Taw qhia rau Copper Alloys

Brass yog tooj liab alloy nrog zinc ua lub ntsiab additive. Nws muaj cov xim daj zoo nkauj thiab tau sau npe hu ua tooj dag. Copper-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 nrog zinc cov ntsiab lus tsawg dua 36% yog tsim los ntawm cov khoom siv tshuaj thiab muaj cov khoom ua haujlwm txias. Piv txwv li, tooj dag nrog zinc cov ntsiab lus ntawm 30% feem ntau yog siv los ua cov mos txwv, feem ntau hu ua mos txwv 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 daws teeb meem thiab feem ntau siv yog rau-plaub tooj dag nrog 40% zinc. Txhawm rau txhim kho kev ua tau zoo ntawm cov tooj dag zoo tib yam, lwm yam khoom xws li txhuas, npib tsib xee, manganese, tin, silicon, txhuas, thiab lwm yam. Aluminium tuaj yeem ua kom lub zog, hardness thiab corrosion kuj ntawm tooj dag, tab sis txo nws cov plasticity. Nws yog tsim rau marine condensers thiab lwm yam corrosion-resistant qhov chaw. Tin tuaj yeem txhim kho lub zog ntawm tooj dag thiab nws cov kev tiv thaiv corrosion rau seawater, yog li nws yog hu ua naval tooj dag thiab siv rau cov khoom siv hauv nkoj thermal thiab cov kiv cua. Cov hmoov txhuas tuaj yeem txhim kho kev ua haujlwm ntawm cov tooj dag; hom dawb-txiav tooj dag no feem ntau yog siv los ua ib feem ntawm lub moos thiab watches. Brass castings feem ntau yog siv los ua cov li qub thiab cov yeeb nkab fittings. Cov khoom tawg-pov thawj crescent wrench rau cov hluav taws kub hydrants feem ntau siv hauv nkoj yog ua los ntawm tooj dag thiab txhuas.
