Chophimbacho chimapangidwa ndi aluminium alloy.
Ubwino wa aluminium alloy:
1. Kuwala ndi kofewa: kachulukidwe ka aluminiyamu ndi pafupifupi gawo limodzi mwa magawo atatu a zitsulo;
2. Mphamvu zabwino: mphamvu yokhazikika ya aluminiyamu yoyera ndi gawo limodzi mwa magawo asanu a zitsulo za carbon low, koma mphamvu zake zidzawonjezeka kwambiri pambuyo pa chithandizo cha kutentha ndi kulimbikitsana kwa alloying;
3. Kukana bwino kwa dzimbiri: chimodzi mwa makhalidwe a aluminiyamu aloyi ndi kuti wandiweyani okusayidi filimu adzapangidwa pamwamba pamene kukhudzana ndi mpweya, amene angalepheretse dzimbiri, choncho amakhala ndi dzimbiri kukana. Ngati "njira yochizira nembanemba ya aluminiyamu" ikugwiritsidwa ntchito, imatha kupewa dzimbiri;
4. Good processability: ntchito extrusion aloyi zotayidwa ndi zabwino, ndi yachiwiri Machining ndi kupinda processing ndi zosavuta;
5. Zosavuta kukonzanso: aluminiyumu imakhala ndi malo otsika osungunuka, kusinthika kosavuta komanso palibe kuipitsidwa panthawi ya zowonongeka, zomwe zimathandiza kuti chilengedwe chitetezeke komanso chikugwirizana ndi ndondomeko ya chitukuko chokhazikika.
