The comprehensive effect of magnesium,silicon and manganese on the property of 6082 aluminum alloy with different ingredients was compared and analyzed through microscopic detection,mechanical detection,grain size detection and bending detection.The elements of magnesium and silicon are combined into Mg2Si in a certain proportion,and a certain amount of silicon is remaining.Owing to the different amounts of magnesium and silicon elements added,Mg2Si and excess silicon have different proportionality relationship,which directly affects the mechanical property and bending property after aging.The function of manganese is mainly to inhibit recrystallization,control grain size,and has an effect on the phenomenon of orange peel after bending.
