ASTM B209 AA5251 5251 Alloy Aluminum Coil Chinese Supplier

Alloy 5251 is a non-heat treatable rolled product supplied as either sheet or coil. 5251 is stronger than 5005 and is used in applications requiring more structural integrity or impact resistance. 5251 has excellent corrosion resistance, medium static strength, medium to high fatigue strength, good weldability and very good corrosion resistance especially in marine applications.

• Moderate Mg content (2.0-2.5%) offering balanced strength
• Exceptional corrosion resistance - outperforms 5052 in marine environments
• Excellent weldability - suitable for MIG/TIG welding
• Anodizing-friendly with good surface treatment adaptability
• Cost-performance leader between 5052 and 5083 alloys

We introduced world-leading technology and equipment, including advanced vertical intelligent storage, logistics systems, and finishing lines, to meet all production demands for aluminum plates, coils and strips.

For oversize sheet, we use Flat Rack Container with specialized securing methods:

• We use suitable securing material, such as wooden blocks, steel straps, and ratchet tie-downs to firmly fix the aluminum plates to the flat rack.
• To prevent possible exposure to seawater or rain, we cover the entire cargo with waterproof tarps.
• We make sure these sheets are loaded with a low and evenly distributed center of gravity to avoid tilting during the transportation.
