Aluminium yog ib lub teeb hlau, thiab nws cov tebchaw yog dav faib nyob rau hauv cov xwm. Cov ntsiab lus ntawm txhuas nyob rau hauv lub crust yog hais txog 8 feem pua (qhov hnyav), qeb thib peb tsuas yog tom qab oxygen thiab silicon. Ntawm cov hom hlau, nws yog qhov thib ob loj tshaj plaws ntawm cov hlau, thib ob tsuas yog hlau. Aluminium muaj qhov zoo conductivity thiab ductility, thiab muaj ntau yam kev siv, nrog rau kev lag luam xws li lub teeb kev lag luam, lub zog, hluav taws xob, electronics, tsheb, mechanical manufacturing, tsim, ntim, thiab lwm yam. Nws yog ib qho tseem ceeb raw khoom rau kev loj hlob ntawm lub teb chaws kev khwv nyiaj txiag.
Lub ntsiab tseem ceeb cuam tshuam rau kev hloov pauv ntawm cov nqi txhuas yog:
(1) Ntau lawm thiab import thiab export ntim;
(2) Cov khoom ntim khoom;
(3) Qib ntawm cov nqi hluav taws xob;
(4) Qib ntawm kev siv cov khoom lag luam muaj feem cuam tshuam;
(5) Kev txhim kho thiab kev tsim kho tshiab ntawm cov txheej txheem ntau lawm.
Cov yam ntxwv tseem ceeb tsim nyog rau kev lag luam yav tom ntej:
A. Loj ntau lawm thiab muag ntim, nrog ntau tus neeg yuav khoom thiab muag khoom;
B. Uniform zoo, tej yam yooj yim specifications, thiab yooj yim faib ntawm cov qauv qib;
C. Yooj yim rau khaws thiab thauj;
D. Ntau zaus ntawm tus nqi hloov pauv
