Hluav taws xob resistivity yog ib qho peev xwm ntawm cov khoom siv los tawm tsam qhov ntws ntawm hluav taws xob tam sim no, pib los ntawm kev hloov hluav taws xob rau hauv tshav kub.
Cov khoom siv hluav taws xob (cov khoom siv hluav taws xob tiv thaiv hluav taws xob) yog siv, thiab lwm yam los txo cov dej ntws tam sim no, faib cov hluav taws xob, kho cov teeb liab theem, raws li kev ntsuas cov khoom siv hluav taws xob thiab tsim cov cua sov. High resistivity yog thawj cov cuab yeej tseem ceeb ntawm resistor alloys.
Resistivity thiab cua sov yog zoo sib xws. Ntxiv nrog rau qhov tseeb hais tias cov ntsiab lus resistive hloov hluav taws xob rau hauv tshav kub, thaum kub nce, qhov resistivity ntawm cov hlau feem ntau nce ntxiv.
Qhov no tshwm sim yog siv nyob rau hauv ntau txoj kev. Xav paub ntau ntxiv txog cov ntsiab lus ntawd hauv "Application" tab.
Lub resistivity ntawm cov ntaub ntawv resistor hloov me ntsis nrog qhov nce ntawm qhov kub thiab txias. Yog li ntawd, cov cuab yeej tseem ceeb thib ob ntawm resistor alloys yog qhov kub thiab txias coefficient ntawm resistivity.
Kub kub ceev oxidation. Yog li ntawd, cov cuab yeej tseem ceeb thib peb ntawm resistor alloys yog siab kub ua hauj.
Hluav taws xob tsis kam alloys yuav tsum tau ua kom tau raws li ntau lwm cov kev cai kom thiaj li muaj txiaj ntsig. Resistor alloys kuj tau piav qhia los ntawm lwm yam khoom, xws li:
Tam sim no muaj peev xwm
Lub zog tensile
Melting kub
Ua haujlwm kub siab tshaj plaws
Yield point
Ua haujlwm tau
Kev cuam tshuam rau recrystallization
Corrosion kuj
Kev txhaj tshuaj muaj peev xwm
