Izicelo:
Ukuvalwa kwengilazi kube yinsimbi, amashubhu kagesi, izinzwa, izingxenye ze-vacuum, kanye namanye amadivayisi kagesi anembile

Ukwelashwa Okuphezulu:
Ubuso obukhanyayo, obungena-oxide, obufakwe i-anneal noma obudonswa kubanda

Ukupakisha:
Ifomu lekhoyili/le-Spool, ukugoqa ngepulasitiki, isikhwama esivalwe nge-vacuum noma ukupakishwa okwenziwe ngokwezifiso uma ucela

Incazelo Yomkhiqizo:

Ucingo lwe-alloy lwe-4J28, olwaziwa nangokuthiUcingo lwe-alloy lwe-Fe-Ni, iyinto ethambile enobuthi futhi evala ingilazi. Njengoba inesakhiwo esiqukethe insimbi kanye ne-nickel engaba ngu-28%, inikeza ukufana okuvelele kokushisa nengilazi ye-borosilicate, okwenza isetshenziswe kabanzi ekupakisheni kwe-elekthronikhi kanye nokufakwa kwengilazi kuya kwensimbi.

Intambo engu-4J28ikhombisa izakhiwo ezinhle kakhulu zokuvala, ukusebenza okuzinzile kwamagnetic, kanye nezici zomshini ezithembekile. Isetshenziswa kakhulu kumashubhu kagesi, ekupakishweni kwe-hermetic, ezindlini ze-semiconductor, kanye nasezindiza ezinokwethenjelwa kakhulu kanye nezingxenye zempi.

Izici:

• Ukuvalwa Okuhle Kakhulu Kwengilazi Kuya Ensimbini: Ukuhambisana okuhle kokukhulisa ukushisa nengilazi ye-borosilicate yezivalo eziqinile, ezivalekile

• Izakhiwo Ezinhle ZikaMagnetic: Kufanelekela izinhlelo zokusebenza ezithambile zikamagnetic kanye nempendulo eqinile yamagnetic

• Ukunemba Okuphezulu: Kutholakala ngobubanzi obuncane kakhulu, kudwetshwe ngokunemba kwezingxenye ze-elekthronikhi ezizwelayo

• Ukumelana ne-Oxidation: Ubuso obukhanyayo, obungena-oxidation, obufanele ukuvalwa kwe-vacuum kanye nokwethenjwa okuphezulu

• Okungenziwa ngokwezifiso: Ubukhulu, ukupakishwa, kanye nezimo zobuso kungalungiswa ngokwezidingo zamakhasimende athile

Izicelo:

• Amashubhu kagesi kanye namadivayisi okuhlanza umoya

• Ama-relay nama-sensor avaliwe kusuka kungilazi kuya kunsimbi

• Amaphakheji e-semiconductor kanye ne-hermetic

• Izingxenye ze-elekthronikhi zezindiza kanye nezezinga lezempi

• Izingxenye ze-optical neze-microwave ezidinga ukufana okuqondile kokukhula kokushisa
