Tungsten Copper Alloy tsvimbo
Tsanangudzo
Copper tungsten (CuW, WCu) yave ichizivikanwa seyakanyanya conductive uye erasion inopikisa composite zvinhu iyo inoshandiswa zvakanyanya semhangura tungsten electrode muEDM machining uye resistance welding applications, magetsi anobatika mune yakakwira voltage application, uye kupisa sinks uye zvimwe zvemagetsi zvekurongedza zvinhu. mumashandisirwo ekupisa.
Iyo yakawanda tungsten / mhangura ratios ndeyeWCu 70/30, WCu 75/25, uye WCu 80/20.Dzimwe nziyo dzinozivikanwa dzinosanganisira tungsten/mhangura 50/50, 60/40, uye 90/10.Mhando yezvinyorwa zviripo zvinobva kuCu 50 wt.% kusvika kuCu 90 wt.%.Yedu tungsten mhangura yechigadzirwa mhando inosanganisira yemhangura tungsten tsvimbo, foil, shiti, ndiro, chubhu, tungsten tsvimbo yemhangura, uye zvikamu zvemuchina.

Features
Munguva yekugadzirwa kwemhangura tungsten alloy, yakakwira kuchena tungsten inotsikirirwa, yakanyungudutswa uye yobva yapinzwa nemhangura isina oxygen mushure mekusimbisa matanho.Iyo yakasanganiswa tungsten copper alloy inopa homogeneous microstructure uye yakaderera mwero weporosity.Iko kusanganiswa kwemhangura conductivity ine tungsten yakakwira density, kuomarara, uye nzvimbo yakakwira yekunyungudika inoburitsa musanganiswa une zvakawanda zvakatanhamara zvezvinhu zvese zviri zviviri.Copper-infiltrated tungsten inozvirumbidza zvakadai sekukwirira kwepamusoro-tembiricha uye arc-erosion, yakanakisa kupisa uye magetsi conductivity uye yakaderera CTE (coefficient of thermal).
Iyo yemuviri uye yemagetsi zvivakwa uye nzvimbo yekunyunguduka yetungsten mhangura zvinhu zvichave zvakanaka kana zvinopesana nekukanganisa huwandu hwemhangura tungsten mumubatanidzwa.Semuenzaniso, sezvo mhangura yemhangura inowedzera zvishoma nezvishoma, magetsi uye kupisa kwemhepo uye kuwedzera kwekushisa kunoratidza tsika yekuve yakasimba.Zvisinei, kuwanda, kushorwa kwemagetsi, kuoma uye kusimba kuchave kusina simba kana kupindirwa nehuwandu hushoma hwemhangura.Naizvozvo, yakakodzera makemikari kuumbwa ndiyo yakanyanya kukosha kana uchifunga nezve tungsten mhangura kune chaiyo application inodiwa.
Kuwedzera kwekushisa kwepasi
High thermal uye magetsi conductivity
High arc resistance
Kushandiswa kwakaderera
Applications
Iko kushandiswa kweTungsten mhangura (W-Cu) kwakawedzera zvinooneka muminda yakawanda uye mashandisirwo nekuda kwekusiyana kwayo kwemuchina uye thermophysical zvimiro.Tungsten mhangura yemidziyo inoratidza yakakwira yakanakisa kuita muzvikamu zvekuoma, simba, conductivity, tembiricha yepamusoro, uye arc erosion kuramba.Yakave yakashandiswa zvakanyanya pakugadzirwa kwemagetsi ekubatanidza, kupisa sinkers uye kuparadzira, kufa-kunyura EDM electrodes uye mafuta jekiseni nozzles.
