3203 Aluminum Alloy Plate
3203 aluminum alloy is a 3000-series aluminum alloy: the main alloying addition is manganese, and it is formulated for primary forming into wrought products. 3203 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-3203. Additionally, the UNS number is A93203.
The properties of 3203 aluminum include nine common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 3203 aluminum to: 3000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
