Ingcaciso yeMveliso:

I-4J28 i-alloy wire, eyaziwa ngokubaI-Fe-Ni i-alloy wire, yinto echanekileyo yemagnethi ethambileyo kunye neglasi yokutywina. Ngokwakheka okubandakanya intsimbi kunye ne-nickel ye-28%, ibonelela ngokuhambelana nokwandiswa kwe-thermal ngeglasi ye-borosilicate, iyenza isetyenziswe ngokubanzi kwipakethe ye-elektroniki kunye ne-glass-to-metal izicelo zokutywinwa.

4J28 ucingoibonisa iimpawu ezigqwesileyo zokutywina, ukusebenza kwemagnethi okuzinzileyo, kunye neempawu ezithembekileyo zoomatshini. Isetyenziswa kakhulu kwiityhubhu ze-elektroniki, ukupakishwa kwe-hermetic, izindlu ze-semiconductor, kunye nokuthembeka okuphezulu kwe-aerospace kunye nezixhobo zomkhosi.

Iimbonakalo:

• Ukutywinwa okugqwesileyo kweglasi ukuya kwintsimbi: Ukwandiswa kwe-thermal efanelekileyo ehambelanayo kunye neglasi ye-borosilicate yokutywinwa, izitywini ze-hermetic

• IiPropathi eziLungileyo zeMagnetic: Ilungele ukusetyenziswa kwemagnethi ethambileyo kunye nempendulo yemagnethi ezinzileyo

• Ukuchaneka okuPhakamileyo koMda: Ifumaneka kwiidayamitha ezicolekileyo kakhulu, ngokuchanekileyo ezotywe kumacandelo abuthathaka e-elektroniki.

• Ukumelana ne-Oxidation: Umphezulu oqaqambileyo, awunayo i-oxidation, ilungele ivacuum kunye nokutywinwa okuphezulu kokuthembeka.

• Ukwenziwa ngokwezifiso: Imilinganiselo, ukupakishwa, kunye neemeko zomphezulu zinokulungelelaniswa neemfuno ezithile zabathengi

Usetyenziso:

• Iityhubhu ze-elektroniki kunye nezixhobo zokufunxa

• Iglasi ukuya kwintsimbi etywiniweyo iireyilayi kunye nezinzwa

• Iiphakheji ze-Semiconductor kunye ne-hermetic

• I-aerospace kunye nezixhobo ze-elektroniki zodidi lomkhosi

• Amalungu e-Optical kunye ne-microwave afuna ukuhambelana okuthe ngqo kwe-thermal
