Copper (CU)
Pamene mkuwa (cu) umasungunuka mu aluminiyamu olosera, makinawo amagwira ntchito bwino ndipo kudulira kumakhala bwino. Komabe, kukana kwa chimbudzi kumachepa ndipo kupindika kotentha kumachitika. Mkuwa (cu) monga kudetsa kumachitikanso chimodzimodzi.
Mphamvu ndi kuuma kwa zitsulo zitha kuchulukitsidwa kwambiri ndi mkuwa (cu) zopitilira 1.25%. Komabe, mpweya wa al-ndu umayambitsa shrinkage nthawi ya disk, ndikutsatira ndikukulitsa, komwe kumapangitsa kukula kwa kutulutsa kosakhazikika.
Magnesium (mg)
Kuchulukitsa kwa magnesium (mg) kumawonjezeredwa kupondereza kutumphuka. Pamene magnesium (mg) pomwe zopitilira mtengo, madzimadzi akuwonongeka, komanso kubisalamo ndi mphamvu zakumaso kumachepetsedwa.
Silicon (SI)
Silicon (SI) ndiye gawo lalikulu la kukonzanso madzi. Madzi abwino kwambiri amatha ku etectic kupita ku hyperctic. Komabe, silican (si) kuti ma crystallis amatenga mfundo zolimba, kupangitsa kuti muzichepetsa kuthamanga. Chifukwa chake, nthawi zambiri siziloledwa kupitilira mawu a eutectic. Kuphatikiza apo, silicon (SI) kumatha kusintha nyonga, kuuma, kudula magwiridwe antchito, ndi mphamvu pa kutentha kwambiri kwinaku ndikuchepetsa.
Magnesium (mg) aluminium-magnesium alloy ali ndi vuto labwino kwambiri. Chifukwa chake, ADC5 ndi ADC6 ndi omwe amagwiritsa ntchito zosokoneza. Mitundu yake yolimba ndi yayikulu kwambiri, motero ili ndi maluwa otentha, ndipo zokhumudwitsa zimakonda kusokonekera, kupangitsa kuti kuvutitsa. Magnesium (mg) ngati zodetsa ku zigawo za al-CA-s, mg2si ipangitsa kuti musinthe, kotero muyezo nthawi zambiri umakhala mkati mwa 0.3%.
Chitsulo (Fe) Ngakhale chitsulo (Fe) imatha kuwonjezera kutentha kwa zinc (ZN) ndikuchepetsa machubu achitsulo, kachitsulo (kuwononga) kusungunuka, ndikusungunuka mu zinc (ZN). Chitsulo (chomenyedwa ndi aluminiyam (al) ndi chocheperako, ndipo chitsulo (cha chitsulo (cha) chimapitilira malire, chidzalira monga Feal3. Zofooka zomwe zimayambitsidwa ndi ma boti nthawi zambiri amapanga slag ndikuyandama monga Feal3 mankhwala. Kuponyera kumakhala kukhazikika, ndipo makina amalima olima. Madzi a chitsulo amakhudza kusalala kwa kuponyera.
Zosayipa zachitsulo (Fe) zimatulutsa singano ngati zaseri za Feal3. Popeza kuwononga kwamwalira kumakhazikika mwachangu, makhiristo okhalamo ali bwino ndipo sangawonekere zigawo zovulaza. Ngati zomwe zili ndi zosakwana 0.7%, sizovuta kuzilamulira, motero zitsulo za 0,8-1.0% ndibwino kuti muwonongeke. Ngati pali chitsulo chachikulu (Fe), zitsulo zopangidwa ndi ziphuphu zidzapangidwa, ndikupanga mfundo zovuta. Komanso, zitsulo (zopangidwa) zopitilira 1.2%, zimachepetsa mphamvu ya alloy, kuwononga mtundu wa kuponyedwa, ndikufupikitsa moyo wa zitsulo zida zowonongeka.
Nickel (NI) ngati mkuwa (cu), pali chizolowezi chowonjezera mphamvu yakuwonongera komanso kuuma, ndipo chimakhala ndi mphamvu yolimbana ndi kutupa. Nthawi zina, nickel (ni) amawonjezeredwa kukonza mphamvu zotentha kwambiri komanso kukana kwa kutentha, koma zimakhala ndi vuto pakukana kutukuka komanso kuchititsa thupi.
Manganese (Mn) amatha kusintha kulimba kwa kutentha kwambiri kwa owongolera omwe ali ndi mkuwa (cu) ndi silicon (s). Ngati ipitilira malire ena, ndizosavuta kutulutsa al-si-fe-f-t * t h; Manganese (Mn) amatha kuletsa kukonzanso kwa aluminiyam emosys, kuwonjezera kutentha kutentha, ndikukonzanso mbewu zobwezerezedwa kwambiri. Kukonzanso kwa mbewu zobwerezabwereza kumachitika makamaka chifukwa cholepheretsa mphamvu ya mththrind pa kukula kwa mbewu zobwezerezedwanso. Ntchito ina ya mthth6 ndikutha kupatsirana chitsulo (Fe) kupanga (Fe, MN) ndikuchepetsa zoyipa zachitsulo. Manganese (Mn) ndi chinthu chofunikira kwambiri cha aluminiyamu exres ndipo amatha kuwonjezeredwa ngati Al-MN Branalone Alloy kapena limodzi ndi zinthu zina zopambana. Chifukwa chake, ma aluminiyamu ambiri amakhala ndi manganese (Mn).
Zinki (zn)
Ngati zinc (ZN) ilipo, imawonetsa kutentha kwamantha. Komabe, akaphatikizidwa ndi mercury (hg) kuti apange algzn2 ords, zimabweretsa mphamvu yolimbikitsa. Jis imalepheretsa kuti zomwe zili ndi zinc (ZN) ziyenera kukhala zosakwana 1.0%, pomwe mfundo zachilendo zimatha kulola mpaka 3%. Kukambirana kumeneku sikutanthauza ku zinki (zn) ngati gawo la alloy koma gawo lake monga kudetsa ming'alu yopumira.
Chromium (CR)
Chromium (cr) amapanga zigawo zingapo monga (crfe) Al7 ndi (Cran) Al12 mu Aluminiyamu, kulepheretsa Nuckinirization ndi kukula kwa zolimbitsa thupi. Zimathandizanso kulimbitsa mphamvu kwa iloy ndikuchepetsa kupsinjika kusokoneza chidwi. Komabe, imatha kuwonjezera kukhudzika.
Titanium (ti)
Ngakhale titanium yaying'ono (ti) mu entoy imatha kusintha zinthu zake zamakina, koma zitha kuchepetsanso mawonekedwe ake. Zolemba za Titanium (ti) mu mndandanda wa al-ti) zopindika za mpweya wabwino pafupifupi 0.15%, ndipo kupezeka kwake kumatha kuchepetsedwa ndi kuwonjezera kwa Boron.
Atsogolera (PB), CAN (SN), ndi Cadmium (CD)
Calcium (CA), kutsogolera (PB), tini (sn), ndipo zodetsa zina zitha kukhalapo mu aluminiyamu olosera. Popeza zinthuzi zimakhala ndi mfundo zosiyanasiyana zosungunuka, zimapanga mitundu yosiyanasiyana ndi aluminiyamu (al), zomwe zimapangitsa kuti zikhale zovuta pazinthu za aluminiyam. Calcium (CA) ili ndi solubility yolimba kwambiri mu aluminiyamu ndikupanga caal4 mankhwala ndi aluminium (al), omwe amatha kusintha magwiridwe antchito a aluminiyamu. Kutsogolera (PB) ndi Tini (SN) ndi zitsulo zosungunuka zokhala ndi solubility yotsika mu aluminiyamu (al), omwe amatha kuchepetsa mphamvu ya alloy koma amayendetsa.
Kuchulukitsa kutsogolera (PB) kumatha kuchepetsa kuuma kwa zinki (ZN) ndikuwonjezera kusungunuka kwake. Komabe, ngati aliyense wa kutsogolera (PB), tini (sn), kapena cadmium (cd) imaposa kuchuluka kwa aluminiyamu: zinc.y zitha kuchitika. Trossion iyi imakhala yosagwirizana, imachitika patatha nthawi inayake, ndipo imatchulidwa makamaka pansi pa kutentha kwambiri, minofu yotentha kwambiri.
