Al-Mn Series 3105 Anodized Aluminum Alloy For Refrigerator Panel
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
Refrigerator panels typically utilize 3105 aluminum sheets ranging from 0.5-1.2mm
• 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
The material is most commonly supplied in H14 or H24 half-hard tempers
Tensile strength: 150～200 MPa
Elongation: 4%～8%
Balances formability and flatness, ideal for stamping/roll coating
Anodized Treatment Key Advantages
♦ Produces a premium metallic finish with exceptional surface smoothness and fingerprint resistance
♦ Creates outstanding corrosion resistance that maintains long-term aesthetic quality
♦ Offers inherent lightweight properties that reduce overall product weight
♦ Provides excellent formability for complex shaping requirements
♦ Enables durable, vibrant color options through electrolytic coloring
Performance Advantages
| Property | Benefits |
| Surface Quality | Mirror finish (Ra≤0.2μm) after anodizing, fingerprint-resistant |
| Corrosion Resistance | Anodized layer + sealing passes 500h salt spray test (Grade 9+) |
| Lightweight | Density 2.73g/cm³ (35% lighter than stainless steel) |
| Formability | 180° bending (R≥1t) achievable in H14 temper without cracking |
| Color Stability | ΔE＜1.5 after 10 years UV exposure (electrolytic coloring) |
Color Options:
Standard: Silver (natural anodized)
Trendy: Champagne gold/Titanium gray (electrolytic coloring)
Typical Applications
Compared to traditional stainless steel or painted steel alternatives, anodized 3105 aluminum panels
demonstrate clear advantages in cost efficiency, weight reduction, and manufacturing flexibility. These
benefits have established the material as the preferred choice for premium refrigerator models from
leading appliance brands like Haier and Midea.
