Igama Lomkhiqizo:
I-Glass-Sealing Alloy Wire 4J28 | I-Fe-Ni Alloy Wire | I-Soft Magnetic Material

Okubalulekile:
I-4J28 (Fe-Ni Alloy, i-Kovar-type Glass-Sealing Alloy)

Imininingwane:
Itholakala ngamadayamitha ahlukahlukene (0.02 mm ukuya ku-3.0 mm), ubude obungenziwa ngendlela oyifisayo

Izicelo:
Ukuvala ingilazi kuya kwensimbi, amashubhu kagesi, izinzwa, izingxenye zevacuum, nezinye izinto zikagesi ezinembayo

Ukwelashwa kwendawo:
Indawo ekhanyayo, engenayo i-oxide, i-annealed noma idonswa ngokubanda

Ukupakishwa:
Ifomu lekhoyili/i-Spool, ukugoqa ipulasitiki, isikhwama esivalwe ngevacuum noma ukupakisha okwenziwe ngokwezifiso uma ucelwa

Incazelo Yomkhiqizo:

I-4J28 alloy wire, eyaziwa nangokuthiI-Fe-Ni i-alloy wire, iwukuzibuthe okunembayo okunembayo nokuvala ingilazi. Ngokwakheka okuhlanganisa ikakhulukazi i-iron kanye ne-nickel ecishe ibe ngu-28%, inikeza ukunwetshwa okushisayo okuhlukile okuhambisana nengilazi ye-borosilicate, okuyenza isetshenziswe kabanzi ekufakweni kwe-elekthronikhi nasekufakweni uphawu kwengilazi kuya kwensimbi.

4j28 intamboikhombisa izakhiwo ezinhle kakhulu zokuvala, ukusebenza kazibuthe okuzinzile, nezici zemishini ezinokwethenjelwa. Isetshenziswa kakhulu kumashubhu e-elekthronikhi, ukupakishwa kwe-hermetic, izindlu ze-semiconductor, kanye ne-aerospace enokwethenjelwa okuphezulu kanye nezingxenye zempi.

Izici:

• Ukutywinwa Okuhle Kakhulu Kwe-Glass-to-Metal: Ukuhambisana okufanelekile kokunwetshwa okushisayo nengilazi ye-borosilicate yezigxivizo eziqinile, ezi-hermetic

• Izakhiwo Zizibuthe Ezinhle: Ifanele izinhlelo zokusebenza ezithambile zikazibuthe kanye nokuphendula kazibuthe okuzinzile

• Ukunemba Okuphezulu Okuphezulu: Kutholakala ngamadayamitha amahle kakhulu, adwetshwa ngokunemba ezingxenyeni ze-elekthronikhi ezibucayi

• I-Oxidation Resistance: Indawo ekhanyayo, ayinayo i-oxidation, ilungele i-vacuum nokubekwa uphawu okuthembeke kakhulu.

• Okungenziwa ngendlela oyifisayo: Ubukhulu, ukupakishwa, nezimo ezingaphezulu kungalungiselelwa izidingo ezithile zekhasimende

Izicelo:

• Amashubhu e-elekthronikhi namadivayisi we-vacuum

• I-Glass-to-metal sealed relays nezinzwa

• Amaphakheji we-semiconductor kanye ne-hermetic

• I-Aerospace kanye nezingxenye ze-elekthronikhi ezisezingeni lezempi

• Izingxenye ze-Optical ne-microwave ezidinga ukufaniswa okunembayo kokunwetshwa kokushisa
