3000 Series High Gloss 3105 Aluminum Alloy Coil With Superior Formability
3105 is a manganese (Mn)-based aluminum alloy known for its excellent formability, corrosion
resistance, and moderate strength, making it a cost-effective choice for commercial applications.
Common Thicknesses & Tempers
| Thickness (mm) | Temper | Characteristics |
| 0.2–0.5 | H14/H24 | Half-hard, balanced strength/formability for precision parts |
| 0.5–1.0 | H16/H26 | Higher rigidity for structural components |
| 1.0–3.0 | O (Annealed) | Soft state, optimal for deep drawing |
| 3.0–6.0 | H18/H38 | Full-hard, high-strength for load-bearing uses |
Key Performance Advantages
♦ Superior Corrosion Resistance
Contains magnesium (Mg) and manganese (Mn) for enhanced oxidation resistance, outperforming
pure aluminum (1xxx series) in humid/industrial environments.
♦ Optimal Strength-Formability Balance
Tensile strength: 115-150 MPa
Elongation: 10-20%
Excellent for stamping, bending, and deep drawing without cracking.
♦ Superior Surface Treatment Compatibility
Ideal base for painting, anodizing, or laminated finishes (e.g., color-coated, stone-patterned).
♦ Lightweight & Cost-Effective
Density: 2.7 g/cm³; more economical than 5xxx series alloys.
Primary Applications
• Architectural Decoration
Curtain walls/ceilings: Thickness 0.5–1.5mm (H14/H24), lightweight & weather-resistant.
Color-coated base material: For PVDF or stone-pattern finishes.
• Appliances & Electronics
Refrigerator/AC panels: 0.4–0.8mm (O/H14), easy stamping.
Electronic enclosures: EMI shielding (e.g., junction box covers).
• Transportation
Vehicle interiors: 1.0–2.0mm (H16/H26) for weight reduction.
Marine partitions: Saltwater-resistant with protective coatings.
• Packaging
Beverage can ends/lids: Ultra-thin (0.2–0.3mm, H18), superior sealability.
Our Company Advantages
• All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland) Company.They
improve the quality of Aluminum alloy slab which can guarantee Aluminium alloy products with
high performance.
• 1+1+4 hot rolling mills and 1+5 hot rolling mills from SMS Group (Germany). All the hot finishing
rolling mills adopt the CVC flatness control technology, which can produce hot-rolled coils and sheets
with ideal flatness.
• 6 sets of cold rolling mills from SMS Group (Germany). All these mills are applied with SMS patent
6-High CVC technology and are the most advanced cold rolling mills in the world currently.
