Kovar alloy 4j29

4J29 alloy inozivikanwawo seKovar alloy.Iyo alloy ine mutsara wekuwedzera coefficient yakafanana neye borosilicate yakaoma girazi pa20 ~ 450 ℃, yakakwira Curie point uye yakanaka yakaderera tembiricha microstructure kugadzikana.Iyo oxide film yealloy yakaoma uye inogona kunyatsopinzwa negirazi.Uye haidyidzane ne mercury, yakakodzera kushandiswa muchiridzwa chine mercury discharge.Ndiyo huru yekuisa chisimbiso zvimiro zvemagetsi vacuum mudziyo.Inoshandiswa kugadzira Fe-Ni-Co alloy strip, bar, plate uye pombi ine hard glass/ceramic matching sealing, inonyanya kushandiswa muvacuum electronics, magetsi emagetsi nemamwe maindasitiri.
4J29 Chikumbiro chekuongorora uye zvakakosha zvinodiwa
Iyo alloy ndeye yakajairika Fe-Ni-Co yakaoma girazi sealing alloy inowanzoshandiswa munyika.Yakave ichishandiswa nefekitari yekubhururuka kwenguva yakareba uye kuita kwayo kwakagadzikana.Inonyanya kushandiswa kuisa chisimbiso chegirazi chemagetsi vacuum zvinhu senge emission chubhu, oscillation chubhu, ignition chubhu, magnetron, transistor, sealing plug, relay, integrated circuit lead line, chassis, shell, bracket, etc. yekuwedzera coefficient yegirazi yakasarudzwa uye alloy inofanira kufananidzwa.Iyo yakadzika tembiricha yetishu kugadzikana inoedzwa zvakanyanya maererano nekushandiswa tembiricha.Kurapa kwakakodzera kwekupisa kunofanirwa kuitwa mukugadzirisa maitiro kuti ive nechokwadi chekuti zvinhu zvine kunaka kwakadzika kudhirowa kuita.Paunenge uchishandisa zvinhu zvekuumba, kusimba kwayo kwemhepo kunofanira kunyatsotariswa.
Covar alloy nekuda kweiyo cobalt yemukati, chigadzirwa hachina kupfeka.
Inogona kuiswa chisimbiso nyore nyore ne molybdenum boka girazi, uye iyo yakazara pamusoro peiyo workpiece inoda goridhe plating.
4J29 Formability:
Iyo alloy ine yakanaka inotonhora uye inopisa yekushanda zvivakwa, uye inogona kugadzirwa mumhando dzakasiyana dzakaoma dzezvikamu.Zvisinei, kupisa mumhepo ine sulfuri inofanira kudziviswa.Mukutonhora kwekukunguruka, kana kutonhora kwemutsetse wemutsetse wakakura kupfuura 70%, iyo anisotropy yepurasitiki inozo shandiswa mushure mekuvharwa.Kana iyo inotonhora dhizaini iri muchikamu che10% ~ 15%, zviyo zvinokura nekukurumidza mushure mekuvhara, uye iyo yepurasitiki anisotropy yealloy ichagadzirwa zvakare.Iyo yepurasitiki anisotropy ishoma kana iyo yekupedzisira strain rate iri 60% ~ 65% uye saizi yezviyo i7 ~ 8.5.
4J29 Welding zvivakwa:
Iyo alloy inogona kugadzirwa nemhangura, simbi, nickel uye mamwe masimbi nebrazing, fusion welding, resistance welding, etc. Kana iyo zirconium iri mu alloy yakakura kupfuura 0.06%, inokanganisa kunaka kweplate uye kunyange kugadzira. weld crack.Alloy isati yavharwa negirazi, inofanira kucheneswa, inoteverwa nepamusoro tembiricha wet hydrogen kurapwa uye pre-oxidation kurapwa.
4J29 Surface kurapwa maitiro: Kurapa kwepamusoro kunogona kuita jecha, kupukuta, kunhonga.
Mushure mekunge zvikamu zvakavharwa negirazi, iyo oxide firimu inogadzirwa panguva yekuisa chisimbiso inofanira kubviswa kuti zvive nyore welding.Zvikamu zvinogona kudziyisa kusvika ku70 ℃ mune aqueous solution ye10% hydrochloric acid +10% nitric acid, uye yakanyungudutswa kwe2 ~ 5min.
Iyo alloy ine yakanaka electroplating performance, uye pamusoro inogona kuve yegoridhe-yakaputirwa, sirivheri, nickel, chromium uye mamwe simbi.Kuti ufambise welding kana kupisa kusungirirana pakati pezvikamu, inowanzoputirwa nemhangura, nickel, goridhe uye tini.Kuti uvandudze conductivity yeakakwira frequency yazvino uye kuderedza kusangana kwekupokana kuti ive nechokwadi cheyakajairika cathode emission maitiro, goridhe nesirivha zvinowanzoputirwa.Kuti uvandudze kushora kwechigadzirwa, nickel kana goridhe inogona kuiswa.
4J29 Kucheka nekukuya kuita:
Maitiro ekucheka eiyo alloy akafanana neaya austenitic simbi isina tsvina.Kugadzira uchishandisa yakakwira yekumhanyisa simbi kana carbide chishandiso, yakaderera kumhanya yekucheka kugadzirisa.Inotonhorera inogona kushandiswa pakucheka.Iyo alloy ine yakanaka yekukuya kuita.
4J29 Zvinonyanya kukosha:
4J29 pombi isina musono, 4J29 simbi ndiro, 4J29 raundi simbi, 4J29 forgings, 4J29 flange, 4J29 mhete, 4J29 welded pombi, 4J29 simbi bhendi, 4J29 bhaa yakatwasuka, 4J29 waya uye inofananidzwa nesimbi keke, 9xJ29 simbi, 9xJ29 bar, 4J29 saizi musoro, 4J29 gokora, 4J29 tee, 4J29 4J29 zvikamu, 4J29 mabhaudhi uye nzungu, 4J29 fasteners, nezvimwe.
