Urukurikirane 4000 muri rusange rufite silicon iri hagati ya 4.5% na 6%, kandi nibiri hejuru ya silicon, niko imbaraga nyinshi. Ahantu ho gushonga ni muke, kandi ifite imbaraga zo kurwanya ubushyuhe no kwambara. Ikoreshwa cyane mubikoresho byo kubaka, ibice bya mashini, nibindi.

Urukurikirane 5000, hamwe na magnesium nkibintu nyamukuru, birashobora kandi kwitwa magnesium aluminium. Bikunze kugaragara mu nganda, ifite ubucucike buke, imbaraga zingana cyane, no kuramba neza.

Urukurikirane 6000, hamwe na magnesium na silicon nkibintu nyamukuru, byibanda kubiranga urukurikirane rw'ibice bine hamwe na bitanu, bikwiranye na ssenariyo hamwe na ruswa nyinshi na okiside.

Urukurikirane 7000, ahanini rurimo ibintu bya zinc, narwo ni ibikoresho bya aluminiyumu yindege, birashobora kuvurwa ubushyuhe, ni ibya superhard aluminium, kandi bifite imbaraga zo kwihanganira kwambara.

Urukurikirane 8000, ni sisitemu ivanze itari hejuru yavuzwe haruguru, ni iyindi serie kandi ikoreshwa cyane mubikorwa bya aluminium.
