Aluminiyamu mkuwa ndi malata mkuwa ndi ma aloyi awiri amkuwa osiyanasiyana omwe amasiyana mbali zambiri. Pano pali kufananitsa mwatsatanetsatane kwa ma alloys awiri:
Mfundo zazikuluzikulu
Aluminiyamu bronze: Aloyi yopangidwa ndi mkuwa yokhala ndi aluminiyamu monga chinthu chachikulu chopangira ma aloyi, ndipo zotayidwa nthawi zambiri sizidutsa 11.5%. Kuphatikiza apo, chitsulo chokwanira, faifi tambala, manganese ndi zinthu zina nthawi zambiri amawonjezeredwa ku mkuwa wa aluminiyamu kuti apititse patsogolo ntchito yake.
Mkuwa wa malata: Mkuwa wokhala ndi malata monga chinthu chachikulu chopangira alloying, zomwe zili ndi malata nthawi zambiri zimakhala pakati pa 3% ndi 14%. Mulingo wa malata wopunduka wamkuwa sapitilira 8%, ndipo nthawi zina phosphorous, lead, zinki ndi zinthu zina zimawonjezeredwa.
Makhalidwe amachitidwe
Aluminium Bronze:
Ili ndi mphamvu zambiri, kuuma komanso kukana kuvala, ndipo ndiyoyenera kupanga zida zamphamvu kwambiri komanso zosavala kwambiri, monga magiya, zomangira, mtedza, ndi zina zambiri.
Ili ndi kukana kwa okosijeni wabwino kwambiri komanso kukana dzimbiri, makamaka mumlengalenga, madzi abwino komanso madzi a m'nyanja.
Mkuwa wa aluminiyamu sutulutsa zonyezimira ndipo ukhoza kugwiritsidwa ntchito kupanga zida zopanda phokoso.
Ili ndi matenthedwe abwino kwambiri komanso kuuma kokhazikika, ndipo ndi yoyenera ngati nkhungu.
Tin bronze:
Ili ndi zida zamakina apamwamba, anti-friction komanso kukana kwa dzimbiri, ndipo ndi yosavuta kudula, imakhala ndi zida zabwino zowotcherera komanso zowotcherera, shrinkage coefficient yaying'ono, ndipo simaginito.
Mkuwa wa malata wokhala ndi phosphorous uli ndi makina abwino ndipo ukhoza kugwiritsidwa ntchito ngati ziwalo zosamva kuvala komanso zotanuka za zida zamakina zolondola kwambiri.
Mkuwa wa malata wokhala ndi lead nthawi zambiri umagwiritsidwa ntchito ngati zigawo zosagwira ntchito komanso ngati ma bere otsetsereka, ndipo mkuwa wa malata wokhala ndi zinki ukhoza kugwiritsidwa ntchito ngati zoponya zotchingira mpweya kwambiri.
Malo ofunsira
Aluminium bronze: Amagwiritsidwa ntchito kwambiri pamakina, zitsulo, kupanga, zakuthambo, ndi zomangamanga, makamaka m'malo omwe amafunikira mphamvu zambiri, kukana kuvala kwambiri, komanso kukana kwa dzimbiri.
Mkuwa wa malata: Chifukwa cha kukana kwake bwino kumenyana ndi kuvala, nthawi zambiri umagwiritsidwa ntchito popanga ma bearings ndi ziwalo zina zomwe zimakhala ndi mikangano, ndipo amagwiritsidwanso ntchito popanga ma valve ndi ziwalo zina zosagwira ntchito.
Kuponya ndi processing
Mkuwa wa aluminiyamu: Ukhoza kutenthedwa ndi kulimbikitsidwa, komanso umakhala ndi mphamvu yabwino pakutentha, koma sikophweka kuumitsa powotcherera.
Mkuwa wa malata: Ndizitsulo zachitsulo zopanda chitsulo zomwe zimakhala ndi shrinkage yaying'ono kwambiri yoponyera, yoyenera kupanga ma castings okhala ndi mawonekedwe ovuta, ma contour omveka bwino, komanso zofunikira zochepetsera mpweya.
Kusamalitsa
Posankha kugwiritsa ntchito mkuwa wa aluminiyamu kapena mkuwa wa malata, chigamulocho chiyenera kukhazikitsidwa pazochitika zomwe zimagwiritsidwa ntchito komanso zofunikira zogwirira ntchito.
Mtengo ndi kupezeka kwa aluminiyamu mkuwa ndi malata amatha kusiyanasiyana kutengera dera komanso kupezeka kwa msika.
Mwachidule, mkuwa wa aluminiyamu ndi mkuwa wa malata uli ndi kusiyana kwakukulu pazinthu zazikulu, mawonekedwe a magwiridwe antchito, malo ogwiritsira ntchito, kuponyera ndi kukonza. Posankha aloyi kuti agwiritse ntchito, mfundo zomwe zili pamwambazi ziyenera kuganiziridwa mozama.
