Uluhlu lwe-4000 ngokubanzi lunomxholo we-silicon phakathi kwe-4.5% kunye ne-6%, kwaye uphezulu umxholo we-silicon, amandla aphezulu. Indawo yayo yokunyibilika iphantsi, kwaye inokumelana nobushushu obuhle kunye nokumelana nokunxiba. Isetyenziselwa ikakhulu kwizinto zokwakha, iinxalenye zoomatshini, njl.

Uthotho lwe-5000, kunye ne-magnesium njengeyona nto iphambili, inokubizwa ngokuba yi-magnesium aluminium alloy. Iqhele ukubonwa kushishino, inoxinano oluphantsi, amandla aphezulu okuqina, kunye nobude obuhle.

Uchungechunge lwe-6000, kunye ne-magnesium kunye ne-silicon njengezona zinto ziphambili, zigxininise iimpawu zechungechunge ezine kunye nochungechunge oluhlanu, olulungele iimeko ezinokonakala okuphezulu kunye ne-oxidation.

Uthotho lwe-7000, ubukhulu becala luqulathe i-zinc element, ikwayeyesixhobo se-aviation ye-aviation, inokunyangwa ubushushu, yeye-superhard aluminium alloy, kwaye inokumelana nokunxiba kakuhle.

I-8000 series, eyinkqubo ye-alloy ngaphandle kokungasentla, yeyabanye uthotho kwaye isetyenziselwa ukuveliswa kwe-aluminium foil.
