I-aluminiyam ipleyiti idla ngokwahlulahlulwe kwezi ntlobo zimbini zilandelayo:
1. Ngokokwakheka kwe-alloy:
Iphepha eliphezulu le-aluminiyam ecocekileyo (iqengqeleke ukusuka kwi-aluminium yococeko ephezulu enomxholo ongaphezulu kwe-99.9)
Ipleyiti yealuminiyam ecocekileyo (eyenziwe ngealuminiyam esulungekileyo eqengqelekayo)
I-alloy aluminium ipleyiti (eyenziwe nge-aluminiyam kunye ne-alloys encedisayo, ngokuqhelekileyo i-aluminium yobhedu, i-aluminium manganese, i-silicon ye-aluminium, i-aluminium magnesium, njl.
Ipleyiti yealuminiyam ehlanganisiweyo okanye ipleyiti yebrazed (injongo eyodwa ye-aluminiyam ipleyiti imathiriyeli efunyenwe ngokudibanisa izinto ezininzi)
I-aluminiyam enecwecwe le-aluminiyam (iphepha le-aluminiyam eliqatywe ngephepha elicekethekileyo le-aluminiyam ngeenjongo ezikhethekileyo)
2. Ukwahlulwe ngobungqimbaiyunithi mm)
iphepha le-aluminium (iphepha le-aluminium) 0.15-2.0
Ipleyiti eqhelekileyo (iphepha le-aluminium) 2.0-6.0
Ipleyiti ephakathi (ipleyiti ye-aluminium) 6.0-25.0
Ipleyiti etyebileyo (ipleyiti yealuminiyam) 25-200 ipleyiti etyebileyo engaphezulu kwama-200
