Material:
4J28 (Fe-Ni Alloy, Kovar-mhando Glass-Sealing Alloy)

Zvinodiwa:
Inowanikwa mumadhayamita akasiyana-siyana (0.02 mm kusvika 3.0 mm), kureba kunogoneka

Applications:
Girazi-kune-simbi sealing, machubhu emagetsi, masensa, vacuum components, uye zvimwe midziyo yemagetsi chaiyo.

Surface Treatment:
Yakapenya pamusoro, isina oxide, yakavharwa kana kutonhora-inodhonzwa

Kurongedza:
Coil/Spool fomu, kuputira kwepurasitiki, bhegi rakavharwa-vacuum kana kurongedza kwakagadzirirwa pakukumbira.

Product Description:

4J28 alloy waya, inozivikanwawo seFe-Ni alloy waya, ndeye chaiyo yakapfava magineti uye girazi-sealing material. Iine kuumbwa kunonyanya kuumbwa nesimbi uye ingangoita 28% nickel, inopa yakasarudzika yekupisa yekuwedzera inofananidzwa negirazi yeborosilicate, ichiita kuti ishandiswe zvakanyanya mumagetsi kurongedza uye girazi-kune-simbi sealing application.

4J28 wayainoratidzira yakanakisa yekuisa chisimbiso zvivakwa, yakagadzikana magineti kuita, uye yakavimbika mechanicha maitiro. Inoshandiswa zvakanyanya mumachubhu emagetsi, hermetic packaging, semiconductor housings, uye yakakwirira-yakavimbika aerospace uye mauto zvikamu.

Features:

• Yakanakisa Girazi-kune-Metal Kuisa Chisimbiso: Yakanakira kupisa kwekuwedzera kuenderana ne borosilicate girazi kune yakasimba, hermetic zvisimbiso.

• Yakanaka Magnetic Properties: Inokodzera nyoro magineti application uye yakagadzikana magineti mhinduro

• Yakakwirira Dimensional Precision: Inowanikwa mu-ultra-fine diameters, chaiyo-inodhonzwa kune inonzwisisika yemagetsi zvikamu.

• Oxidation Resistance: Yakapenya pamusoro, oxidation-isina, yakakodzera vacuum uye yakakwirira-kuvimbika chisimbiso.

• Customizable: Zviyero, kurongedza, uye pamusoro pemamiriro ezvinhu anogona kugadzirwa kune chaiwo vatengi zvinodiwa

Applications:

• Machubhu emagetsi uye vacuum zvishandiso

• Girazi-kune-simbi yakavharwa relays uye masensa

• Semiconductor uye hermetic mapakeji

• Aerospace uye zvechiuto-giredhi zvemagetsi zvikamu
