Yakadzika Kuwedzera Alloy Kovar 4J29 Wire, 29hk Wire yegirazi Kuisa Alcoy Alloy Afday Fungidzira mufananidzo

Yakaderera Kuwedzera Alloy Kovar 4J29 Wire, 29hk waya yegirazi inosimbisa alloy

Tsananguro pfupi:

Alloy-4J29 (Kuwedzera Alloy)
(Zita Rakafanana: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 anozivikanwa seKovar Alloy. Yakagadzirwa kuti isangane neinodiwa yegirazi rakavimbika Mazhinji masimbi haagoni kusimbisa kusvika kugirazi nekuti yavo coefficient yekuwedzera kwekuwedzera haina kufanana negirazi, saka kubatana kwekutora kwekunetseka nekuda kwekuwedzera kwemitengo yegirazi uye simbi inokonzeresa kupaza.

Alloy-4J29 Haana kungowedzera kuwedzera kufanana negirazi, asi yayo isisoni fanter Chemicals, inosungira kusvika girazi kuburikidza neyepakati oxide layer yeiyo nickel oxide uye cobalt oxide; Chikamu chedare resimbi rwakaderera nekuda kwekudzikiswa kwayo nejoko. Iyo Bond Simba inovimbika kwazvo pane iyo oxide layer gobvu uye hunhu. Kuvapo kwaCobalt kunoita kuti nzombe ivate ive nyore kunyungudika nekuvhurwa mugirazi rakanyungudutswa. Grey, grey-yebhuruu kana grey-brown brown ruvara rinoratidza chisimbiso chakanaka. Ruvara rwesimbi rinoratidza kushaya nzombe, nepo dema dema ichiratidza kunyanyisa oxided simbi, mune zvese zviitiko zviri zviviri zvichitungamira kune isina kusimba mubatanidzwa.

Chikumbiro:Kunyanya kushandiswa mumagetsi vacupuum zvikamu uye kusimuka kudzora, kuvhundutsa tube, kushamwaridzana, chisimbiso plug, nyanzvi, brackets, brackets uye kumwe kushaikwa kwedzimba.
