Feem ntau siv tooj liab thiab nws cov alloys yog:tooj liab ntshiab, tooj dag, bronze, thiab lwm yam. Cov tsos ntawm cov ntshiab tooj liab yog liab-daj.Nyob rau hauv cov huab cua, qhov saum npoo yuav tsim cov xim liab-liab ntom zaj duab xis vim oxidation, yog li nws tseem hu ua liab tooj liab.Cov hluav taws xob conductivity thiab thermal conductivity ntawm ntshiab tooj liab yog zoo heev, thib ob tsuas yog nyiaj.Nws kuj muaj tshuaj lom neeg ruaj khov thiab zoo corrosion kuj nyob rau hauv cov huab cua thiab dej tshiab.Feem ntau, nyob rau hauv ib qho chaw ntub dej, nws yooj yim los tsim cov tooj liab carbonate (feem ntau hu ua patina).Ntshiab tooj liab muaj plasticity zoo tab sis tsis tshua muaj zog txhua yam.Muaj cov tooj liab ntshiab feem ntau muaj qee yam ntawm cov pa oxygen, sulfur, lead, bismuth, arsenic thiab lwm yam impurity.Qhov me me ntawm arsenic tuaj yeem ua rau tooj liab lub zog, hardness, thiab txo cov hluav taws xob thiab thermal conductivity.Cov seem ntawm impurity ntsiab yog teeb meem.Cov tooj liab ntshiab yog siv los tsim cov xov hlau, cov khoom siv hluav taws xob thiab ntau yam khoom siv tooj liab hauv kev lag luam.Ntawm lawv, tooj liab dawb tsis muaj oxygen yog siv los ua hluav taws xob lub tshuab nqus tsev.
Brass yog ib qho alloy ntawm tooj liab thiab zinc.Thaum cov ntsiab lus zinc ntawm tooj dag qis dua 32, cov yas yog qhov zoo, haum rau kev ua haujlwm txias thiab kub, thiab tawv tawv yog muaj zog, tab sis kev ua haujlwm tsis zoo.Txhawm rau txhim kho qee yam khoom ntawm tooj dag, ib qho me me ntawm lwm cov ntsiab lus feem ntau yog ntxiv, xws li txhuas, manganese, tin, silicon, txhuas, thiab lwm yam. Cov tooj dag no hu ua tooj dag tshwj xeeb.Brass yog siv nyob rau hauv thermal fais fab nroj tsuag los ua cov cua kub pauv raj rau chav turbine condensers.Piv txwv li, N-11200-1 hom condenser tooj liab tube khoom siv nyob rau hauv lub domestic 200,000-kilowatt chav turbine yog: feem ntau 77-2 txhuas tooj dag nyob rau hauv lub ntshiab seawater cheeb tsam, thiab 70-1 tin tooj dag nyob rau hauv cov dej tshiab.
