tooj dag yog tooj liab alloy nrog zinc raws li lub ntsiab additives, uas muaj ib tug zoo nkauj daj xim thiab yog collectively hu ua tooj dag.Cov tooj liab-zinc binary alloy yog hu ua tooj dag lossis tooj dag yooj yim.Brass nrog ntau tshaj peb yuan yog hu ua tooj dag tshwj xeeb lossis tooj dag complex.Brass alloys uas muaj tsawg dua 36% zinc yog tsim los ntawm cov khoom siv tshuaj thiab muaj cov khoom ua haujlwm txias.Piv txwv li, tooj dag uas muaj 30% zinc feem ntau yog siv los ua cov mos txwv, feem ntau hu ua mos txwv casing tooj dag lossis xya-peb tooj dag.Brass alloys nrog zinc cov ntsiab lus ntawm 36 thiab 42% yog tsim los ntawm cov khoom siv tshuaj, uas feem ntau siv yog rau-plaub tooj dag nrog zinc cov ntsiab lus ntawm 40%.Txhawm rau txhim kho cov khoom ntawm cov tooj dag zoo tib yam, lwm cov ntsiab lus feem ntau ntxiv, xws li txhuas, npib tsib xee, manganese, tin, silicon, txhuas, thiab lwm yam. Txhuas tuaj yeem txhim kho lub zog, hardness thiab corrosion kuj ntawm tooj dag, tab sis txo cov plasticity, yog li nws yog tsim rau seagoing condenser kav thiab lwm yam corrosion-resistant qhov chaw.Tin tuaj yeem txhim kho lub zog ntawm tooj dag thiab kev tiv thaiv corrosion rau cov dej hiav txwv, yog li nws yog hu ua naval tooj dag thiab siv rau cov khoom siv hauv nkoj thermal thiab cov kiv cua.Lead txhim kho lub machinability ntawm tooj dag;no dawb-txiav tooj dag yog feem ntau siv nyob rau hauv saib qhov chaw.Brass castings feem ntau yog siv los ua cov li qub thiab cov yeeb nkab fittings, thiab lwm yam.

Bronze Ameslikas hais txog tooj liab-tin alloys, thiab tom qab ntawd tooj liab alloys uas tsis yog tooj dag thiab cupronickel hu ua bronzes, thiab feem ntau muab lub npe ntawm thawj lub ntsiab ntxiv ua ntej lub npe ntawm tooj liab.Tin bronze muaj cov khoom zoo casting, tiv thaiv kev sib txhuam thiab cov khoom siv zoo, thiab tsim nyog rau kev tsim cov bearings, worm gears, gears, thiab lwm yam. Lead bronze yog cov khoom siv dav siv rau cov cav tov niaj hnub thiab grinders.Aluminium bronze muaj lub zog siab, zoo hnav tsis kam thiab corrosion kuj, thiab yog siv rau casting high-load gears, bushings, marine propellers, thiab lwm yam. Beryllium bronze thiab phosphor bronze muaj siab elastic txwv thiab zoo hluav taws xob conductivity, thiab yog haum rau manufacturing precision. springs thiab hluav taws xob tiv tauj cov ntsiab lus.Beryllium bronze kuj tseem siv los ua cov cuab yeej tsis muaj teeb meem siv hauv cov mines thiab roj depots.
