Tooj liab yog ib qho ntawm thawj cov hlau pom los ntawm tib neeg, thiab ib qho ntawm cov hlau ntshiab zoo dua.Nws muaj cov yam ntxwv nram qab no: me ntsis tawv, tawv heev, hnav-resistant, zoo ductility, zoo thermal thiab hluav taws xob conductivity, tib lub sij hawm, cov tooj liab alloy muaj zoo corrosion kuj, yog ruaj khov nyob rau hauv qhuav huab cua, ruaj thiab regenerated.Yog li ntawd, cov khoom zoo tshaj plaws ntawm tooj liab thiab tooj liab alloy ua cov ntaub ntawv tau raug soj ntsuam zoo hauv cov khoom siv hluav taws xob, kev tsim khoom, kev sib txuas lus, tsheb, kev ntsuas, thiab kev lag luam tub rog.
