Momwe mungasankhire zoyenera pazinthu zawo za aluminiyamu aloyi, kusankha kwa mtundu wa aloyi ndi gawo lofunikira, mtundu uliwonse wa aloyi uli ndi mawonekedwe ake ogwirizana ndi mankhwala, zinthu zina zowonjezera zimatsimikizira mawonekedwe amakina a aluminium alloy conductivity corrosion resistance ndi zina zotero.

Aliyense zotayidwa aloyi mtundu angapeze ake lolingana mankhwala zikuchokera mu GB / T3190-2020.Line 1 ali mkulu zofewa madutsidwe elongation,2 mndandanda ali kuuma mkulu ntchito zabwino kuwotcherera, 3 mndandanda ali ndi ntchito zabwino odana dzimbiri, elongation wabwino, 4 mndandanda ndi otsika malo osungunuka amagwiritsidwa ntchito kwambiri pakuwotcherera, 5 mndandanda wa aloyi wogawa chiŵerengero cha kusiyana ndi chachikulu, 6 mndandanda wa mphamvu ndizovuta, zotsika mtengo, zogwiritsira ntchito msika zimakhala zovuta kwambiri, 7 mndandanda wa ntchito zowotcherera kwambiri ndizofala, choncho kawirikawiri amagwiritsidwa ntchito mbali zamphamvu kwambiri,Pakali pano, ntchito zamsika za mndandanda wa 8 zimayang'ana kwambiri zinthu zopangidwa ndi aluminiyamu.
