Aluminium yog hlau ntshiab, thaum hlau yog ib qho kev sib xyaw (sib xyaw ntawm cov hlau thiab lwm yam). Ntawm no yog qhov tawg:
1. Txhuas kev faib tawm: ib qho tshuaj lom neeg (cim al, atomic tooj 13) ntawm lub rooj ntu, categorized ua cov hlau tom qab. Cov Khoom: Lub teeb yuag, silver-dawb, thiab mally mallyle. Cov neeg ua yeeb yam zoo tshaj plaws ntawm tshav kub thiab hluav taws xob. Ib txwm ua cov txheej txheem oxide txheej (tiv taus corrosion). Siv: Cov kaus poom haus dej, qhov chaw dav hlau, ntawv ci, thiab cov khoom siv.
2. Kev faib tawm hlau: ib qho alloy ua cov hlau (FE) thiab carbon (c), feem ntau nrog lwm cov yam xws li chromium lossis npib tsib xee. Cov khoom: muaj zog, nyuaj, thiab ruaj khov. Nquag mus xeb tshwj tsis yog kho lossis txuam nrog (piv txwv li, stainless hlau). Siv: Cov tuam tsev, cuab yeej, tsheb, thiab tshuab. Qhov sib txawv: Aluminium yog ib qho khoom (ib hom atom). Hlau yog tib neeg-ua alloy (hlau + roj carbon + Lwm yam). Muaj peev xwm txhuas yog ib feem ntawm cov hlau? Tsis tau. Steel-based, tab sis txhuas qee zaum sib xyaw nrog lwm cov hlau los tsim cov hlau alloys (piv txwv li, rau dav hlau). Cov no yog txawv ntawm steel.
