Yog lawm, Al) (AL) yog 100% hlau nyob rau hauv nws cov ntawv ntshiab. Ntawm no yog vim li cas:
1. Kev faib tawm ntawm kev sib koom ua ke ntawm cov khoom lag luam aluminium yog ib qho khoom ntawm lub rooj ntu (atomic lej 13). Nws zwm rau pab pawg 13 (tom qab kev hloov pauv ntawm cov hlau), ib qeb ntawm cov ntsiab lus nrog cov khoom siv hlau uas zoo li nws nyiam, malleability, thiab luster.
2. Lub cev cov cwj pwm: hluav taws xob siab thiab thermal conductivity. Malleable (tuaj yeem dov mus rau hauv ntawv ci) thiab dutras (kos rau hauv xaim). Ci iab, silvery tsos (xim hlau lug). Kev coj cwj pwm: kev tawm tsam nrog oxygen los ua ib txheej tiv thaiv oxide txheej (al₂o₃). Poob cov tshuab hluav taws xob los ua kom zoo ions (al³n), ib qho taw qhia ntawm cov hlau.
3. Cov kev txiav txim siab ua tau ntshiab Txhuas: Hauv nws daim ntawv purest (99.9% +), txhuas yog xim hlau nkaus xwb. Txawm li cas los xij, nws yog mos thiab tsis tshua siv siv kev lag luam. Alloys: feem ntau cov khoom "txhuas" (piv txwv li, cov kaus poom, cov khoom siv dav hlau) yog cov hlau nplaum me me) los txhim kho lub zog. Cov alloys khaws cov khoom siv hlau me me. Cov tebchaw: Txhuas Cov Ntawv Tsis yog-hlauic cov tebchaw (piv txwv, aluminium oxide, al₂o₃), tab sis cov no yog txawv ntawm cov hlau ntshiab. Kev ua kom tsis meej "Txhuas tsis yog xim hlau": qhov xwm txheej tsis meej pem lossis cov txheej txheem oxide uas tsis zoo siab, tab sis cov cwj pwm tsis txwv nws yog nws cov hlau me me. "Txhuas Ntawv ci tsis yog Ntshiab": Tsev neeg ntawv ci yog ze li Aluminium txhuas ({}}%), nrog kab kawm rau lub sijhawm ntev.
Xaus: Ua ib qho khoom noj, txhuas yog 100% hlau. Thaum nws alloys thiab tebchaw thiab cov tebchaw yuav suav nrog cov khoom siv tsis yog txhuas cov khoom siv, cov khoom siv hauv paus nws tus kheej yog nws tus kheej nkaus xwb.
