Peb Tsev Neeg Khoom, Ib Lub Npe Tsis Txaus Siab
Kev yuav cov kev sib tham feem ntau sib xyaw tooj liab, tooj dag thiab tooj liab, thiab qhov tsis meej pem yog kim. Ib feem kev kos duab uas hu rau tooj liab yuav txaus siab zoo kawg nkaus los ntawm tooj dag, lossis nws yuav ua tsis tiav hauv kev pabcuam yog tias tooj dag raug hloov rau tooj liab ntawm qhov yuav tsum tau ua. Peb tsev neeg yog txhais los ntawm dab tsi yog alloyed nrog tooj liab.
Liab toojyog tooj liab unalloyed, feem ntau 99.9 feem pua tooj liab los yog siab dua. Nws muaj qhov zoo tshaj plaws hluav taws xob thiab thermal conductivity thiab qhov zoo tshaj plaws ductility, tab sis lub zog qis tshaj.
tooj dagyog tooj liab-zinc alloy. Zinc txhawb zog thiab hardness thaum txo cov conductivity thiab ductility.
Bronzeyog tooj liab alloyed feem ntau nrog tin, los yog nrog txhuas nyob rau hauv cov ntaub ntawv ntawm txhuas bronze, thiab muaj superior corrosion thiab hnav tsis kam ntawm tus nqi siab dua.
Liab tooj liab: siab tshaj conductivity, qis zog
Liab tooj liab, tseem hu ua tooj liab ntshiab, muaj ntau dua 99.9 feem pua tooj liab. Nws lub ntsej muag -cented cubic qauv muab nws zoo heev ductility thiab zoo heev hluav taws xob thiab thermal conductivity, thiab tus qauv qib T1 thiab T2 daim ntawv qhia nyob ze rau UNS C11000 nyob rau hauv American xyaum. Kev lag luam tawm -tawm yog txhua yam: tensile lub zog yog nyob rau ntawm qhov kev txiav txim ntawm 200 MPa nyob rau hauv annealed mob, yog li ib tug threaded fastener nyob rau hauv liab tooj liab yuav strip ntev ua ntej nws mus txog lub tsim load. Yog li ntawd, liab tooj liab tau teev tseg qhov twg conductivity yog txoj cai tswj hwm, xws li busbar, cable conductor, hluav taws xob switchgear kev twb kev txuas ntawm tus ntoo khaub lig loj -section thiab tshav kub exchanger tubing, thiab nws yog tsis tshua muaj cov lus teb rau cov qauv fastener.
Brass: Zinc Cov ntsiab lus tsav txhua yam
Brass yog tooj liab-zinc alloy tsev neeg thiab lub tsev ntuj tsim ntawm tooj dag fasteners thiab fittings. Nce zinc nce lub zog thiab hardness thiab txo ductility thiab conductivity. Tshaj li ntawm 45 feem pua zinc cov hlau ua nkig thiab nyuaj rau txheej txheem, uas yog vim li cas feem ntau cov qib tooj dag ua lag luam khaws zinc hauv qab li 40 feem pua. H series npe nyob rau hauv GB / T 5231 qhia cov ntsiab lus tooj liab nominal, yog li tus lej H qis dua txhais tau tias zinc ntau dua, muaj zog dua thiab qis dua.
| Qib | Cov ntsiab lus tooj liab,% | Cim | Hom kev siv |
|---|---|---|---|
| H59 | 57.0 rau 60.0 | Lub zog siab tshaj plaws thiab hardness ntawm cov tooj dag zoo tib yam, tus nqi qis tshaj, tsis muaj zog dezincification tsis kam | Tus nqi - kho vajtse rhiab heev, txiv ntseej, ntxhua khaub ncaws, brackets, qhuav- pabcuam fasteners |
| H62 | 60.5 rau 63.5 | Qhov zoo tshaj plaws txhua yam - puag ncig qhov sib npaug ntawm lub zog, ductility, machinability thiab nqi | Cov kav dej fittings, li qub, connectors, stamped thiab kos qhov chaw, terminals |
| H65 | 63.5 rau 68.0 | Ntau dua tooj liab, zoo dua txias formability thiab corrosion kuj, qis zog dua H62 | Sib sib zog nqus- kos qhov chaw, radiator cores, hniav trim, raj thiab sawb rau kev tsim |
H62 yog qib workhorse thiab yuav tsum yog qhov kev xaiv ua ntej tshwj tsis yog ib qho kev xav tau tshwj xeeb thawb kev xaiv rau H59 rau tus nqi thiab lub zog, lossis ntawm H65 rau kev tsim thiab corrosion lub neej.
Bronze: Tin thiab Aluminium Alloying rau Kev Pabcuam tawv
Bronze npog tooj liab alloys uas tin, aluminium, silicon los yog beryllium yog qhov tseem ceeb alloying ntxiv. Tin bronzes thiab phosphor bronzes muab kev tiv thaiv zoo rau cov dej hiav txwv, chav dej thiab dilute acids dua li cov tooj dag zoo tib yam, nrog rau kev hnav zoo thiab muaj txiaj ntsig zoo. Lub luag haujlwm tseem ceeb suav nrog marine hardware, twj tso kua mis thiab valve Cheebtsam, worm gears, lub tes tsho bearings, caij nplooj ntoos hlav tiv tauj thiab tshuaj cog fittings. Aluminium bronzes ntxiv lub zog siab thiab zoo heev tiv thaiv dej hiav txwv thiab rau ntau cov txheej txheem tshuaj, thiab feem ntau xaiv rau lub cev valve, twj impellers thiab hnav rings. Tus nqi ntawm qhov kev ua tau zoo no yog tus nqi ntawm cov khoom siv ntau dua thiab, hauv ntau qib, kev ua haujlwm nyuaj dua.
Ua hauv Brass thiab Export Market
Dawb- txiav brasses muaj cov khoom siv lead ua ntxiv, nyob rau hauv thaj tsam ntawm kwv yees li ib mus rau peb feem pua, uas txhim kho kev ua haujlwm tau zoo kom cov ntsia hlau taub hau ua kom huv si thiab cov xov txiav kom nrawm. Cov qhabnias tsis pub dawb - txiav cov qhab nia tseem yog txoj hauv kev ceev tshaj plaws thiab pheej yig tshaj plaws los tsim cov qib siab - ntim tau hloov pauv los ntawm tsev neeg tooj liab alloy. Txawm li cas los xij, txhuas yog cov khoom txwv tsis pub muaj nyob hauv ntau lub khw muag khoom, thiab rau cov dej haus sib cuag thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kev lag luam tau hloov mus rau cov hlau lead - pub dawb - txiav tooj dag uas hloov cov hmoov txhuas nrog bismuth los yog silicon thaum khaws cov khoom siv hluav taws xob ze rau cov qib coj. Rau ib qho kev pab cuam xa tawm, txoj cai qhov chaw, tsis yog kev cob qhia tus cwj pwm, yuav tsum txiav txim siab seb puas muaj qib coj los tso cai.
Kev taw qhia kev xaiv thiab tshuaj ntsuam xyuas
Conductivity yog qhov yuav tsum tau ua:siv tooj liab liab nyob rau hauv ib qho kev npau taws uas tsim nyog, los yog qis heev -zinc tooj dag yog tias lub zog me me ua rau pom tseeb qhov kev poob qis.
Lub zog thiab tus nqi dominate thiab ib puag ncig yog qhuav:H59 yog cov lus teb nyiaj txiag.
Forming, machining, dav fittings:H62 yog lub neej ntawd.
Sib sib zog nqus nqus thiab zoo dav corrosion lub neej: H65.
Dej hiav txwv, chav dej, hnav lossis coj lub luag haujlwm:tin, phosphor lossis aluminium bronze, tsis yog tooj dag zoo tib yam.
Fasteners rau potable dej tiv tauj:paub meej tias qhov txwv tsis pub coj mus muag ntawm lub khw muag khoom ua ntej xaj kom tsis pub dawb - txiav qib.
FAQ
Q: Puas yog tooj dag tib yam li tooj liab?
Tsis yog. tooj liab yog qhov tseem ceeb tsis muaj kev sib xyaw, ntawm 99.9 feem pua purity lossis siab dua, thaum tooj dag yog tooj liab -zinc alloy. Cov tooj dag muaj zog thiab pheej yig dua, tooj liab ua tau zoo dua thiab muaj ntau dua.
Q: Qhov txawv ntawm tooj dag thiab tooj dag yog dab tsi?
Brass yog alloyed nrog zinc, bronze principally nrog tin los yog aluminium. Bronze ib txwm muab zoo dua corrosion thiab hnav tsis kam thiab nqi ntau dua.
Q: Cov qib tooj dag twg yuav tsum yog qhov kev xaiv ua ntej?
H62. Nws muaj qhov zoo tshaj plaws sib npaug ntawm lub zog, ductility, machinability thiab nqi, thiab nws npog feem ntau ntawm fittings, connectors thiab tsim qhov chaw.
Q: Thaum twg H65 nyiam tshaj H62?
Thaum txias formability thiab corrosion lub neej tseem ceeb tshaj lub zog, piv txwv li nyob rau hauv sib sib zog nqus- kos qhov chaw, radiator Cheebtsam thiab hniav trim.
Q: Vim li cas cov hlau lead ntxiv rau qee cov tooj dag?
Txhawm rau txhim kho machinability thiab nti tsim kom siab - ntim cov khoom tuaj yeem tsim tau sai nrog qhov ua tiav zoo. Cov ntsiab lus txhuas yog txwv nyob rau hauv ntau lub khw muag khoom, yog li cov lead- yuav tsum muaj lwm yam dawb.
Q: Cov tooj dag puas tuaj yeem hloov tau rau bronze hauv marine kev pabcuam?
Tsis muaj kev nyab xeeb. Ordinary brasses yog qhov yooj yim rau dezincification thiab ua rau muaj kev ntxhov siab corrosion nyob rau hauv ib puag ncig chloride, yog li cov khoom siv hauv hiav txwv yuav tsum siv cov tooj liab lossis lwm cov hlau uas tsim los rau dej hiav txwv dej.
