Pa aluminiyamu, nthawi zambiri pamakhala aluminiyamu yoyera ndi aluminiyamu, kotero pali magulu awiri a aluminiyamu: aluminiyamu yoyera ndi aluminiyamu yoyera.
(1) Aluminiyamu yeniyeni:
Aluminiyamu yoyera imagawidwa m'magulu atatu malinga ndi kuyera kwake: aluminiyamu yoyera kwambiri, aluminiyamu yoyera kwambiri ya mafakitale ndi aluminiyamu yoyera ya mafakitale. Kuwotcherera kumachitika makamaka ndi aluminiyamu yoyera ya mafakitale. Kuyera kwa aluminiyamu yoyera ya mafakitale ndi 99.7%^} 98.8%, ndipo magiredi ake akuphatikizapo L1, L2, L3, L4, L5, ndi L6.
(2) Aloyi ya aluminiyamu
Aloyi ya aluminiyamu imapezeka powonjezera zinthu zosakaniza ku aluminiyamu yoyera. Malinga ndi makhalidwe a zinthu zosakaniza za aluminiyamu, zitha kugawidwa m'magulu awiri: zinthu zosakaniza za aluminiyamu zosinthika ndi zinthu zosakaniza za aluminiyamu zotayidwa. Aloyi ya aluminiyamu yosinthika ili ndi pulasitiki wabwino ndipo ndi yoyenera kukonzedwa ndi kupanikizika.
Mitundu yayikulu ya aluminiyamu ndi iyi: 1024, 2011, 6060, 6063, 6061, 6082, 7075
Aluminiyamu Kalasi
Mndandanda wa 1×× ndi: aluminiyamu yoyera (zochuluka za aluminiyamu sizichepera 99.00%)
Mndandanda wa 2××× ndi: aluminiyamu yokhala ndi mkuwa ngati chinthu chachikulu cha aloyi
Mndandanda wa 3××× ndi: aluminiyamu yokhala ndi manganese ngati chinthu chachikulu chopangira alloying
Mndandanda wa 4××× ndi: aluminiyamu yokhala ndi silicon ngati chinthu chachikulu chopangira alloying
Mndandanda wa 5××× ndi: aluminiyamu yokhala ndi magnesium ngati chinthu chachikulu chopangira alloy
Mndandanda wa 6××× ndi: aluminiyamu yokhala ndi magnesium ngati chinthu chachikulu cha aloyi ndi gawo la Mg2Si ngati gawo lolimbitsa.
Mndandanda wa 7××× ndi: aluminiyamu yokhala ndi zinki ngati chinthu chachikulu cha aloyi
Mndandanda wa 8××× ndi: aluminiyamu yokhala ndi zinthu zina monga zinthu zazikulu zophatikizira
Mndandanda wa 9××× ndi: gulu la alloy lowonjezera
Chilembo chachiwiri cha giredi chimasonyeza kusintha kwa aluminiyamu yoyambirira yoyera kapena aluminiyamu, ndipo manambala awiri omaliza amasonyeza giredi. Manambala awiri omaliza a giredi amafotokoza mitundu yosiyanasiyana ya aluminiyamu yomwe ili mu gulu lomwelo kapena amasonyeza kuyera kwa aluminiyamu.
Manambala awiri omaliza a magiredi 1××× amafotokozedwa motere: kuchuluka kwa aluminiyamu yocheperako. Kalata yachiwiri ya giredi imasonyeza kusintha kwa aluminiyamu yoyambirira yoyera.
Manambala awiri omaliza a magiredi a 2×××～8××× alibe tanthauzo lapadera ndipo amagwiritsidwa ntchito pongosiyanitsa ma alloy osiyanasiyana a aluminiyamu omwe ali mgulu lomwelo. Chilembo chachiwiri cha giredi chimasonyeza kusintha kwa aluminiyamu yoyambirira yoyera.
