Isethulo somkhiqizo:
Amapayipi e-aluminium ahlukaniswe ikakhulukazi abe yizinhlobo ezilandelayo.
Ngokusho komumo: ipayipi eliyisikwele, ipayipi eliyindilinga, ipayipi lephethini, ipayipi elimise okukhethekile, ipayipi le-aluminium yomhlaba wonke.
Ngokwendlela ye-extrusion: ipayipi le-aluminium elingenamthungo kanye nepayipi elivamile le-extrusion.
Ngokuvumelana nokunemba: ipayipi elivamile le-aluminium kanye nepayipi elinembayo le-aluminium, lapho ipayipi elinembayo le-aluminium ngokuvamile lidinga ukucutshungulwa kabusha ngemva kokukhishwa, njengokudweba okubandayo, ukugoqa.
Ngokushuba: ipayipi elivamile le-aluminium kanye nepayipi le-aluminium elincanyana.
Ukusebenza: ukumelana nokugqwala, isisindo esincane.
