4000 Series Aluminiyamu Plate Mapepala-Al-Si Aloyi

4000 mndandanda aluminiyamu pepala: woimira 4A01.Ma mbale 4000 a aluminiyamu amtundu wa mndandanda wokhala ndi ma silicon apamwamba kwambiri.Nthawi zambiri silicon zili pakati pa 4.5-6.0%.Ndi ya zida zomangira, zida zamakina, zida zopangira, zida zowotcherera;Malo otsika osungunuka, kukana kwabwino kwa dzimbiri Kufotokozera kwazinthu: Ili ndi mawonekedwe okana kutentha komanso kukana kuvala.

4000 mndandanda wa aluminiyamu aloyi ndi zotayidwa zotayidwa ndi silicon monga chinthu chachikulu alloying.Zambiri mwazitsulo zake zimakhala zotayidwa ndi kutentha zomwe sizinalimbitsidwe ndi aluminiyumu.Ma alloys okha omwe ali ndi Cu, Mg ndi Ni, komanso ma alloys omwe amalimbikitsidwa ndi kuwotcherera kutentha, amatha kuyamwa zinthu zina.Ikhoza kulimbikitsidwa ndi chithandizo cha kutentha.Chifukwa cha kuchuluka kwa silicon, malo otsika osungunuka, kusungunuka kwabwino, kudyetsa kosavuta komanso kusakhala ndi brittleness ya chinthu chomaliza, mndandanda wa alloys uwu umagwiritsidwa ntchito makamaka popanga zowonjezera zowotcherera za aluminiyamu monga mbale zowotcherera, ma electrode ndi mawaya.Aloyiyo imakhala ndi kukana kwabwino kovala komanso kutentha kwambiri, ndipo imagwiritsidwanso ntchito popanga ma pistoni ndi mbali zosagwira kutentha.Aloyi yomwe ili ndi pafupifupi 5% ya silicon ndi yakuda-imvi pambuyo pa anodizing ndi utoto.

Poyerekeza ndi 4Y32, 4032 zotayidwa aloyi ali m'munsi aloyi zinthu zili okhutira, koma ali machinability kwambiri ndi apamwamba amakokedwe mphamvu ya 4000 mndandanda aloyi.Kukula kwa gel osakaniza silika ndi ochepera 70μm ndipo amagwiritsidwa ntchito kwambiri popanga ma pistoni ndi zida zina zotentha kwambiri chifukwa cha mawonekedwe ake apadera.

4Y32 aluminiyamu aloyi ali apamwamba zili zinthu aloyi kuposa 4032 mndandanda, ndipo ali ndi mphamvu bwino ndi kuvala kukana.Kukula kwa silicon koyambirira kumayendetsedwa pakati pa 30-40μm.Chifukwa cha mawonekedwe ake apadera, amagwiritsidwa ntchito kwambiri popanga zida zonse ndi magawo omwe amagwiritsidwa ntchito pa kutentha kwakukulu, monga ma air conditioner apagalimoto, zida zotumphukira.
