Lead Brass yog dab tsi

Lead brasses yog siv rau lawv cov machinability siab thiab atmospheric corrosion kuj. lub machinability ntawm tooj dag yog nce los ntawm qhov sib ntxiv ntawm cov hlau lead vim nws ua raws li microscopic nti breaker thiab cov cuab yeej lubricant. cov hlau lead yog siv rau tooj liab puag ntsia hlau cov khoom siv. cov alloys muaj zoo heev machinability, zoo zog thiab corrosion kuj. txhuas tuaj yeem muab ntxiv rau txhua qhov tooj dag kom ua haujlwm tau zoo thiab muab lub zog nruj los ntawm kev sib khi lub qhov txhab shrinkage. muaj cov hmoov txhuas qis, nruab nrab thiab siab, nrog cov ntsiab lus txhuas mus txog 3.5%. cov hlau lead brasses yog siv rau architectural hardware, general hom phiaj ntsia hlau tshuab qhov chaw, screws, li qub, fittings, bearings thiab tshwj xeeb fasteners. Cov hlau lead wrought yog tsim los ntawm uns c31200 txog c38500. cam khwb cia hlau cam khwb cia hlau yog ua ke nrog lawv cov unleaded txee qhov chaw, thiab poob nyob rau hauv ntau yam ntawm alloys ntawm c83600 txog c97300.

Cov txiaj ntsig ntawm Lead Brass

01/

Yooj yim rau tshuab
Qhov ob hom tooj dag siv rau cov khoom siv yog 353 thiab 360 tooj dag. ob qho tib si ntawm cov alloys no yog kwv yees li 62% tooj liab, 35% zinc, 2-3% txhuas, thiab cov lej ntawm cov hlau.

02/

Resistant rau corrosion
Hlau yog cov khoom uas ua rau cov hlau feem ntau xeb thiab deteriorate. Tias yog vim li cas feem ntau hlau thiab dej tsis sib tov zoo. vim tooj dag muaj me me ntawm cov hlau, nws tsis raug rau xeb. nyob rau hauv txoj cai tej yam kev mob, tooj dag qhov chaw yuav siv tau rau ntau pua xyoo.

03/

High conductive
Lead tooj dag tsis yog conductive li tooj liab, tab sis nws tseem yog ib tug zoo conductor ntawm tshav kub thiab hluav taws xob. txhuas tooj dag kuj yog ib qho nyuaj thiab ruaj khov dua tooj liab, yog li nws tau siv rau hauv cov ntawv thov uas muaj kev sib txhuam ntau dua thiab siab.

04/

Lead Brass tuaj yeem tswj tau qhov kub thiab txias
Lwm qhov txiaj ntsig zoo ntawm cov hlau lead tooj dag yog tias nws tuaj yeem ua haujlwm kub siab heev yam tsis muaj kev poob haujlwm.Qhov no ua rau cov hlau lead tooj dag yog cov khoom siv zoo rau cov dej kub.cov tooj dag qhov chaw txuas ntxiv muab cov dej tsis zoo zoo txawm tias kub kub. qhov no ua rau kom qhov ua tau zoo ntawm qhov system thiab tiv thaiv cov dej xau.

Dab tsi yog Daim Ntawv Thov ntawm Lead Brass

Motor manufacturing

Nyob rau hauv kev tsim lub cev muaj zog, tooj liab alloys nrog siab conductivity thiab lub zog yog dav siv. Lub ntsiab Lead Brass qhov chaw yog stator, rotor, thiab ncej taub hau.

Kev sib txuas lus cables

Txij li thaum xyoo 1980s, vim qhov zoo ntawm qhov loj tam sim no-nqa lub peev xwm ntawm fiber ntau optical cables, lawv tau hloov pauv tsis tu ncua tooj liab cables ntawm kev sib txuas lus nraub qaum thiab txhawb kev thov sai. Txawm li cas los xij, qhov loj ntawm cov hlau lead tooj dag tseem xav tau los hloov hluav taws xob hluav taws xob rau hauv lub zog kho qhov muag thiab cov neeg siv cov kab nkag.

Kev lag luam hluav taws xob

Lead tooj dag yog siv los tsim lawv vim nws zoo thermal conductivity thiab tsis kam mus rau dej corrosion. lawv txhua tus yog ua los ntawm tooj dag daj, txhuas tooj dag lossis tooj liab dawb.

Cov ntawv luam tawm

Lead tooj dag luam tawm circuits siv tooj liab ntawv ci los ua ib qho chaw, uas yog muab tso rau ntawm lub rooj tsavxwm yas ua kev txhawb nqa. daim duab hluav taws xob thaiv hluav taws xob tau luam tawm ntawm lub phaj tooj liab los ntawm photolithography, thiab feem ntau yog tshem tawm los ntawm etching kom tawm hauv ib qho kev sib tshuam.

Hom Lead Brass

Manganese tooj dag
Manganese muaj ntau dua solubility hauv cov tooj dag. ntxiv 1% mus rau 4% manganese rau tooj dag zoo heev txhim kho lub zog thiab corrosion kuj ntawm cov hlau tsis txo nws cov plasticity. manganese tooj dag muaj (+ ) qauv, thiab hmn 58-2 feem ntau yog siv, nrog zoo txias thiab kub siab ua hauj lwm.

Hlau tooj
Nyob rau hauv cov hlau daj tooj liab, hlau precipitates li hlau-nplua nuj hais, uas yog siv lead ua nuclei los kho cov nplej thiab tiv thaiv recrystallized nplej los ntawm kev loj hlob, kev txhim kho cov neeg kho tshuab thiab technological zog ntawm cov alloy. cov ntsiab lus hlau hauv hlau tooj dag feem ntau yog tsawg dua 1.5%, thiab nws muaj cov qauv (+). nws muaj zog thiab toughness thiab zoo plasticity ntawm qhov kub thiab txias thiab tuaj yeem deformed ntawm qhov kub thiab txias. hom khoom siv feem ntau yog hfe59-1-

Nickel tooj dag
Nickel thiab tooj liab tsim ib qho kev daws teeb meem txuas ntxiv, nthuav dav hauv cheeb tsam -theem. Ntxiv nickel rau tooj dag zoo heev txhim kho nws cov corrosion kuj nyob rau hauv ob qho tib si cua thiab dej hiav txwv.

Tin Brass
Ntxiv cov tin rau tooj dag zoo txhim kho cov hlau tsis muaj cua sov, tshwj xeeb tshaj yog nws tsis kam rau seawater corrosion. Qhov no yog vim li cas tin tooj dag hu ua "naval brass". tin dissolves rau hauv cov khoom siv tooj liab-raws li kev daws teeb meem thiab txhim kho nws lub zog.

Cheebtsam ntawm Lead Brass

Cov hlau lead yog dab tsi tiag tiag ua los ntawm? Niaj hnub no, txhuas tooj dag yog tsim los ntawm tsis yog tooj liab thiab zinc. Ib qho me me ntawm lwm cov ntsiab lus, xws li arsenic, lead, phosphorus, aluminium, manganese, los yog silicon, ntxiv rau ntxiv rau nws cov khoom. Feem ntau, tooj dag muaj 67% tooj liab thiab 33% zinc. Qhov piv no tuaj yeem hloov kho kom tsim tau ntau hom tooj dag uas haum rau kev siv tshwj xeeb.

Kev sib xyaw ntawm Lead Brass

Txhawm rau txiav txim siab qhov purity ntawm txhuas txhuas, lub hauv paus ntsiab lus archimedes tuaj yeem siv los ntsuas qhov ntim thiab qhov loj ntawm cov qauv, tom qab ntawd qhov kev faib ua feem ntawm tooj liab hauv tooj dag tuaj yeem xam raws li qhov ntom ntawm tooj liab thiab zinc.common tooj dag yog ib qho alloy ntawm tooj liab thiab zinc. Thaum cov ntsiab lus zinc tsawg dua 35%, nws tuaj yeem yaj hauv tooj liab los ua ib theem qauv, uas yog hu ua ib-theem tooj dag. Cov qauv no muaj cov yas zoo thiab yog qhov zoo tagnrho rau txias thiab kub pressing.thaum cov ntsiab lus zinc nyob ntawm 36% mus rau 46%, muaj ib theem thiab cov tooj liab-zinc-raws li cov khoom siv, uas yog hu ua ob-theem tooj dag. . cov theem txo cov yas ntawm tooj dag thiab ua kom nws lub zog tensile, ua rau nws tsuas yog haum rau kev kub siab ua. Yog tias zinc cov ntsiab lus tseem nce ntxiv, lub zog tensile yuav txo qis, ua rau nws tsis muaj txiaj ntsig.

Cov khoom ntawm Lead Brass

Lead tsis soluble nyob rau hauv ib tug tooj liab matrix thiab yog vim li cas lead yog dispersed homogenously nyob rau hauv daim ntawv ntawm zoo globules nyob rau hauv lub microstructure. Cov hmoov txhuas ua cov roj nplua nyeem txo cov kev sib txhuam coefficient ntawm cov cuab yeej thiab cov khoom siv, tsim kev tsis sib xws uas txhawb cov nti tawg, txo cov txiav quab yuam thiab cov cuab yeej hnav tus nqi.

Yuav Ua Li Cas Ua Tau Lead Brass

Lub Sijhawm Saib Xyuas Thiab Tu Teem Sijhawm

Kev tshuaj xyuas tsis tu ncua ntawm tooj dag fittings yog thawj kauj ruam hauv lawv kev saib xyuas. Kev kuaj pom pom pom pom ntawm tarnishing, corrosion, lossis kev puas tsuaj yuav tsum tau ua ib ntus. tsim kom muaj ib lub sij hawm tu lub sij hawm raws li ib puag ncig tej yam kev mob thiab kev siv zaus yog qhov tseem ceeb heev. rau kev siv sab hauv tsev, lub sijhawm tu ib nrab xyoo yuav txaus, thaum sab nraum zoov lossis chaw tsim khoom yuav xav tau kev tshuaj xyuas ntau zaus thiab tu.

Cov txheej txheem ntxuav yooj yim

Thaum tu cov khoom siv tooj dag, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov tswv yim maj mam kom tsis txhob ua kom lub ntsej muag puas tsuaj los yog hloov cov fittings qhov ntev. pib los ntawm plua plav tawm ntawm cov av xoob lossis cov khib nyiab nrog cov ntaub mos muag. rau lub teeb tarnish, sib tov ntawm xab npum me me thiab dej sov yuav siv tau los maj mam so cov fittings.

Kev tshem tawm cov tawv tawv tarnish thiab Corrosion

Nyob rau hauv cov rooj plaub uas cov tooj dag fittings pom cov tawv nqaij tarnish los yog corrosion, yuav tsum tau muaj kev tu kom huv si. muab tshuaj txhuam ua los ntawm qhov sib npaug ntawm vinegar, ntsev, thiab hmoov nplej tuaj yeem siv rau thaj chaw cuam tshuam thiab sab laug rau lub sijhawm luv luv ua ntej yaug thiab ziab.

Daim Ntawv Thov Kev Tiv Thaiv Txheej

Kev siv cov txheej tiv thaiv tom qab ntxuav tuaj yeem pab tswj cov luster thiab tiv thaiv tooj dag fittings los ntawm tarnishing thiab corrosion. ib txheej nyias ntawm cov zoo tooj dag lossis cov lacquer ntshiab tuaj yeem ua tib zoo siv cov ntaub mos muag. xyuas kom meej tias cov fittings tau qhuav tag ua ntej siv cov txheej txheem tiv thaiv kom tsis txhob cuam tshuam cov dej noo, uas tuaj yeem ua rau corrosion.
