Lub zog yog ib txwm soj ntsuam los ntawmpaib lub zog(Kev nyuaj siab ntawm uas muaj kev cuam tshuam mus tas li) thiabLub zog tensile(kev ntxhov siab tshaj plaws ua ntej tawg). Ntawm no yog li cas tus qauv tooj liab-}}}}}} ecoil alloys sib piv cov hom steel:

Tooj liab -} nickel txoj kev loj tshaj plaws "lub zog" hauv ntau qhov kev lag luam tsis yog nws cov khoom siv zog, tab sis nwsCorrosion Kuj Tsis TxausCov. Hlau (txawm tias stainless hlau) corrownes sai sai hauv dej hiav txwv, cov tshuaj tawg, lossis cov khoom siv ua kom pom tseeb (piv txwv li cov xim pleev xim rau, galvanization) lossis yooj yim hloov.

Piv txwv li:
