ABSTRACT: Insoluble constituents in
3104 alloy for beverage cans manufacturing play an important role in deep
ironing process. This paper studies the effect of Fe content in the alloy on volume
fraction of the constituents Al6(Fe, Mn)3 and Al12(Fe,
Mn)3Si and its influence on ironing die pickup. It is shown that
with Fe content increase, the amount of these constituents rises that helps
prevent tool galling. Trials made at a can plant showed less ironing die
changeovers at bodymakers. The optimum Fe content for aluminum can production
can be considered between 0.47% and 0.53% that corresponds to 2.0% - 2.3% of
insoluble constituent volume fraction. Greater amounts than this cause problems
with excessive constituent particle formation and earing; smaller amounts
result in increased ironing die galling.
