Aluminum Association Sheet Thickness Tolerances

Aluminum plate and sheet 101 producing aluminum plate.

Aluminum association sheet thickness tolerances.

For more than 60 years the aluminum association has worked with the industry to develop and maintain technical standards for aluminum production. Aluminum from 0 008 inches to less than 0 25 inches thick is considered sheet. Up thru 6 6 thru 24 24 thru 60 60 thru 96 over 96 thickness. Length and width tolerances these tend to be tighter and are now all on the plus side i e.

The colder the stronger aluminum plate is used for storage tanks in many industries in part because some aluminum alloys gain strength at supercold temperatures.

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

From designating alloys to answering technical questions to engaging with the academic community the association s standards technology department creates the backbone of a vital communication. Rolling begins with preheated sheet ingots that can weigh more than 20 tons.
