Aluminum association sheet thickness tolerances.

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. For more than 60 years the aluminum association has worked with the industry to develop and maintain technical standards for aluminum production. Mm 48 1 219 in.
