Alloy-4J29 sikuti amangokhala ndi kuwonjezereka kwa kutentha kofanana ndi galasi, koma mawonekedwe ake osasunthika owonjezera kutentha amatha kupangidwa kuti agwirizane ndi galasi, motero amalola kuti mgwirizanowo ukhale wosiyana ndi kutentha kwakukulu. Mwachilengedwe, imalumikizana ndi galasi kudzera pagawo lapakati la nickel oxide ndi cobalt oxide; gawo la chitsulo okusayidi ndilotsika chifukwa cha kuchepa kwake ndi cobalt. Mphamvu ya mgwirizano imadalira kwambiri makulidwe a oxide wosanjikiza ndi mawonekedwe. Kukhalapo kwa cobalt kumapangitsa kuti oxide wosanjikiza ikhale yosavuta kusungunuka ndi kusungunuka mu galasi losungunuka. Mtundu wa imvi, imvi-buluu kapena imvi-bulauni umasonyeza chisindikizo chabwino. Mtundu wachitsulo umasonyeza kusowa kwa okusayidi, pamene mtundu wakuda umasonyeza chitsulo chochuluka kwambiri cha okosijeni, nthawi zonse zomwe zimatsogolera ku mgwirizano wofooka.
Ntchito:Amagwiritsidwa ntchito kwambiri pazigawo za vacuum yamagetsi ndi kuwongolera mpweya, chubu chodzidzimutsa, chubu choyatsira, maginito agalasi, ma transistors, pulagi yosindikizira, ma relay, kutsogolera mabwalo ophatikizika, chassis, bulaketi ndi kusindikiza kwina kwanyumba.
