Product Description
Our 2xxx series aluminum coils (including 2024, 2017, and 2219) are engineered for industrial applications demanding exceptional corrosion resistance and high fatigue strength under cyclic loading. These coils feature robust Al-Cu-Mg alloys with dual cladding layers (0.03–0.08 mm thick 1100 aluminum) to create a protective barrier against saltwater, industrial chemicals, and atmospheric exposure. With customizable widths (up to 2500 mm) and versatile temper conditions (O, T3, T4, T6), they serve as reliable materials in marine, chemical processing, and architectural sectors where durability is paramount.

Dual Clad Protection: A pure aluminum layer (1100 alloy, ≥99.0% Al) on both sides acts as a sacrificial anode, preventing galvanic corrosion in aggressive environments such as coastal areas and chemical plants.
Superior Weldability: Compatible with TIG, MIG, and resistance welding processes, with low distortion (≤0.5% dimensional change) during fabrication, reducing post-weld straightening needs.
Enhanced Formability: High ductility (elongation up to 18% in O temper) allows deep drawing, roll forming, and bending into complex shapes without cracking or surface damage.
Application-Specific Customization:
Surface Treatments: Chromate conversion coating (for marine applications) or epoxy primers (for chemical resistance) to extend service life in harsh conditions.
Temper Options: Full-hard (H18) for structural components requiring rigidity, or annealed (O) for intricate forming in architectural trim.
Marine Industry: Ship hull cladding, offshore platform decking, desalination equipment heat exchangers, and boat hull panels.
Chemical Processing: Reaction vessel linings, storage tank walls, pipeline cladding, and acid-resistant flooring.
Architecture: Exterior cladding for coastal buildings, curtain walls in industrial zones, and corrosion-resistant roofing systems.
Automotive: Fuel tanks for commercial vehicles, heat exchangers, and underbody structural components.
Q: How does the cladding affect cost?
A: Clad coils are 10–15% more expensive than bare alloys but offer 5x longer service life in corrosive environments, reducing long-term replacement costs.
Q: Can you provide marine-grade certifications?
A: Yes, our coils meet DNV GL, ABS, and LR (Lloyd's Register) standards for marine applications, with test reports available upon request.
Q: What is the shelf life?
A: When stored in dry, covered facilities with humidity ≤60%, properly packaged coils remain corrosion-free for 3–5 years.
Q: Do you offer cut-to-length services?
A: Yes, we provide precision cutting to lengths of 1–10 meters with a tolerance of ±2 mm.
Combine with our 2xxx series extrusions (angles, channels, tubes) for structural frameworks, or apply our polyurethane coatings (UV-resistant, chemical-resistant) to further enhance corrosion protection. For critical applications, our non-destructive testing (NDT) services (ultrasonic, eddy current) ensure material integrity before delivery.
