For more than 60 years the aluminum association has worked with the industry to develop and maintain technical standards for aluminum production.

Tolerance in.
The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.
Length and width tolerances these tend to be tighter and are now all on the plus side i e.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
Uncontrolled dimensions contain two different categories of tolerances.
Thickness tolerances considerably tighter for alloys 1050a 3103.

To reflect manufacturing difficulty the tolerances for alloys 5251 5083 6082 are now wider than this although still a little tighter than in bs1470.
