Product Description
Product Description:3105 aluminum alloy is an aluminum-manganese alloy (mainly composed of Al-Mn-Mg) with excellent formability, corrosion resistance and medium strength. The combination of 1.0 mm thickness and 1250 mm width, combined with color coating processes such as PVDF or PE coating, makes it an ideal material for construction, transportation, packaging and other fields.
Core features:Chemical composition: Mn (0.3-0.8%), Mg (0.2-0.8%), optimized strength and ductility.
Mechanical properties: tensile strength ≥ 140 MPa, elongation ≥ 10%.
Coating process: PVDF (super weather resistance), PE (economical), support RAL/Pantone color card customization.
Surface treatment: smooth, matte or embossed (e.g. wood grain, stone grain).
International Certifications:
ASTM B209 (American Standard Aluminum Sheet Specification), EN 485 (European Standard for Aluminum).
Environmental certification: RoHS, REACH compliant, support LEED green building score.

Product Advantages
| Advantage |
Detailed description |
| Lightweight design |
With a density of only 1/3 of steel, it significantly reduces transportation and installation costs and is suitable for large construction and vehicle components. |
| Excellent weather resistance |
The PVDF coating provides more than 30 years of color fidelity and resistance to UV, acid rain and salt spray corrosion (suitable for coastal areas). |
| Excellent processability |
High ductility (H24/H26 state) supports complex forming processes such as cold forming, stamping, and welding. |
| Aesthetic diversity |
Customizable colors (metallic, matte) and textures are available to meet the visual needs of high-end architecture and consumer goods. |
| Environmentally sustainable |
100% recyclable, reducing carbon footprint and complying with EU Circular Economy Act. |
Application scenarios and cases in the international market:
1. Architecture and curtain wall field
