Product Description:
Alloy 3105 is an aluminum-manganese alloy (Al-Mn-Mg) with excellent formability, corrosion resistance and moderate strength, making it suitable for applications that require lightweight and weatherability. The combination of 1.2 mm thickness and 1250 mm width, combined with color coating process (PVDF or PE coating), makes it an ideal material for construction, transportation, home appliances and other fields.
Key features:
Chemical composition: Mn (0.3-0.8%), Mg (0.2-0.8%), optimized corrosion resistance and processability.
Mechanical properties: tensile strength ≥ 140 MPa, elongation ≥ 10%, suitable for cold bending, stamping and other processing.
Coating process: PVDF (super weather resistance, 30 years color retention), PE (economical, bright color), support RAL/Pantone color card customization.
International certification: ASTM B209 (American standard), EN 485 (European standard), JIS H4000 (Japanese standard), in line with RoHS, REACH environmental protection standards.
