1. Cov yam ntxwv ntawm cov ntshiab liab tooj liab: siab purity, zoo lub koom haum, tsis tshua muaj oxygen cov ntsiab lus.tsis muaj

Pores, trachoma, porosity, zoo heev hluav taws xob conductivity, siab precision ntawm qhov chaw ntawm lub electro-etched pwm, tom qab kev kho cua sov txheej txheem, lub electrode yog tsis-directional, haum rau nplua-txiav, nplua-txiav, kev ua tau zoo yog piv rau Nyiv lub ntshiab liab tooj liab, tus nqi yog pheej yig dua, nws yog ib qho kev xaiv Cov khoom nyiam rau imported tooj liab.Cu≥99.95% O<003Conductivity≥57ms/mHardness≥85.2HV

2. Chromium-tooj ​​liab yam ntxwv: zoo hluav taws xob thiab thermal conductivity, siab hardness, hnav-resistant thiab anti-explosion, feem ntau siv los ua ib tug conductive thaiv.

3. Beryllium tooj liab khoom: Beryllium tooj liab yog ib qho supersaturated khoom tov tooj liab-raws li alloy.Nws yog non-ferrous alloy nrog kev sib xyaw ua ke zoo ntawm cov khoom siv kho tshuab, lub cev muaj zog, tshuaj lom neeg thiab corrosion kuj.Tom qab kev daws teeb meem thiab kev laus, nws muaj qhov sib npaug rau cov hlau tshwj xeeb.Lub siab zog txwv, elastic txwv, tawm los txwv thiab qaug zog txwv.Nyob rau tib lub sij hawm, nws muaj hluav taws xob conductivity, thermal conductivity, siab hardness thiab hnav tsis kam, siab creep kuj thiab corrosion kuj.Vuam electrode cov ntaub ntawv rau cov tshuab tuag-casting, txhaj tshuaj molding tshuab punches, hnav-resistant thiab corrosion-resistant ua hauj lwm, thiab lwm yam., beryllium tooj liab strips yog siv nyob rau hauv micro-motor txhuam, xov tooj ntawm tes roj teeb, computer connectors, ntau yam kev sib cuag, springs, clips, gaskets, diaphragms, Membrane thiab lwm yam khoom.Nws yog ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom lag luam hauv kev tsim kho kev lag luam hauv tebchaws.Ceev 8.3g/cm3 Hardness 36-42HRC Hluav taws xob conductivity ≥18% IACS tensile zog ≥1000Mpa Thermal conductivity ≥105w/m.k20 ℃

4. Cov yam ntxwv ntawm tungsten thiab tooj liab: thaum hmoov metallurgy yog siv rau pwm ua los ntawm tungsten steel, siab carbon steel thiab kub resistant super-hard alloy, thaum hluav taws xob corrosion yuav tsum tau, vim qhov loj poob thiab qeeb ceev ntawm cov electrodes zoo tib yam, tungsten tooj liab yog cov khoom siv zoo tagnrho.Khoov zog ≥667Mpa

Ceev 14g/cm3 Hardness ≥ 184HV Conductivity ≥ 42% IACS.

Niaj hnub no, tooj liab tseem muaj ntau yam kev siv.Lub conductivity ntawm tooj liab yog thib ob tsuas yog nyiaj, qeb thib ob ntawm cov hlau, thiab siv dav hauv kev lag luam hluav taws xob.

Tooj liab yog ib qho yooj yim los tsim cov alloys nrog lwm cov hlau.Muaj ntau hom tooj liab alloys.Piv txwv li, bronze (80% Cu, 15% Sn, 5% Zn) yog tawv, siab hardness thiab yooj yim rau cam khwb cia;tooj dag (60% Cu, 40% Zn) yog dav siv.Siv los ua cov cuab yeej cuab tam;cupronickel (50% -70% Cu, 18% -20% Ni, 13% -15% Zn) yog siv los ua cov cuab yeej.

tooj liab thiab hlau, manganese, molybdenum, boron, zinc, cobalt thiab lwm yam khoom siv tau raws li cov khoom siv chiv.Cov ntsiab lus kab yog qhov tseem ceeb rau lub neej ib txwm ua haujlwm ntawm cov nroj tsuag.Lawv tuaj yeem txhim kho cov haujlwm ntawm cov enzymes, txhawb kev tsim cov piam thaj, cov hmoov txhuv nplej siab, cov protein, nucleic acids, vitamins thiab enzymes, uas muaj txiaj ntsig zoo rau kev loj hlob ntawm cov nroj tsuag.

Tooj liab plays lub luag haujlwm tseem ceeb hauv kev ua neej nyob.Muaj ntau tshaj 30 hom proteins thiab enzymes hauv tib neeg lub cev uas muaj tooj liab.Tam sim no nws paub tias qhov tseem ceeb tshaj plaws ntawm lub cev muaj zog ntawm tooj liab yog ceruloplasmin hauv tib neeg cov ntshav, uas muaj cov haujlwm ntawm catalyzing lub physiological metabolism ntawm hlau.Tooj liab kuj ua rau muaj peev xwm ntawm cov qe ntshav dawb kom rhuav tshem cov kab mob thiab txhim kho kev kho mob ntawm qee yam tshuaj.Txawm hais tias tooj liab yog ib qho tseem ceeb, yog tias noj ntau dhau, nws tuaj yeem ua rau ntau yam kab mob.

1. Kev ua tau zoo

Tooj liab muaj lub cev zoo thiab tshuaj lom neeg xws li hluav taws xob conductivity, thermal conductivity, corrosion kuj thiab ductility.Cov hluav taws xob conductivity thiab thermal conductivity yog qhov thib ob tsuas yog nyiaj, thiab cov tooj liab ntshiab tuaj yeem rub mus rau hauv cov xov tooj tooj liab nyias nyias kom nyias nyias nyias.Cov seem tshiab ntawm cov tooj liab ntshiab yog sawv liab, tab sis tom qab tooj liab oxide zaj duab xis yog tsim rau ntawm qhov chaw, qhov tsos yog xim liab, yog li nws feem ntau hu ua liab tooj liab.

Tooj liab tsuas yog tooj liab ntshiab

, tooj liab tuaj yeem ua ke nrog tin, zinc, npib tsib xee thiab lwm yam hlau los ua cov hlau sib txawv nrog cov yam ntxwv sib txawv, xws li tooj liab, tooj dag thiab cupronickel.Yog tias zinc ntxiv rau cov tooj liab ntshiab (99.99%), nws hu ua tooj dag.Piv txwv li, tooj dag zoo tib yam uas muaj 80% tooj liab thiab 20% zinc yog siv nyob rau hauv condensers ntawm fais fab nroj tsuag thiab tsheb radiators;Ntxiv nickel yog hu ua dawb tooj liab, tus so yog hu ua bronze.Tsuas yog zinc thiab npib tsib xee, tag nrho cov tooj liab alloys nrog rau lwm cov hlau yog hu ua tooj liab, thiab cov khoom dab tsi ntxiv yog hu ua lub caij.Qhov tseem ceeb tshaj plaws bronzes yog tin phosphor bronze thiab beryllium bronze.Piv txwv li, tin bronze muaj keeb kwm ntev heev ntawm daim ntawv thov hauv kuv lub teb chaws, thiab yog siv los nrum tswb, tripods, suab paj nruag thiab cov hlab ntsha.Tin bronze kuj tseem siv tau ua bearings, bushings thiab hnav qhov chaw, thiab lwm yam.

Cov hluav taws xob conductivity ntawm cov tooj liab ntshiab yog txawv, thiab lub zog thiab corrosion kuj ntawm tooj liab tuaj yeem txhim kho tau zoo los ntawm kev sib tsoo.Qee qhov ntawm cov alloys no hnav-tiv taus thiab muaj cov khoom zoo casting, thiab qee qhov muaj cov khoom siv zoo dua qub thiab tiv thaiv corrosion.

2. Lub hom phiaj

Vim tooj liab muaj cov khoom zoo tshaj plaws uas tau hais los saum toj no, nws muaj ntau yam kev lag luam siv.Xws li kev lag luam hluav taws xob, kev tsim tshuab, kev thauj mus los, kev tsim kho thiab lwm yam.Tam sim no, tooj liab feem ntau yog siv rau hauv kev tsim cov xov hlau, kev sib txuas lus cables thiab lwm yam khoom tiav xws li lub tshuab hluav taws xob, lub tshuab hluav taws xob rotors thiab cov twj siv hluav taws xob thiab cov ntsuas hauv qhov kev lag luam hluav taws xob thiab hluav taws xob, uas suav txog li ib nrab ntawm tag nrho cov kev lag luam. xav tau.Tooj liab thiab tooj liab alloys nyob rau hauv ib qho tseem ceeb txoj hauj lwm nyob rau hauv lub computer chips, integrated circuits, transistors, luam Circuit Court boards thiab lwm yam khoom siv thiab khoom siv.Piv txwv li, cov transistor coj siv chromium-zirconium-tooj ​​liab alloy nrog hluav taws xob conductivity thiab siab thermal conductivity.Tsis ntev los no, lub tuam txhab computer nto moo thoob ntiaj teb IBM tau txais yuav tooj liab los hloov txhuas hauv silicon chips, uas yog qhov tseeb ntawm kev siv cov hlau qub tshaj plaws hauv tib neeg hauv semiconductor technology.
