Corrosion Resistance ntawm tooj dag
Brasses yog resistant rau corrosion nyob rau hauv ntau yam xov xwm. Thov sab laj Austral Wright Metals rau cov lus qhia ntxaws ntxaws ntawm koj daim ntawv thov. Brasses tshwj xeeb tshaj yog raug rau corrosion los ntawm kev daws teeb meem uas muaj ammonia lossis amines. Alloys nrog ntau tshaj li ntawm 15% ntawm zinc yuav raug kev txom nyem dezincification, uas tawm ib tug qaug zog, ntxeem tau corrosion deposit ntawm tooj liab. Kev tiv thaiv rau dezincification yog txo qis heev los ntawm kev ntxiv me me ntawm arsenic rau cov hlau. Kev ntxhov siab corrosion cracking, tshwj xeeb tshaj yog los ntawm ammonia thiab amines, kuj yog ib qho teeb meem nrog cov tooj dag. Alloys uas muaj ntau tshaj li ntawm 15% zinc yog feem ntau raug. Kev siv cov annealed temper, thiab annealing los yog kev nyuaj siab relieving tom qab tsim, thiaj li susceptibility to stress corrosion cracking.
Gilding Hlau Copper Alloy - Cov khoom thiab kev siv
Cov Dab Neeg
Kuj hu ua liab tooj dag, lag luam bronze, gilding hlau. C22000 muab cov xim zoo nkauj zoo nkauj nrog kev sib xyaw zoo tshaj plaws ntawm lub zog, ductility thiab corrosion kuj ntawm cov tooj liab-zinc alloys. Nws huab cua mus rau cov xim bronze nplua nuj, thiab tuaj yeem muab rau hauv cov xim pre-patinated xws li xim av sib sib zog nqus mus rau ntsuab. Nws muaj qhov qis dua ntawm kev ua haujlwm hardening dua li cov tooj liab-zinc alloys nrog zinc cov ntsiab lus siab dua, xws li 260 thiab 272. Qhov no yog qhov zoo dua hauv kev siv ntau theem nias yam tsis muaj kev cuam tshuam kev cuam tshuam. Nws muaj cov yam ntxwv sib sib zog nqus zoo heev thiab ua haujlwm rau pitting corrosion thiab kev ntxhov siab corrosion tawg thaum raug huab cua hnyav thiab dej ib puag ncig.
Corrosion Resistance ntawm Gilding Hlau Copper Alloy
Raws li alpha tooj dag nrog cov ntsiab lus zinc tsawg, C22000 muaj corrosion zoo heev nyob rau hauv feem ntau cov xov xwm. Nws tsis tshua muaj kev cuam tshuam rau kev ntxhov siab corrosion ntau dua li zinc brasses siab dua xws li 70/30 tooj dag C26000, thiab tsis suav tias muaj kev cuam tshuam hauv cov huab cua hauv hiav txwv. Txawm li cas los xij, nws yuav tsum tsis txhob siv rau hauv kev sib cuag nrog aqueous ammonia thiab amines. C22000 yuav tsum tsis txhob siv nrog acetic acid, acetylene, brines, calcium chloride, moist chlorine, chromic acid, hydrochloric acid, mercury los yog nws cov tebchaw, nitric acid thiab sodium hypochlorite.
Brass thiab Arsenical Brass Alloy - Cov khoom thiab kev siv
Kuj tseem hu ua cartridge tooj dag, spinning tooj dag, caij nplooj ntoos hlav tooj dag. C26000, 70/30 Brass thiab C26130, Arsenical tooj dag, muaj ductility zoo heev thiab lub zog, thiab yog cov siv tooj dag tshaj plaws. Arsenical tooj dag muaj me me ntxiv ntawm arsenic, uas zoo heev txhim kho corrosion kuj nyob rau hauv dej, tab sis yog lwm yam zoo tib yam. Cov hlau no muaj cov xim daj daj tshwj xeeb uas feem ntau cuam tshuam nrog tooj dag. Lawv muaj qhov zoo tshaj plaws ua ke ntawm lub zog thiab ductility nyob rau hauv cov tooj liab-zinc alloys, ua ke nrog zoo corrosion kuj.
C26000 yog siv rau architecture, kos thiab spun ntim thiab cov duab, hluav taws xob terminals thiab connectors, qhov rooj tuav, kav dej kho vajtse. C26130 yog siv rau cov raj thiab fittings hauv kev sib cuag nrog dej, suav nrog cov dej haus.
Corrosion Resistance ntawm Brass thiab Arsenical Brass Alloy
C26000 muaj corrosion kuj zoo rau huab cua thiab zoo heev tiv thaiv ntau yam tshuaj. Nws tuaj yeem ua rau dezincification nyob rau hauv stagnation los yog maj mam txav ntsev tov, dej brackish los yog acidic daws. Txawm hais tias nws yuav tiv taus dej feem ntau, C26130 nyiam dua vim nws muaj cov arsenic me me ntxiv uas inhibits corrosion.
C26000 yuav tsum tsis txhob siv nyob rau hauv kev sib cuag nrog ammonia los yog ammonia tebchaw, raws li nws yuav raug kev nyuaj siab corrosion cracking. Ceev faj txog kev tiv thaiv corrosion hauv cov kav dej uas muaj cov pa roj carbon steel, uas yuav tsum tau kuaj xyuas kom haum rau cov alloy C26000. 70/30 tooj dag yuav tsum tsis txhob siv nrog acetic acid, acetylene, brines, calcium chloride, moist chlorine, chromic acid, hydrochloric acid, mercury los yog nws cov tebchaw, nitric acid thiab sodium hypochlorite.
