Thaum sib piv cov hluav taws xob conductivity ntawm txhuas thiab tooj liab, ob peb yam yuav tsum tau xav txog, suav nrog lawv cov khoom siv hluav taws xob sab hauv, hnyav, nqi, thiab tej kev siv. Ntawm no yog cov ncauj lus kom ntxaws sib piv:

Hluav taws xob conductivity

• Tooj: Tooj muaj ib tug hluav taws xob conductivity 5.96 × 10⁷$\text{S/m}$ (siemens ib 'meter'). Nws yog tus qauv uas lwm yam conductors raug ntsuas thiab muab ib tug conductivity ntawm 100% International Annealed Copper Standard (IACS).
• Aluminium: Aluminium muaj hluav taws xob conductivity ntawm 3.77 × 10⁷$\text{S/m}$, uas yog kwv yees li 63% uas yog tooj liab IACS.

Qhov hnyav thiab ntom

• Tooj: Cov qhov ntom ntawm tooj liab yog hais txog 8.96 g/cm³. Qhov no ua rau tooj liab kuj hnyav piv rau aluminium.
• Aluminium: Cov density ntawm aluminium nyob ib ncig ntawm 2.7 g/cm³. Aluminium yog ntau sib dua, txog ib feem peb qhov hnyav ntawm tooj liab.

Lub zog thiab cov cuab yeej cuab tam

• Tooj: Copper muaj zog dua thiab ruaj khov dua nyob rau hauv kev ntxhov siab thiab tuaj yeem tiv taus ntau dua yam tsis muaj deformation.
• Aluminium: Aluminium yog ntau malleable thiab tsis tshua muaj kev tawg tab sis muaj zog tensile qis dua piv rau tooj liab.

Nqi

• Tooj: Feem ntau, tooj liab yog kim dua vim nws qhov kev thov siab dua thiab cov khoom siv hluav taws xob zoo dua.
• Aluminium: Aluminium tsis tshua kim thiab ntau dua, ua nws tus nqi-zoo lwm txoj hauv ntau daim ntawv thov.

Daim ntawv thov

• Tooj: Siv dav hauv kev xaim hluav taws xob, lub cev muaj zog, transformers, thiab lub zog tsim hluav taws xob vim nws zoo heev conductivity thiab durability.
• Aluminium: Feem ntau siv rau hauv kev xa hluav taws xob thiab cov kab xa tawm, qhov twg nws qhov hnyav dua tuaj yeem txo cov nqi txhawb nqa.

Kev xav txog tswv yim

• Qhov loj thiab qhov hnyav rau qhov sib npaug sib npaug: Yuav kom ua tiav cov hluav taws xob conductivity tib yam li tooj liab, aluminium conductor yuav tsum muaj thaj tsam loj dua. Txawm li cas los, txawm nrog qhov loj dua, tag nrho qhov hnyav ntawm aluminium conductors tseem qis dua li ntawm tooj liab conductors.
• Corrosion Resistance: Aluminium tsim ib txheej tiv thaiv oxide uas ua rau nws tiv taus corrosion. Tooj liab tuaj yeem corrode, tshwj xeeb tshaj yog nyob rau hauv tej qhov chaw, tab sis qhov no feem ntau yog tswj hwm nrog cov txheej txheem tsim nyog thiab kev kho mob.
• Kev Sib Txuas Kev Ntseeg: Aluminium requires careful handling to ensure secure connections, raws li nws tuaj yeem nthuav dav thiab cog lus ntau dua tooj liab nrog kev hloov pauv kub, muaj peev xwm ua rau muaj kev sib txuas xoob raws sijhawm. Cov txuas tshwj xeeb thiab cov txheej txheem kev teeb tsa tau siv los txo qhov no.
