ASTM B209 Weldable 5005 5052 5083 Aluminum Plate 6mm 10mm 20mm Marine Grade Corrosion Resistant Tight Tolerance

Our 5005 / 5052 / 5083 aluminum plate is a high-strength Al-Mg marine grade alloy plate, widely used in shipbuilding, pressure vessels, marine structures and tank trailers. It combines excellent weldability, outstanding corrosion resistance and 100% recyclability, making it the first choice for demanding engineering projects.

• Excellent Weldability: 5083 alloy retains exceptional strength after welding and is the highest strength non-heat-treatable alloy, while 5005 and 5052 offer excellent weldability and formability, ideal for welded structures such as ship hulls, pressure vessels and storage tanks.
• Full Certification & Standards: Manufactured to ASTM B209, EN 485 and GB/T 3880 standards, with ISO 9001:2015 quality management and ABS/DNV marine classification available on request.
• Precision Tolerance: Tight thickness tolerance of +/- 0.05mm and flatness within 3mm/m ensure stable dimensional accuracy for precision fabrication and CNC machining.
• Custom Processing Service: One-stop processing services including cutting to size, bending, punching, CNC machining, decoiling and welding to reduce your production lead time and cost.
• 100% Recyclable & Eco-Friendly: Aluminum can be recycled indefinitely without loss of properties, supporting green procurement policies and low-carbon construction projects.

We offer a complete range of surface finishes to match your aesthetic and functional requirements:

• Stucco Embossed: Uniform raised stucco texture providing anti-slip, anti-scratch and wear-resistant performance, ideal for trailer interiors, walk-in cooler liners and decorative wall panels.
• Pre Painted: Factory-applied paint coating in white, gloss white or custom colors, offering excellent weather resistance, color stability and low maintenance for building facades and refrigeration applications.
• Color Coated: Polyester or PVDF color coated surface for exterior wall cladding, roofing and architectural decoration with long-lasting color retention.
• Anodized: Electrochemical anodizing creates a hard, corrosion-resistant oxide layer available in natural silver, bronze, black and other colors, ideal for architectural and outdoor applications.
• Polished: Mirror-like polished surface with high reflectivity, perfect for lighting fixtures, decorative panels, signs and solar reflectors.
• Brush Finish: Fine brushed texture with a modern matte appearance, widely used for elevator panels, kitchen appliances, electronics housings and interior decoration.

Thanks to its high strength, excellent weldability and superior corrosion resistance, 5005 / 5052 / 5083 aluminum plate is trusted across a wide range of industries worldwide:

• Shipbuilding & Marine Engineering: Ship hulls, decks, bulkheads, superstructures, patrol boats, yachts, fishing vessels and offshore platforms that require long-term resistance to seawater corrosion.
• Pressure Vessels & Storage Tanks: Liquid tankers, petroleum tank trailers, chemical storage tanks, cryogenic vessels and pressure vessels where welded joint reliability and leak safety are critical.
• Transportation & Automotive: Truck bodies, trailers, container floors, metro and railway carriage flooring, bus body panels and vehicle armor plates for lightweight and fuel efficiency.
• Aerospace & Defense: Spacecraft fuel tanks, missile components, aircraft structural parts and military equipment requiring high strength-to-weight ratio and weldability.
• Construction & Architecture: Building facades, curtain walls, roofing systems, bridges, stadium structures, escalator panels and decorative cladding with long service life.
• Industrial Fabrication: Welded machine frames, chemical equipment, heat exchangers, food processing equipment, mold bases and general engineering components.
• Energy & New Energy: Wind power tower internals, solar panel frames, battery enclosure housings, LNG storage facilities and power transmission structures.
• Metro & Public Infrastructure: Metro flooring panels, station interior cladding, noise barriers, highway sign structures and public facility panels with fire safety and durability requirements.
