High Precision Custom Brass Tube Thiab Khoom Qws
Kev ntsuas purity
Qhov purity ntawm tooj dag tuaj yeem ntsuas tau siv lub hauv paus ntsiab lus Archimedes, qhov twg qhov ntim thiab qhov loj ntawm cov qauv ntsuas, thiab tom qab ntawd cov feem pua ntawm tooj liab muaj nyob rau hauv tooj dag tuaj yeem xam raws li qhov ntom ntawm tooj liab thiab qhov ntom ntawm zinc.
Ordinary tooj dag
Nws yog ib qho alloy ntawm tooj liab thiab zinc.
Thaum cov ntsiab lus zinc tsawg dua 35%, zinc tuaj yeem yaj hauv tooj liab los ua ib theem alpha, hu ua ib-theem tooj dag, zoo plasticity, haum rau kev kub thiab txias.
Thaum cov ntsiab lus zinc yog 36% ~ 46%, muaj α ib theem thiab β cov kua tshuaj raws li tooj liab thiab zinc, uas yog hu ua biphasic tooj dag, β theem ua rau tooj dag plasticity txo thiab tensile zog nce, tsuas yog haum rau kev kub siab ua.
Yog tias peb txuas ntxiv mus ntxiv cov feem ntau ntawm zinc, lub zog tensile txo qis thiab tsis muaj nqi siv.
Tus lej yog qhia los ntawm "H + tus lej", H txhais tau tias tooj dag, thiab tus lej txhais tau tias qhov loj ntawm tooj liab.
Piv txwv li, H68 txhais tau hais tias tooj dag muaj 68% tooj liab thiab 32% zinc, thiab tooj dag yog ua ntej los ntawm lo lus "Z", xws li ZH62.
Piv txwv li, ZCuZnzn38 txhais tau hais tias cov tooj dag casting nrog 38% zinc thiab cov nyiaj seem ntawm tooj liab.
H90, H80 yog ib-theem tooj dag, golden daj.
H59 yog duplex tooj dag, uas yog dav siv rau cov qauv ntawm cov khoom siv hluav taws xob, xws li bolts, txiv ntseej, ntxhua khaub ncaws, springs thiab lwm yam.
Feem ntau, ib leeg-theem tooj dag yog siv rau kev ua kom txias deformation thiab dual-theem tooj dag yog siv rau kub deformation ua.
Tshwj xeeb tooj dag
Cov khoom siv ntau yam tsim los ntawm kev ntxiv lwm cov ntsiab lus alloying rau cov khoom siv tooj dag hu ua tooj dag tshwj xeeb.Cov ntsiab lus feem ntau ntxiv yog txhuas, tin, txhuas, thiab lwm yam, thiab raws li tuaj yeem hu ua txhuas tooj dag, tooj dag, txhuas tooj dag.Lub hom phiaj ntawm kev ntxiv alloying ntsiab.Lub hom phiaj tseem ceeb yog ua kom lub zog tensile thiab txhim kho cov txheej txheem.
Cov cai: "H + lub cim ntawm lub ntsiab tseem ceeb ntxiv (tshwj tsis yog zinc) + pawg loj ntawm tooj liab + cov feem loj ntawm lub ntsiab ntxiv + cov feem ntau ntawm lwm cov ntsiab lus".
Piv txwv li: HPb59-1 qhia tias qhov loj ntawm tooj liab yog 59%, feem ntau ntawm cov hlau lead uas muaj cov ntsiab lus ntxiv yog 1%, thiab qhov sib npaug ntawm zinc yog txhuas txhuas.
Cov khoom siv dag zog ntawm tooj dag sib txawv nrog cov ntsiab lus zinc vim qhov sib txawv ntawm zinc hauv tooj dag.Rau α tooj dag, ob qho tib si σb thiab δ nce tsis tu ncua raws li cov ntsiab lus zinc nce.Rau (α + β) tooj dag, chav tsev kub lub zog nce ntxiv mus txog thaum cov ntsiab lus zinc nce mus txog 45%.Yog tias cov ntsiab lus zinc nce ntxiv, lub zog txo qis vim qhov pom ntawm cov r-theem ntau dua (Cu5Zn8 compound-raws li cov kua) hauv lub koom haum alloy.(Lub chav tsev kub plasticity ntawm (α + β) tooj dag ib txwm txo qis nrog qhov nce ntawm zinc cov ntsiab lus. Yog li ntawd, tooj liab-zinc alloys nrog zinc cov ntsiab lus ntawm ntau tshaj 45% tsis muaj nuj nqis.
Ordinary tooj dag yog siv nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv xws li dej tank siv, dej mov thiab cov kav dej, medallions, corrugated kav, serpentine kav, condensation kav, plhaub thiab ntau yam complex zoo li tus punching khoom, me me hardware, thiab lwm yam. zinc cov ntsiab lus los ntawm H63 txog H59, lawv tuaj yeem tiv taus lub xeev kub ua haujlwm, thiab feem ntau yog siv rau ntau qhov chaw ntawm cov tshuab thiab cov khoom siv hluav taws xob, stamping qhov chaw thiab cov twj paj nruag.
Txhawm rau txhim kho corrosion kuj, lub zog, hardness thiab machinability ntawm tooj dag, ib qho me me (feem ntau 1% mus rau 2%, ob peb txog 3% mus rau 4%, tsawg heev txog 5% mus rau 6%) ntawm tin, txhuas, manganese, hlau, silicon, npib tsib xee, txhuas thiab lwm yam khoom yog ntxiv rau tooj liab-zinc alloy los ua ib tug ternary, quaternary, los yog tsib lub ntsiab alloy, uas yog complex tooj dag, tseem hu ua tooj dag tshwj xeeb.
Brass muaj zog hnav tsis kam, tooj dag feem ntau siv hauv kev tsim cov li qub, cov kav dej, cua txias sab hauv thiab sab nraud tshuab txuas cov kav dej thiab radiators, thiab lwm yam.
Lead tooj dag
Lead yog xyaum insoluble nyob rau hauv tooj dag thiab muab faib rau ntawm grain ciam teb nyob rau hauv daim ntawv ntawm dawb masses.Muaj ob hom txhuas txhuas raws li lawv lub koom haum: α thiab (α + β).α txhuas tooj dag tuaj yeem tsuas yog txias deformed lossis kub extruded vim muaj kev phom sij ntawm cov hlau lead thiab cov yas qis ntawm qhov kub thiab txias.(α + β) txhuas tooj dag muaj cov yas zoo ntawm qhov kub thiab txias tuaj yeem ua rau forged.
Tin tooj dag
Qhov sib ntxiv ntawm tin rau tooj dag tuaj yeem txhim kho cov cua sov ntawm cov hlau, tshwj xeeb tshaj yog txhawm rau txhim kho lub peev xwm tiv thaiv corrosion ntawm seawater, yog li tin tooj dag muaj lub npe ntawm "naval brass".
Tin tuaj yeem yaj mus rau hauv cov khoom siv tooj liab-raws li kev daws teeb meem, cov tshuaj muaj zog ntxiv zog.Txawm li cas los xij, nrog kev nce ntawm cov ntsiab lus tin, cov hlau yuav tshwm sim r-theem (CuZnSn compound), uas tsis tsim nyog rau cov yas deformation ntawm cov hlau, yog li cov ntsiab lus tin ntawm cov tooj dag feem ntau nyob rau hauv thaj tsam ntawm 0.5% mus rau 1.5%.
Cov tin brasses feem ntau yog HSn70-1, HSn62-1, HSn60-1, thiab lwm yam. Cov qub yog alpha alloy nrog cov yas siab thiab tuaj yeem ua tiav los ntawm kev txias lossis kub.Ob qib tom kawg muaj (α + β) lub koom haum ob-theem, thiab feem ntau tshwm sim me me ntawm r-theem, chav tsev kub plasticity tsis siab, thiab tsuas yog tuaj yeem deformed hauv lub xeev kub.
Manganese tooj dag
Manganese muaj ib tug loj solubility nyob rau hauv cov khoom tooj dag.Ntxiv 1% mus rau 4% ntawm manganese hauv tooj dag, tuaj yeem txhim kho lub zog thiab corrosion tsis kam ntawm cov hlau, tsis txo nws cov plasticity.
Manganese tooj dag muaj (α + β) lub koom haum, feem ntau siv yog HMn58-2, thiab kev ua haujlwm siab hauv lub xeev txias thiab kub yog qhov zoo heev.
Ferrous tooj dag
Nyob rau hauv cov hlau tooj dag, hlau precipitates raws li ib feem ntawm hlau-nplua nuj theem, refines nplej raws li nuclei, thiab tiv thaiv kev loj hlob ntawm recrystallized nplej, yog li txhim kho cov neeg kho tshuab zog thiab txheej txheem zog ntawm cov hlau.Cov ntsiab lus hlau hauv ferrobrass feem ntau yog qis dua 1.5%, thiab nws lub koom haum yog (α + β), muaj zog thiab tawv, zoo plasticity ntawm qhov kub thiab txias, thiab deformable hauv lub xeev txias.Qib siv feem ntau yog Hfe59-1-1.
Nickel tooj dag
Nickel thiab tooj liab tuaj yeem tsim cov kev daws teeb meem txuas ntxiv, nthuav dav thaj tsam alpha theem.Qhov sib ntxiv ntawm npib tsib xee rau tooj dag tuaj yeem txhim kho qhov corrosion kuj ntawm tooj dag nyob rau hauv qhov chaw thiab dej hiav txwv.Nickel kuj nce qhov kub ntawm recrystallization ntawm tooj dag thiab txhawb kev tsim cov nplej zoo.
HNi65-5 npib tsib xee tooj dag muaj ib lub koom haum alpha ib-theem, nrog cov yas zoo ntawm chav tsev kub, kuj tuaj yeem deformed nyob rau hauv lub xeev kub, tab sis cov ntsiab lus ntawm impurities txhuas yuav tsum nruj me ntsis tswj, txwv tsis pub nws yuav hnyav deteriorate lub kub ua hauj lwm yam ntxwv. lub alloy.
Thaum tshav kub kub ua haujlwm kub 750 ~ 830 ℃;annealing kub 520 ~ 650 ℃;Tsis tshua muaj kub annealing kub 260 ~ 270 ℃ kom tshem tawm cov kev ntxhov siab sab hauv.
