tooj liab ua npuas ncauj, tsis tsuas yog yuav tshwm sim diffuse reflection; kuj los ntawm kev nthuav dav ntawm lub suab dissipation. Qhov laj thawj micro-porous anechoic, tiag tiag ua tiav cov nyhuv ntawm lub suab anechoic. Nyob rau tib lub sijhawm, tooj liab ua npuas ncauj kuj tseem tuaj yeem tiv thaiv cov cim hluav taws xob, thiab feem ntau siv los ua cov khoom siv hluav taws xob tiv thaiv hluav taws xob. Tooj liab ua npuas ncauj nws tus kheej tsis muaj tshuaj lom thiab tsis muaj mob rau tib neeg lub cev, nrog ntau qhov pores sab hauv; nws kuj yog siv los ua cov khoom siv lim dej kho mob los ntawm ntau lub tuam txhab ua dej huv.
Copper ua npuas ncauj muaj cov khoom siv hluav taws xob zoo dua vim tias nws tsis tshua muaj nqi los tsim dua li nickel ua npuas ncauj; Yog li ntawd, nws yog dav siv los ua cov khoom siv electrode hauv cov roj teeb tshiab. Copper ua npuas ncauj kuj tseem siv los ua ib qho catalyst los pab txhawb cov tshuaj lom neeg hauv qee cov tshuaj lom neeg cov tshuaj lom neeg vim nws qhov loj ntawm thaj chaw tshwj xeeb. Meanwhile, tooj liab ua npuas ncauj muaj zog thermal conductivity thiab zoo heev nplaim retardancy; Nws yog feem ntau siv rau hauv kev tsim cov khoom siv thermally thiab yog dav siv nyob rau hauv hluav taws xob motors thiab hluav taws xob kub dissipation cov ntaub ntawv.
