Vanadium ikora VAl11 ivangavanga muri aluminiyumu, igira uruhare mukutunganya ibinyampeke mugikorwa cyo gushonga no guta, ariko ingaruka ni nto ugereranije na titanium na zirconium. Vanadium nayo ifite ingaruka zo gutunganya imiterere ya rerystallisation no kongera ubushyuhe bwa rerystallisation.
Gukomera gukomeye kwa calcium muri aluminiyumu ni bike cyane, kandi ikora ibice bya CaAl4 hamwe na aluminium. Kalisiyumu nayo ni ibintu birenze urugero bya aluminiyumu. Aluminiyumu hamwe na calcium ya 5% na manganese 5% ifite superplasticity. Kalisiyumu na silicon bigize CaSi, idashobora gushonga muri aluminium. Kubera ko ingano yumuti ukomeye wa silicon yagabanutse, ubwikorezi bwa aluminiyumu yinganda zirashobora kunozwa gato. Kalisiyumu irashobora kunoza imikorere yo gukata aluminium. CaSi2 ntishobora gushimangira uburyo bwo kuvura ubushyuhe bwa aluminium. Kurikirana calcium ni byiza gukuramo hydrogen muri aluminiyumu yashongeshejwe.
Kurongora, amabati, na bismuth nibintu bishonga bike. Bafite imbaraga nke zo gukomera muri aluminiyumu, igabanya gato imbaraga za alloy, ariko irashobora kunoza imikorere yo guca. Bismuth yaguka mugihe cyo gukomera, ifasha kugaburira. Ongeramo bismuth kumyunyu ngugu ya magnesium irashobora kwirinda "sodium brittleness".
Antimony ikoreshwa cyane cyane muguhindura ibishishwa bya aluminiyumu, kandi ntibikunze gukoreshwa mububiko bwa aluminiyumu. Gusa gusimbuza bismuth muri Al-Mg yakoze aluminiyumu kugirango wirinde kwinjiza sodium. Iyo ibintu birwanya antimoni byongewe kuri Al-Zn-Mg-Cu ibinyobwa bimwe na bimwe, imikorere yo gukanda bishyushye hamwe no gukonjesha birashobora kunozwa.
Beryllium irashobora kunoza imiterere ya firime ya okiside ikozwe muri aluminiyumu ikozwe kandi ikagabanya igihombo cyo gutwika hamwe nibindi mugihe cyo gutera. Beryllium nikintu cyuburozi gishobora gutera uburozi bwa allergique. Kubwibyo, amavuta ya aluminiyumu ahura nibiryo n'ibinyobwa ntashobora kubamo beryllium. Ibiri muri beryllium mubikoresho byo gusudira mubisanzwe bigenzurwa munsi ya 8μg / ml. Aluminiyumu ikoreshwa nka base yo gusudira nayo igomba kugenzura ibiri muri beryllium.
Sodium hafi ya yose idashobora gushonga muri aluminium, ibishobora gukomera cyane biri munsi ya 0.0025%, kandi aho gushonga kwa sodium biri hasi (97.8 ° C). Iyo sodium ibaho muri alloy, iba yamamajwe hejuru ya dendrite cyangwa imbibi zimbuto mugihe cyo gukomera. Mugihe cyo gutunganya amashyuza, sodium kumupaka wibinyampeke ikora urwego rwamazi ya adsorption, kandi mugihe habaye gucikamo ibice, uruganda rwa NaAlSi rubaho, nta sodium yubusa ibaho, kandi "sodium brittleness" ntabwo ibaho. Iyo ibinini bya magnesium birenze 2%, magnesium izafata silikoni kandi igwe sodium yubusa, bikavamo "sodium embrittlement". Kubwibyo, aluminium nyinshi ya aluminiyumu ntabwo yemerewe gukoresha umunyu wa sodium. Uburyo bwo gukumira "sodium embrittlement" nuburyo bwa chlorination, butuma sodium ikora NaCl ikayirekura muri slag, ikongeramo bismuth kugirango ikore Na2Bi hanyuma yinjire muri matrix; kongeramo antimoni yo gukora Na3Sb cyangwa kongeramo isi idasanzwe nabyo bishobora kugira uruhare rumwe.
