Aluminium yog qhov siv tshuaj. Nws lub cim tshuaj yog Al thiab nws cov atomic tooj yog 13. Cov ntsiab lus ntawm txhuas hauv lub ntiaj teb ua kaub puab yog thib ob rau oxygen thiab silicon, qeb thib peb, thiab yog qhov tseem ceeb tshaj plaws rau cov hlau hauv lub ntiaj teb ua kaub puab. Ntawm cov hom hlau, nws yog qhov thib ob loj tshaj hlau tom qab hlau. Nws tsis yog txog rau thaum xaus ntawm lub xyoo pua puv 19 tias txhuas tshwm sim, dhau los ua kev sib tw hlau hauv kev siv engineering, thiab nws tag nrho cov kev npau taws heev. Kev tsim kho ntawm peb qhov kev lag luam loj ntawm aeronautics, kev tsim kho, thiab cov tsheb yuav tsum tau hais tias cov khoom muaj cov khoom tshwj xeeb ntawm cov txhuas thiab nws cov khoom siv alloys, uas tau txais txiaj ntsig zoo ntau lawm thiab siv cov hlau tshiab no, txhuas. Daim ntawv thov ntawm txhuas yog dav heev.
Txhuas ntshiab txhuas yog qhov muag heev, tsis muaj zog, thiab muaj cov ductility zoo. Nws tuaj yeem raug kos rau hauv cov yeeb yaj kiab thiab dov mus rau hauv ntawv ci. Nws yog dav siv hauv kev tsim cov xov hlau, kab hlau, xov tooj cua kev lag luam thiab kev lag luam ntim. Nws cov hluav taws xob conductivity yog li ob feem peb ntawm tooj liab, tab sis txij li nws cov ntom ntuag tsuas yog ib feem peb ntawm tooj liab, piv rau cov xov hlau txhuas ntawm qhov sib luag ntawm qhov loj thiab qhov ntev, tooj liab muaj cov hluav taws xob hluav taws xob txog tooj liab. Nws yog ob zaug thiab ntau dua thiab tus nqi tsawg dua li tooj.
