High purity tooj liab yog mos, malleable, ductile hlau nrog siab thermal thiab hluav taws xob conductivity. Qhov saum npoo ntawm freshly nthuav tawm ntshiab tooj liab yog reddish txiv kab ntxwv. Copper yog siv los ua cov khoom siv hluav taws xob thiab hluav taws xob, ua cov khoom siv hauv tsev, thiab ua ib feem ntawm ntau yam hlau alloys, xws li nyiaj sterling nyiaj rau cov hniav nyiaj hniav kub, tooj liab-nickel rau kev tsim khoom ntawm Marine hardware thiab npib, thiab Constantine rau strain gauges thiab thermocouples los ntsuas qhov kub thiab txias. Qhov kawg lub zog ntawm siab purity tooj liab yog hais txog 210 MPa thiab lub zog tawm los yog li 33 MPa, uas txwv nws muaj nyob rau hauv cov ntawv thov kev lag luam. Tab sis zoo li lwm yam alloys, tooj liab tuaj yeem ntxiv dag zog. Lub zog mechanism ntawm tooj liab puag alloy yog tsuas yog alloying. Copper alloy yog raws li tooj liab alloy, lub ntsiab alloy ntsiab yog Zn, Sn, Si, Al, Ni. Copper raws li alloys yog tsim los ntawm cov kuab tshuaj los yog impurity atoms hloov los yog hloov matrix atoms hloov cov kev daws teeb meem.
