Beryllium copper ngati castable wrought alloy beryllium copper alloy, yomwe imadziwikanso kuti beryllium bronze, beryllium copper alloy.Ndi aloyi ndi zabwino makina, thupi ndi mankhwala mabuku katundu.Pambuyo pozimitsa ndi kutentha, imakhala ndi mphamvu zambiri, kusungunuka, kukana kuvala, kukana kutopa komanso kutentha.Panthawi imodzimodziyo, mkuwa wa beryllium umakhalanso ndi magetsi apamwamba., matenthedwe matenthedwe, kukana kuzizira komanso osagwiritsa ntchito maginito, palibe zopsereza zikakhudzidwa, zosavuta kuwotcherera komanso kulimba, kukana kwa dzimbiri mumlengalenga, madzi abwino ndi madzi a m'nyanja.
Ndizinthu zotanuka zapamwamba zomwe zimagwira ntchito bwino pakati pa ma alloys amkuwa.Imakhala ndi mphamvu zambiri, kulimba, kulimba, mphamvu ya kutopa, kutsika pang'ono zotanuka, kukana dzimbiri, kukana kuvala, kukana kuzizira, ma conductivity apamwamba, osagwiritsa ntchito maginito, ndipo palibe zopsereza zikakhudzidwa.Mndandanda wazinthu zabwino kwambiri zakuthupi, zamankhwala komanso zamakina.Mtundu wa mkuwa wa beryllium nthawi zambiri umasonyeza mitundu iwiri yofiira kapena yachikasu.Ndi zachilendo kuti mtundu wa beryllium mkuwa uwoneke wachikasu ndi wofiira, chifukwa mankhwala a okosijeni amapezeka panthawi yopanga ndi kusunga, ndipo mtundu umasintha.
Zigawo: Kachulukidwe 8.3g/cm3 Kuuma pamaso kuzimitsa 200-250HV Kuuma pambuyo kuzimitsa ≥36-42HRC Kuzimitsa kutentha 315℃≈600℉ Kuzimitsa nthawi 2 hours
Kutentha kofewetsa 930 ℃ Pambuyo kufewetsa, kuuma 135±35HV, mphamvu yamakokedwe ≥1000mPa
Mkuwa wa Beryllium umagawidwa kukhala wamkuwa wapamwamba wa beryllium ndi mkuwa wochepa wa beryllium.Mkuwa wapamwamba wa beryllium umatanthauza mkuwa wa beryllium wokhala ndi beryllium woposa 2.0.Beryllium mkuwa ndi kukana kuwotcherera ma elekitirodi zinthu kuwotcherera, ndi magetsi wabwino ndi matenthedwe madutsidwe ndi kuuma kwambiri.Powotcherera, ma elekitirodi amavala pang'ono, liwiro limakhala lachangu, ndipo mtengo wake ndi wotsika.
Njira Yopangira Beryllium Copper
Njira yopanga beryllium mkuwa imagawidwa m'magawo anayi: kupanga beryllium-copper master alloy ndi njira yochepetsera carbothermal, kusungunula kwa beryllium copper alloy, ingot of copper alloy ndi kupanga beryllium copper alloy plate, strip ndi strip.
Kupanga kwa beryllium-copper master alloys ndi carbothermal reduction kumatanthauza kuchepetsedwa kwachindunji kwa beryllium mu beryllium oxide ndi kaboni mumkuwa wosungunuka, ndikutsatiridwa ndi alloying mkuwa.Kupanga kwa beryllium-copper master alloy ndi kuchepetsa carbothermic mumakampani kumachitika mu ng'anjo yamagetsi yamagetsi.Ng'anjo yamagetsi yamagetsi imayikidwa mu chidebe chosindikizidwa.Wogwira ntchitoyo amavala chigoba cha gasi.% ya ufa wa kaboni umasakanizidwa mu mphero ya mpira ndi pansi, ndiyeno wosanjikiza wamkuwa, wosanjikiza wa beryllium oxide ndi carbon powder osakaniza amalowetsedwa mu ng'anjo yamagetsi yamagetsi m'magulu, amalimbikitsidwa ndi kusungunuka.Pamene utakhazikika kwa 950 madigiri Celsius - 1000 madigiri Celsius, aloyi dzina beryllium carbide, carbon, ndi yotsalira ufa tiwolokere, slag, ndiyeno kuponyera 2.25 makilogalamu kapena 5 kg ingots pa 950 digiri Celsius.
Mtengo womwe umagwiritsidwa ntchito posungunula beryllium copper alloy umaphatikizapo chitsulo chatsopano, zidutswa, secondary remelting charge ndi master alloy.
Beryllium nthawi zambiri amagwiritsa ntchito beryllium-copper master alloy (yokhala ndi beryllium 4%);nickel nthawi zina amagwiritsa ntchito zitsulo zatsopano, ndiko kuti, nickel electrolytic, koma ndi bwino kugwiritsa ntchito nickel-copper master alloy (muli 20% nickel);cobalt amagwiritsa ntchito cobalt-copper master alloy (Cobalt 5.5%), ndipo ena amagwiritsa ntchito cobalt weniweni;titaniyamu amawonjezedwa ndi titaniyamu-mkuwa master aloyi (wokhala 15% titaniyamu, ndipo ena alinso 27.4% titaniyamu), ndipo ena mwachindunji kuwonjezera siponji titaniyamu;magnesium ndi magnesium- Copper master alloy (yokhala ndi 35.7% magnesium) idawonjezedwa.
Chips (tchipisi mphero, kudula tchipisi, ndi zina zotero) ndi zing'onozing'ono zapangodya zomwe zimapangidwira panthawi yokonza, nthawi zambiri zimaponyedwa muzitsulo pambuyo pa kusungunula kwachiwiri monga smelting charge;kuwonjezera pa zinthu zomwe zasinthidwanso, pamene batching Ndizofalanso kuwonjezera zinyalala zotayira ndi makina opangira zinyalala mwachindunji ku ng'anjo.
Ingot ya beryllium copper alloy imagawidwa kukhala ingot yopanda vacuum ndi vacuum ingot.Njira zopanda vacuum ingot zoponyera zomwe zimagwiritsidwa ntchito popanga beryllium copper alloy alloy zimaphatikizapo kuponyera kwachitsulo chachitsulo, kuponyera kwa ingot popanda kutuluka, kuponyera kwa ingot mosalekeza komanso kuponyera kosalekeza.Njira ziwiri zoyambirira zimagwiritsidwa ntchito m'mafakitale omwe ali ndi masikelo ang'onoang'ono opanga.
Akatswiri adanena kuti kuti apeze ma beryllium-copper alloy ingots okhala ndi mpweya wochepa, kupatukana pang'ono, kuphatikizika pang'ono, ndi mawonekedwe a yunifolomu ndi wandiweyani wa kristalo, njira yabwino ndiyo kupukuta ingots pambuyo pa smelting smelting.Vacuum ingot casting imakhala ndi mphamvu yayikulu pakuwonetsetsa zomwe zili ndi zinthu zomwe zimatha oxidizable monga beryllium ndi titaniyamu.Pakafunika, gasi wa inert akhoza kuyambitsidwa kuti ateteze njira yoponyera ingot.
Tanthauzo la chithandizo cha kutentha kwa beryllium mkuwa: chithandizo cha kutentha kwa beryllium bronze Kutentha kwa beryllium bronze kungagawidwe mu mankhwala a annealing, chithandizo chamankhwala ndi ukalamba pambuyo pa chithandizo chamankhwala.
Chithandizo cha beryllium copper retreat (kubwerera) chimagawidwa kukhala: (1) Kufewetsa kwapakatikati, komwe kungagwiritsidwe ntchito kufewetsa mkati mwa kukonza.(2) Kutentha kokhazikika kumagwiritsidwa ntchito kuthetsa kupsinjika kwa makina komwe kumapangidwa panthawi ya akasupe olondola komanso kuwongolera, ndikukhazikitsa miyeso yakunja.(3) Kuchepetsa kupsinjika kumagwiritsidwa ntchito kuthetsa kupsinjika kwamakina komwe kumapangidwa pakumakina ndi kukonza.
