Aluminum Alloy 5052 Aluminum Sheet for Marine Interior Panels | Thickness 1.5–3.0 mm |Customizable Width | Anodized / Protective Coating

Introduction                                                

The 1.5–3.0 mm 5052 aluminum sheet with anodized or protective coating is currently the global marine industry standard for high-end interior panels, bulkheads, cabin linings, ceilings, furniture accents, galley surfaces and wet-area cladding in yachts, superyachts, cruise ships and offshore accommodation modules.

Compared to 5083/5086 (stronger but heavier & more expensive) or 3003/3105 (lighter but insufficient corrosion resistance), 5052 delivers the optimal marine interior sweet spot:

Mg alloying (2.2–2.8%) → best-in-class saltwater corrosion resistance among anodizable alloys

High strength-to-weight ratio → rigid panels without excessive thickness

Outstanding anodizing response → crystal-clear, uniform, hard anodic film with premium metallic look

Excellent formability & weldability for curved bulkheads & complex joinery

Surface options:Anodized (20–30 μm AA20–AA25 marine-grade): natural silver, champagne, black, custom dyes,Protective coating (polyester PE 25–35 μm or PVDF 25–35 μm): solid colors, metallic, anti-fingerprint nano topcoat,Warranty: anodized 25–30 years / coated 20–30 years (indoor marine environment)

FAQ (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 5052 over 5083 or 5086 for marine interior panels?

A: 5052 offers excellent marine corrosion resistance and anodizing quality while being 15–25% cheaper and easier to form than 5083/5086. It is the sweet spot for non-structural interior fit-out.

Q2: How durable is the anodized finish in high-humidity / saltwater environments?

A: AA20–AA25 anodizing passes 6000 h salt-spray; no pitting or discoloration after years in yacht interiors. Real marine exposure & humidity chamber test data provided.

Q3: Can the sheet be curved or roll-formed for rounded bulkheads & staircases?

A: Yes — 5052 has excellent formability (2T–3T bend radius). We supply curved samples & forming limit diagrams (FLD) for your specific radius.

Q4: Minimum order quantity & lead time for custom anodized colors?

A: MOQ 3–5 tons (depending on color); standard silver/black 15–25 days; custom dye match 25–35 days. Sample sheets free with freight collect.

Q5: Is 5052 non-magnetic & suitable for compass-sensitive areas?

A: Yes — 5052 is non-ferrous and non-magnetic, making it ideal for navigation & bridge interior panels near compasses.

Q6: How does 5052 perform with regard to fire safety & smoke classification?

A: Anodized or coated 5052 meets IMO FTP Code & EN 13501-1 Class B-s1,d0 (very low flame spread & smoke). Full fire test certificates available.
