Aluminum 1100-O
Categories: Metal; Nonferrous Metal; Aluminum Alloy; 1000 Series Aluminum
Material Notes: This is a common commercial grade sold when 'aluminum' is specified. As with other unalloyed aluminum grades, it is used where the intrinsic formability and corrosion resistance of aluminum is needed while high strength is not. Example applications include chemical and food handling, sheet metal, hollowware, heat exchangers, and lighting.

Data points with the AA note have been provided by the Aluminum Association, Inc. and are NOT FOR DESIGN.

Composition Notes:
The aluminum content for unalloyed aluminum not made by a refining process is the difference between 100.00 percent and the sum of all other analyzed metallic elements present in amounts of 0.010 percent of more each, expressed to the second decimal before determining the sum. For alloys and unalloyed aluminum not made by a refining process, when the specified maximum limit is 0.XX, an observed value or a calculated value greater than 0.005 but less than 0.010% is rounded off and shown as " less than 0.01%".
Composition information provided by the Aluminum Association and is not for design.
