Ua ntej ntawm tag nrho cov, tooj liab yog categorized raws li dav pawg: ntshiab tooj liab, tooj dag, dawb tooj liab, bronze. Cov qhab nia yog sau nyob rau hauv daj.
Ua ntej, cov qib tooj liab ntshiab yog T1, T2, T3. Kev lag luam ntshiab tooj liab, T1 muaj qhov siab tshaj plaws purity, tooj liab + nyiaj cov ntsiab lus> 99.95%, tsis tas yuav tsum muaj cov ntsiab lus phosphorus, nrog rau cov khoom siv hluav taws xob zoo thiab thermal conductivity, corrosion kuj thiab kev ua tau zoo, tuaj yeem welded thiab brazed, tab sis cov kab ntau lawm. oxygen ntawm nws cov txheej txheem thiab siv nyob rau hauv qhov kub thiab txias txo qhov cua muaj qee yam cuam tshuam;
T2 ntawm tooj liab + nyiaj ntsiab lus> 99.9%, muaj tsawg impurities uas txo cov hluav taws xob thiab thermal conductivity, kev ua tau zoo zoo ib yam li T1;
T3's purity yog qhov tsawg, nws cov ntsuas kev ua tau zoo me ntsis qis dua rau T1 thiab T2.
Ntshiab tooj liab T1, T2, T3 feem ntau siv nyob rau hauv cov xov hlau, cables, conductive screws thiab lwm yam conductive kev kawm yuav tsum tau ntawm high zaus.
TU1, TU2: tooj liab tsis muaj oxygen. Nyob rau hauv lub hauv paus ntawm ntshiab tooj liab kom ntxiv txo cov pa oxygen, nrog ntau dua purity thiab zoo conductive zog, feem ntau yog siv nyob rau hauv nruj raws li cov ntsiab lus ntawm cov pa oxygen ntawm hluav taws xob, hluav taws xob thiab lwm yam kev lag luam.
Thib ob, tooj dag
Ordinary tooj dag:
H59: Muaj txog 59% tooj liab, qhov seem yog zinc. Lub zog, hardness, tab sis kuj tsis zoo plasticity, nyob rau hauv lub kub lub xeev muaj peev xwm kuj zoo dua tiv thaiv kev ua hauj lwm, corrosion kuj nyob rau hauv feem ntau, tus nqi yog pheej yig dua, feem ntau siv nyob rau hauv dav siv machinery qhov chaw, vuam, kub xuas nrig ntaus thiab kub qhov chaw.
H62: tooj liab cov ntsiab lus ntawm txog 62%, muaj cov khoom siv zoo, zoo plasticity nyob rau hauv lub xeev kub, txias plasticity kuj zoo, zoo txiav, yooj yim brazing thiab vuam, corrosion kuj, tab sis yooj yim los tsim corrosion rupture, yog ib tug dav siv ntau yam. ntawm cov tooj dag ntau, tuaj yeem siv rau ntau yam kev sib sib zog nqus nqus thiab khoov ntawm qhov chaw tsim khoom, xws li pins, rivets, washers, txiv ntseej, conduits, barometer springs, sieve mesh, radiator qhov chaw thiab lwm yam.
H65: kev ua tau zoo ntawm H68 thiab H62, siab zog thiab yas, tuaj yeem tiv taus txias thiab kub ua haujlwm, tab sis muaj kev nyiam rau corrosion rupture, feem ntau siv hauv cov khoom siv me me, cov khoom siv niaj hnub, me me springs, screws, rivets thiab txhua yam khoom.
H68: tooj liab cov ntsiab lus ntawm kwv yees li 68%, nrog cov yas zoo heev (yog qhov zoo tshaj plaws hauv tooj dag) thiab lub zog siab, kev ua haujlwm zoo, yooj yim rau vuam, feem ntau siv rau hauv qhov chaw txias txias thiab qhov sib sib zog nqus nqus, xws li radiator shells , conduits, bellows, plhaub, gaskets thiab lwm yam.
Complex tooj dag: HPb59-1: Nws yog ib hom tooj dag yooj yim txiav, uas muaj cov hmoov txhuas ntxiv rau tooj liab thiab zinc. Qhov sib ntxiv ntawm cov hmoov txhuas txhim kho qhov kev ua tau zoo ntawm cov tooj dag, thiab nws feem ntau yog siv rau hauv qhov chaw uas yuav tsum tau muaj kev ua haujlwm siab, xws li cov ntsia hlau thiab cov txiv ntoo. HFe58-1-1: tooj dag muaj cov khoom siv hlau, qhov sib ntxiv ntawm cov hlau txhim kho lub zog thiab tawv tawv ntawm tooj dag, haum rau qee lub sijhawm uas yuav tsum muaj lub zog siab.
Thib peb, bronze
Tin bronze: QSn 4-3: Muaj li ntawm 4% ntawm tin thiab 3% zinc. Muaj kev hnav zoo, kev tiv thaiv corrosion thiab elasticity, tuaj yeem siv rau kev tsim cov springs, bearings, gears thiab lwm yam hnav-resistant qhov chaw, tab sis kuj feem ntau siv nyob rau hauv zus tau tej cov teeb thiab lanterns caij nplooj ntoos hlav phaj, hloov lub caij nplooj ntoos hlav phaj thiab lwm yam. cov kev xav tau ntawm elasticity.
QSn6.
Aluminium bronze: QAl5: txhuas cov ntsiab lus ntawm li 5%, nrog rau siab zog thiab corrosion kuj, nyob rau hauv cov huab cua, dej hiav txwv thiab lwm yam ib puag ncig nrog zoo corrosion kuj, feem ntau siv nyob rau hauv lub tsim ntawm lub nkoj qhov chaw, tshuaj machinery qhov chaw.
QAl9-2: siab dua txhuas cov ntsiab lus, lub zog thiab hardness dua QAl5 siab dua, tuaj yeem siv los tsim cov khoom muaj zog hnav-resistant thiab corrosion-resistant qhov chaw.
Beryllium bronze: QBe2: beryllium cov ntsiab lus ntawm li 2%, nrog lub zog siab heev, hardness thiab elasticity, nrog rau cov hluav taws xob zoo thiab thermal conductivity, feem ntau siv rau hauv kev tsim cov cuab yeej precision, cov twj paj nruag, cov khoom siv elastic, hnav-tiv taus qhov chaw, xws li raws li moos thiab watches clockwork, caij nplooj ntoos hlav phaj.
Plaub, dawb tooj liab
Ordinary dawb tooj liab: B19: npib tsib xee cov ntsiab lus ntawm txog 19%, nrog rau siab zog thiab corrosion kuj, ruaj khov lub cev nyob rau hauv chav tsev kub, feem ntau siv nyob rau hauv kev tsim cov precision instruments, thermocouples, moos qhov chaw.
B30: nickel cov ntsiab lus ntawm txog 30%, zoo dua corrosion kuj, feem ntau siv hauv cov twj paj nruag thiab cov khoom siv kho mob.
Complex dawb tooj liab: BZn15-20: dawb tooj liab uas muaj zinc, ntxiv zinc txhim kho lub zog thiab plasticity ntawm tooj liab dawb, tuaj yeem siv rau kev tsim khoom ntawm qee qhov chaw ua haujlwm.
BFe30-1-1: tooj liab dawb uas muaj cov ntsiab lus hlau, ntxiv cov hlau los txhim kho corrosion kuj thiab lub zog ntawm tooj liab dawb, haum rau qee qhov kev xav tau ntau dua rau kev tiv thaiv corrosion thiab lub zog ntawm lub sijhawm.
