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

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.
