3000 Series 3105 Anodized Aluminum Coil For Refrigerator Panels

3000 Series 3105 Anodized Aluminum Coil For Refrigerator Panels

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.

Anodized 3105 aluminum alloy has become the material of choice for premium refrigerator panels

due to its exceptional combination of properties and performance characteristics.

Standard Thickness

Range: 0.5mm～1.2mm

Main door panel: 0.8～1.0mm (optimizes strength-to-weight ratio)

Decorative trims/handles: 0.5～0.7mm (for bending/formability)

Oversized panels: 1.0～1.2mm (prevents warping)

Recommended Tempers

H14/H24 (Half-hard):

Tensile strength: 150～200 MPa

Elongation: 4%～8%

Balances formability and flatness, ideal for stamping/roll coating
