Tolerance Aluminum Sheet

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.

Tolerance aluminum sheet.

Specified width in. 2011 t3 2024 t4 6061 t6 t651 cold finish. 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. Below you will find the tolerances for plates an sheets according to alloy group.

Sheets specified to stretcher leveled standard of flatness exclusive of 1 4 2 3 4 and full hard tem pers of 200 and 300 series grades. Also known as flat stock these sheets and bars are precision ground on the top and bottom. Flatness tolerance thickness width length maximum deviation in in in from a horizontal inches inches inches flat surface in inches 3 16 48 96 1 8 3 16 48 96 1 4 3 16 48. Tight tolerance high strength 2024 aluminum rods.

Sheet metal guage tolerances. Originally developed for aircraft frames uses for 7075 aluminum now include keys gears and other high stress parts. Also known as flat stock these sheets and bars are precision ground on the top and bottom. To help this blog will explain the gauge system and features a sheet metal gauge chart.

Tight tolerance high strength 2024 aluminum sheets and bars. 0 125 to 0 374 0 0015 aluminum. According to en 485 4 2000 alloy group 1. Tight tolerance high strength 2024 aluminum sheets and bars.

Tolerance in. These rods are precision ground and held to a strict straightness tolerance so they re ready for turning in a lathe. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example.

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