3102 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is one of the most lightly alloyed grades 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.
