Kufotokozera Kwachidule:

Aloyi-4J29 (Aloyi Wokulitsa)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 yomwe imadziwikanso kuti Kovar alloy. idapangidwa kuti ikwaniritse kufunikira kwa chisindikizo chodalirika cha galasi kukhala chitsulo, chomwe chimafunika muzipangizo zamagetsi monga mababu a magetsi, machubu a vacuum, machubu a cathode ray, komanso mu makina a vacuum mu chemistry ndi kafukufuku wina wasayansi. Zitsulo zambiri sizingathe kutseka galasi chifukwa kuchuluka kwa kutentha kwawo sikofanana ndi galasi, kotero pamene cholumikizira chimazizira pambuyo popangidwa, kupsinjika chifukwa cha kuchuluka kwa kukula kwa galasi ndi chitsulo kumapangitsa kuti cholumikiziracho chisweke.

Alloy-4J29 sikuti imangokhala ndi kutentha kofanana ndi galasi, komanso kukwera kwake kosasunthika kwa kutentha nthawi zambiri kumatha kupangidwa kuti kugwirizane ndi galasi, motero kulola cholumikiziracho kupirira kutentha kwakukulu. Mwa mankhwala, chimalumikizana ndi galasi kudzera mu gawo lapakati la oxide la nickel oxide ndi cobalt oxide; gawo la iron oxide ndi lochepa chifukwa cha kuchepa kwake ndi cobalt. Mphamvu ya cholumikiziracho imadalira kwambiri makulidwe ndi mawonekedwe a oxide layer. Kukhalapo kwa cobalt kumapangitsa kuti gawo la oxide lisungunuke mosavuta ndi kusungunuka mu galasi losungunuka. Mtundu wa imvi, imvi-buluu kapena imvi-bulauni umasonyeza chisindikizo chabwino. Mtundu wachitsulo umasonyeza kusowa kwa oxide, pomwe mtundu wakuda umasonyeza chitsulo chosungunuka kwambiri, m'zochitika zonsezi zomwe zimapangitsa kuti cholumikiziracho chikhale chofooka.

Ntchito:Amagwiritsidwa ntchito makamaka mu zida zamagetsi zoyeretsera mpweya ndi zowongolera mpweya, chubu chogwedeza, chubu choyatsira moto, magnetron yagalasi, ma transistors, pulagi yosindikizira, relay, lead ya ma circuits ophatikizidwa, chassis, mabulaketi ndi zina zotsekera nyumba.
