3105 Aluminum sheet belongs to the Al-Mn series of rust-proof aluminum alloys and is a core representative of the 3000 series aluminum sheets.
3105 Aluminum sheet belongs to the Al-Mn series of rust-proof aluminum alloys and is a core representative of the 3000 series aluminum sheets. Its tensile strength ranges from 120 to 160 MPa, with a yield strength of ≥85 MPa, combining excellent ductility and corrosion resistance. This material cannot be strengthened through heat treatment but can enhance mechanical properties through cold working. It is widely used in deep drawing and decorative applications.

Manganese forms a dense oxide layer, resisting salt, alkali, and acid rain corrosion—ideal for humid environments.
Contains 0.3% copper, achieving 41% conductivity, making it suitable for electronic component housings.
It features excellent deep-drawing, forming, and welding capabilities, facilitating the production of complex-shaped parts and improving manufacturing efficiency.
Low density (2.73 g/cm³) reduces transportation and installation costs while improving structural efficiency.
Recyclable, complies with green building standards, and reduces carbon emissions.
More affordable than 5000-series aluminum alloys, widely used in the market, lowering overall costs.
"Our factory has been using 3105 aluminum for bottle caps, and the results are fantastic! Its rust resistance is outstanding—no corrosion even after long-term storage. The surface printing remains sharp, and customer feedback has been excellent. Plus, the conductivity of 3105 aluminum improves the stability of our automated production line, reducing downtime. We’ve already recommended it to many peers!"
