Thickness Tolerances Of Aluminum Alloys 1100, 3003, & 5005



The table below shows the thickness tolerances of alloys for various specified thicknesses and widths.  It applies to alloys 1100, 3003, and 5005 as well as to alloys 1060, 1350, 3005, 3105, 5050, and 5457.

The same tolerances apply to 1100 and 3003 alloy clad reflector sheet, and to alclad variations of all alloys.

The data are based on standards developed by the Aluminum Association and ANSI.
