Zinc ke eona ntho e ka sehloohong ea alloying bakeng sa letoto lena, 'me ha magnesium e eketsoa ka tekanyo e nyane, sephetho ke motsoako o ka phekolehang mocheso, o matla haholo.Lintho tse ling tse kang koporo le chromium le tsona li ka kenyelletsoa ka bongata bo fokolang.Li-alloys tse tsebahalang haholo ke 7050 le 7075, tse sebelisoang haholo indastering ea lifofane.
Li-Alloys tse sa Phekoleheng ka Mocheso
Li-alloys tse se nang mocheso li matlafatsoa ka ho sebetsa ka serame.Ts'ebetso e batang e etsahala nakong ea mekhoa ea ho roala kapa ea ho qhekella 'me ke ketso ea ho "sebetsa" tšepe ho etsa hore e be matla.Ka mohlala, ha o theolela aluminium ho ea ho li-gauge tse tšesaane, e ba matla.Sena ke hobane ho sebetsa ho batang ho haha likheo le likheo ka har'a sebopeho, e leng se thibelang ho tsamaea ha liathomo tse amanang le tse ling.Sena se eketsa matla a tšepe.Lintho tsa alloying tse kang magnesium li matlafatsa phello ena, e bakang matla a phahameng le ho feta.

Manganese ke karolo e kholo ea motsoako letotong lena, hangata e nang le magnesium e nyane.Leha ho le joalo, ke karolo e lekanyelitsoeng feela ea manganese e ka kenyelletsoang aluminium ka katleho.3003 ke motsoako o tsebahalang bakeng sa morero o akaretsang hobane o na le matla a leka-lekaneng le ts'ebetso e ntle, 'me e ka sebelisoa lits'ebetsong tse kang lisebelisoa tsa mocheso le lisebelisoa tsa ho pheha.Alloy 3004 le liphetoho tsa eona li sebelisoa 'meleng ea makotikoti a seno a aluminium.
4xxx Letoto
Li-alloys tsa 4xxx li kopantsoe le silicon, e ka ekeletsoang ka bongata bo lekaneng ho theola ntlha e qhibilihang ea aluminium, ntle le ho hlahisa brittleness.Ka lebaka lena, letoto la 4xxx le hlahisa terata e ntle haholo ea ho tjheseletsa le li-alloys tsa brazing moo ho hlokahalang sebaka se tlase sa ho qhibiliha.Alloy 4043 ke e 'ngoe ea li-alloys tse sebelisoang haholo ho fetisisa bakeng sa li-alloys tsa welding 6xxx bakeng sa lits'ebetso tsa meralo le tsa likoloi.
