(Khatiso ea bone: 2A12 aluminium alloy)

Le kajeno, lets'oao la 2A12 e ntse e le motho ea ratehang oa sefofane. E na le matla a phahameng le polasetiki maemong a bobeli a tlhaho le a maiketsetso a botsofali, e leng se etsang hore e sebelisoe haholo ha ho etsoa lifofane. E ka sebetsoa ka lihlahisoa tse felileng, joalo ka lipoleiti tse tšesaane, lipoleiti tse teteaneng, lipoleiti tse fapaneng tse fapaneng, hammoho le mekoallo e fapaneng, li-profiles, liphaephe, forgings le life forgings, jj.

Ho tloha ka 1957, Chaena e atlehile ho hlahisa 2A12 aluminium alloy ka katleho lapeng ho etsa likarolo tse ka sehloohong tse jarang moroalo oa mefuta e fapaneng ea lifofane, joalo ka letlalo, liforeimi tsa karohano, mapheo a maballo, likarolo tsa skeleton, joalo-joalo. E boetse e sebelisoa ho etsa likarolo tse ling tse sa jarang moroalo.

Ka nts'etsopele ea indasteri ea lifofane, lihlahisoa tsa alloy le tsona li ntse li eketseha kamehla. Ka hona, e le ho finyella litlhoko tsa mefuta e mecha ea lifofane, lipoleiti le litlaleho tse boemong ba botsofali ba maiketsetso, hammoho le litlhaloso tse ling tsa lipoleiti tse teteaneng bakeng sa ho imolla khatello ea kelello, li 'nile tsa ntlafatsoa ka katleho le ho kenngoa hore li sebelisoe.
