Isishwankathelo seMveliso:
Intambo ye-alloy ye-4J29, eyaziwa ngokuba yi-Fe-Ni-Co sealing alloy okanye intambo yohlobo lweKovar, isetyenziswa kakhulu kwizicelo ezifuna i-glass-to-metal hermetic sealing. Iqulethe malunga ne-29% ye-nickel kunye ne-17% ye-cobalt, enika ulwandiso olulawulwayo lobushushu oluhambelana kakhulu neglasi ye-borosilicate. Oku kuyenza ilungele ukusetyenziswa kwiityhubhu ze-elektroniki, ii-vacuum relay, ii-infrared sensors, kunye nezixhobo ze-aerospace.

Ukwakhiwa kwezinto:

• I-Nickel (Ni): ~29%

• I-Cobalt (iCo): ~17%

• Intsimbi (Fe): Ibhalansi

• Ezinye izinto: ii-trace amounts ze-Mn, i-Si, i-C, njl.

Ukwanda kobushushu (30–300°C):~5.0 x 10⁻⁶ /°C
Uxinano:~8.2 g/cm³
Ukuxhathisa:~0.42 μΩ·m
Tensile strength:≥ 450 MPa
Ukwandiswa:≥ 25%

Ubungakanani obufumanekayo:

• Ububanzi: 0.02 mm – 3.0 mm

• Ubude: kwiispools, iikhoyili, okanye ubude bokusika njengoko kufuneka

• Umphezulu: Ukhanya, uthambile, awuna-oxidation

• Imeko: Itsalwe ngokutsalwa okanye ngokubandayo

Ezona mpawu:

• Ukuhambelana okuhle kakhulu kokwandiswa kobushushu kunye neglasi eqinileyo

• Ilungele ukutywinwa kwe-hermetic kwizicelo ze-elektroniki kunye neenqwelo-moya

• Ukudityaniswa kakuhle kunye nokuchaneka okuphezulu

• Iipropati zemagnethi ezizinzileyo phantsi kweemeko ezahlukeneyo zokusingqongileyo

• Iidayamitha ezenziwe ngokwezifiso kunye neendlela zokupakisha ziyafumaneka

Izicelo eziqhelekileyo:

• Iireyi zomoya kunye neereyi ezitywinwe ngeglasi

• Ukupakishwa kwezixhobo ze-infrared kunye ne-microwave

• Iindlela zokufikelela kwiglasi kunye nezihlanganisi

• Iityhubhu ze-elektroniki kunye nee-sensor leads

• Izixhobo ze-elektroniki ezivalwe nge-hermetic kwi-aerospace nakwi-defense

Ukupakishwa kunye nokuthunyelwa:

• Ifumaneka ngeeplastiki, iikhoyili, okanye iingxowa ezivaliweyo nge-vacuum

• Ukupakisha okuchasene nomhlwa kunye nokungafumi okukhethiweyo

• Ukuthunyelwa kufumaneka ngenqwelo moya, elwandle, okanye ngokukhawuleza

• Ixesha lokuhambisa: Iintsuku zokusebenza eziyi-7–15 kuxhomekeke kubungakanani

Ukuphathwa kunye nokugcinwa:
Gcina kwindawo eyomileyo necocekileyo. Kuphephe ukufuma okanye ukuvezwa ziikhemikhali. Kunokufuneka ukuba ukuphinda uvalwe ngaphambi kokuba uvale ukuqinisekisa ukuba iglasi ibotshelelwe kakuhle.
