3102 Aluminum Alloy Coil
3102 aluminium alloy is aluminium-manganese family (3000 or 3xxx series). It is one of the most pop aluminum in the 3000 series, with at least 97.85% aluminium by weight. Like most other aluminium-manganese alloys, 3102 is a general-purpose alloy with moderate strength, good workability, and good corrosion resistance. Being lightly alloyed, it tends on the lower strength and higher corrosion resistance side. It can be cold worked to produce tempers with a higher strength but a lower ductility
3102 aluminum is a 3000-series aluminum alloy: the main alloying addition is manganese, and it is formulated for primary forming into wrought products. 3102 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-3102. A93102 is the UNS number. Additionally, the EN chemical designation is AlMn0,2.
It originally received its standard designation in 1972. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
It can have the lowest tensile strength among the 3000-series alloys in the database.
The properties of 3102 aluminum include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 3102 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.
