Masitima othamanga kwambiri amawotchedwa ndi aluminiyamu, ndipo njanji zina zothamanga kwambiri zimadutsa m'dera lozizira la madigiri 30 Celsius; zida zina, zida ndi zofunika tsiku lililonse pa sitima Antarctic kafukufuku sayansi ndi zopangidwa aluminiyamu ndipo ayenera kupirira opanda madigiri sikisite-seveni Mayeso Celsius; zida zina za sitima zamalonda zochokera ku China kudzera ku Arctic kupita ku Ulaya zimapangidwanso ndi aluminiyamu, zina zomwe zimawonekera kunja, komanso kutentha kwapakati kumakhalanso opanda madigiri 560 Celsius;

Kodi angagwire ntchito bwinobwino m'malo ozizira chonchi?

Yankho ndiloti 'Palibe vuto, aloyi ya aluminiyamu ndi mankhwala a aluminiyamu ndizowopa kwambiri kuzizira ndi kutentha.

Aluminiyamu ndi zitsulo zotayidwa ndizitsulo zabwino kwambiri zotsika kutentha. Iwo alibe kutentha otsika brittleness. Iwo sali otsika kutentha brittle monga zitsulo wamba ndi faifi tambala aloyi. Mphamvu zawo zimawonjezeka ndi kutentha, koma pulasitiki ndi kulimba zimatsatira. Kutsika kwa kutentha kumachepetsedwa, ndiko kuti, pali brittleness yotsika kwambiri. Komabe, ma aluminiyamu ndi ma aluminiyamu aloyi ndizosiyana kwambiri, ndipo palibe kuwonekera kwa brittleness yotsika kutentha. Onse awo mawotchi katundu kuwonjezeka kwambiri ndi kuchepa kwa kutentha, mosasamala kanthu za zikuchokera zakuthupi, kaya kuponyedwa zotayidwa aloyi kapena kupunduka aloyi zotayidwa, ziribe kanthu Kaya ndi ufa zitsulo aloyi kapena gulu la zinthu; zilibe kanthu ndi momwe zinthu ziliri, kaya zili mu chikhalidwe chokonzekera kapena kutentha kutentha; imakhalanso yodziimira pa ndondomeko yokonzekera ingot, kaya ikugwedezeka ndi ingot kapena mosalekeza kusungunuka ndi kusungunuka. Kugudubuzika kapena kugudubuza mosalekeza; palibe ubale ndi njira yochotsera aluminiyumu, electrolysis, kuchepetsa carbothermal, kutulutsa mankhwala, palibe kutentha kwapansi; palibe kudalira chiyero, kaya ndi 99.50% ~ 99.79% ya ndondomeko ya aluminiyamu yoyera, kapena 99.80% ~ 99.949% aluminiyamu yoyera kwambiri, 99.950% ~ 99.9959% ultra-purity aluminium (Super Purity), 99.999609 kuyera kwambiri 90% , > 99.9990% kopitilira muyeso chiyero zotayidwa, etc. No otsika kutentha brittleness.

Chochititsa chidwi, ena awiri zitsulo kuwala-magnesium ndi titaniyamu-alibe kutentha pang'ono brittleness ngati aluminiyamu.
