Tooj yog mos, tab sis nws yog tawv. Nws yog yooj yim tov nrog lwm cov hlau los tsim cov alloys xws li tooj liab thiab tooj liab. Bronze yog cov tin thiab tooj liab alloy, thiab tooj dag yog zinc thiab tooj liab alloy. Cov tooj liab thiab tooj dag yog siv tau sai. Tej zaum 70% ntawm cov tooj liab siv tau raug siv dua tsawg kawg ib zaug. Qhov ntom ntawm cov khoom siv tshuaj dawb huv ib txwm muaj npe raws li qhov sib npaug ntawm qhov sib npaug crystalline lub xeev ntawm cov khoom ntawd, feem ntau nyob rau hauv chav tsev kub tshwj tsis yog tias tau teev lwm yam. . Cov ntaub ntawv no yuav tsum tau muab rau hauv siab thaum xav txog qhov ntom ntom piv txwv, ntawm tooj liab uas muaj FCC siv lead ua qauv. Cov feem ntim rau FCC kaw-packed qauv ntawm cov spheres nyuaj yog 0.740. Qhov sib txawv me ntsis ntawm ob txoj kev suav [ntxiv cov feem yog vim truncation thiab rounding off.Qhov ceev ntawm tooj liab nyob rau hauv lub amphorous khoom lub xeev ntawm chav tsev kub yuav kwv yees los ntawm qhov ratio ntawm packing feem. Tooj liab yog qhov tshwm sim ntau tshaj plaws uas tsis yog kub nrog cov xim txawv. Tsis zoo li kub thiab nyiaj, tooj liab yog ib tug zoo kawg nkaus conductor ntawm tshav kub thiab hluav taws xob. Nws yog heev malleable thiab ductile, ib yam nkaus. Copper kuj yog corrosion-resistant (nws tsis xeb yooj yim heev).
