Ingcaciso yeMveliso:

Ucingo lwe-alloy lwe-4J28, olukwaziwa ngokubaUcingo lwe-alloy ye-Fe-Ni, sisixhobo esithambileyo esinobunewunewu kunye nesitywina seglasi. Ngomxube oqulethwe yintsimbi kunye ne-nickel emalunga ne-28%, inika ukuhambelana okugqwesileyo kobushushu kunye neglasi ye-borosilicate, okwenza ukuba isetyenziswe kakhulu kwiipakethe ze-elektroniki kunye nokusetyenziswa kokuvala iglasi ukuya kwisinyithi.

Ucingo lwe-4J28Ibonisa iimpawu zokutywina ezibalaseleyo, ukusebenza okuzinzileyo kwemagnethi, kunye neempawu zoomatshini ezinokuthenjwa. Isetyenziswa kakhulu kwiityhubhu ze-elektroniki, ukupakisha okungenamoya, izindlu ze-semiconductor, kunye nezixhobo zeenqwelo-moya kunye nezomkhosi ezithembeke kakhulu.

Iimbonakalo:

• Ukutywina okuGlass-to-Metal okuGlass: Ukuhambelana okufanelekileyo kokwandiswa kobushushu kunye neglasi ye-borosilicate kwiitywina eziqinileyo nezingenamoya

• Iipropati ezilungileyo zeMagnetic: Ifanelekile kwizicelo zemagnethi ezithambileyo kunye nempendulo yemagnethi ezinzileyo

• Ubungakanani obuphezulu bokuchaneka: Ifumaneka ngobubanzi obucolekileyo kakhulu, itsalwe ngokuchanekileyo kwiindawo ze-elektroniki ezinobuthathaka

• Ukumelana ne-Oxidation: Umphezulu oqaqambileyo, ongena-oxidation, ofanelekileyo kwi-vacuum kunye nokutywinwa okuthembekileyo okuphezulu

• Inokulungiselelwa: Ubukhulu, ukupakisha, kunye neemeko zomphezulu zinokulungiswa ngokweemfuno zabathengi ezithile

Izicelo:

• Iityhubhu ze-elektroniki kunye nezixhobo zokucoca umoya
