Kokubili izinzuzo zokusebenza kwe-aluminium alloy nezinto zobumba, kodwa futhi kugwema ngempumelelo ukushiyeka kokusebenza kwento eyodwa, endizeni, indiza, imikhumbi yasolwandle, ezokuthutha ngojantshi, izimoto ezintsha zamandla kanye nezinye izinkambu zobuchwepheshe obuphezulu zinezinhlobonhlobo zamathemba okufaka isicelo. .


Izici zezinto ezibonakalayo: ukuqina okuqondile okuphezulu, amandla athile aphezulu, ukuzinza okuphezulu kwe-dimensional, i-coefficient ephansi yokwandisa okushisayo, ukumuncwa okuhle kwamagagasi, ukumelana nokugqoka okuphezulu, ukumelana nokugqwala... njll.

    Izinto eziyinhlanganisela ye-aluminium ye-silicon carbide ephakathi nendawo nephezulu esizithathele ekulungiseni umsebenzi wohlobo olusha ongenaso isigaba sokusebenzisana, okugwema ngempumelelo ukushiyeka kokuqina kwezinto eziyinhlanganisela yensimbi yobumba, futhi kuthuthukisa kakhulu ukusebenza kokucubungula kanye nobubanzi bokusetshenziswa kwezinto.

    1. I-aluminium silicon carbide - izingxenye zesakhiwo
    Izingxenye zesakhiwo ezinembayo ezinamandla aphezulu - ezinezici zesisindo esingasindi, ukuqina okuphezulu, ukuzinza kwe-dimensional, ukumelana nokugqokwa nokumelana nokugqwala, esikhundleni se-aluminium alloy, insimbi engagqwali, ingxubevange ye-titanium, esetshenziswa ngokunemba okuphezulu, izingxenye zesakhiwo ezingagugi ezinezidingo eziphikisanayo. .

    Izinzuzo zomkhiqizo: isisindo esilula, ukuqina okuphezulu, ukuzinza okuhle kwe-dimensional, umjikelezo wezinga lokushisa eliphezulu neliphansi akulula ukuwohloka, ungacubungula inkimbinkimbi, isakhiwo esinodonga oluncane, izimbobo zokunemba ezincane, i-whorl


    2. I-aluminium silicon carbide - ingxenye yokushisa ukushisa
    I-Microelectronic cooling substrate/igobolondo: i-aluminium silicon carbide yaziwa njengesizukulwane sesithathu sezinto zokupakisha ze-elekthronikhi ngenxa yezakhiwo zayo ezishisayo ezishisayo, futhi isetshenziswa kabanzi emkhakheni wokupakisha ngogesi (isizukulwane sokuqala njenge-aluminium, ithusi; Isizukulwane sesibili esinjalo njenge-Kewa, i-molybdenum yethusi, ingxube ye-tungsten yethusi .... njll).
