3000 Series Aluminum (Manganese)

The 3xxx series of aluminum alloys contain manganese as the principal alloying element. While manganese doesn’t significantly increase strength when strain-hardened, these alloys offer high formability, ductility, and excellent corrosion resistance in most environments. They are easily weldable and are well-suited for brazing and soldering applications.

In commercial aluminum-manganese alloys, manganese content can go up to 1.2%. Additionally, it’s important to mention that manganese is often used as an additional alloying element in other series of aluminum alloys to improve their strength.
