Shandong Sino Steel Co., Ltd. is proud to present our premium 5052 Aluminum Coil H32 Temper in thicknesses ranging from 0.5mm to 4mm, specifically engineered for demanding marine applications. As a manufacturer with over 5 years of expertise and a dedicated overseas office, we deliver coils that combine exceptional corrosion resistance with high strength-to-weight ratio, making them the ideal choice for shipbuilding, offshore platforms, and marine equipment. Our ISO9000 and ISO19011:2000 certified production processes ensure consistent quality and reliable performance in harsh saltwater environments.
The 5052 aluminum alloy is widely recognized for its excellent weldability, formability, and fatigue resistance, while the H32 temper provides a balanced combination of strength and workability. Whether you need coils for hull structures, deck panels, or marine piping systems, our product meets the rigorous standards of the maritime industry. Below we detail the key features, technical specifications, and benefits that set our 5052 aluminum coil apart.
Key Features & Benefits
- Superior Corrosion Resistance – The 5052 alloy contains high magnesium content, providing excellent resistance to seawater and salt spray, significantly extending service life in marine environments.
- High Strength & Lightweight – With a tensile strength range of 210–260 MPa, this coil offers a great strength-to-weight ratio, reducing structural load while maintaining durability.
- Excellent Weldability & Formability – Suitable for TIG, MIG, and resistance welding; can be easily bent, stamped, or deep drawn without cracking.
- Precise Thickness Control – Available from 0.5mm to 4mm with tight tolerances (±0.02mm typical), ensuring consistent performance in fabrication.
- H32 Temper Optimized – Strain-hardened and partially annealed, providing a stable condition that is ideal for forming and welding without excessive springback.

Detailed Product Description
Our 5052 aluminum coil is manufactured using advanced continuous casting and rolling technology, ensuring uniform metallurgical structure and dimensional accuracy. The H32 temper is achieved through controlled strain hardening and partial annealing, resulting in a stable condition that is neither too soft nor too hard – ideal for marine fabrication where both strength and formability are required.
The high magnesium content (2.2%–2.8%) in 5052 alloy provides natural protection against pitting corrosion and stress corrosion cracking, which are common issues in marine environments. This makes the coil suitable for direct contact with seawater, such as in boat hulls, fuel tanks, and marine hardware. The material also offers excellent fatigue resistance, ensuring long-term reliability under cyclic loading.
For customers requiring specific dimensions, we offer flexible width and thickness customization. Our coils are supplied in standard diameters of 500–800 mm, with inner diameters of 300 mm or 500 mm (customizable). Each coil is carefully inspected for surface defects, edge condition, and thickness variation before packaging.
We understand that marine applications demand the highest quality standards. Therefore, every coil is traceable with mill test certificates, and we can provide third-party inspection reports upon request. Our production lines are equipped with real-time monitoring systems to ensure compliance with international standards such as GB/T 3880 and ASTM B209.

Frequently Asked Questions
Q1: What is the difference between 5052 and 5083 aluminum for marine use?
A: Both alloys are excellent for marine applications. 5052 offers good strength and corrosion resistance at a lower cost, while 5083 provides higher strength and is often used for larger vessels. For many applications like small boats, fuel tanks, and architectural marine components, 5052 is a cost-effective choice.
Q2: Can the 5052 aluminum coil be welded easily?
A: Yes, 5052 alloy has excellent weldability using common techniques like TIG or MIG welding. It is less prone to hot cracking compared to higher-strength alloys, making it ideal for fabrication in shipyards.
Q3: What surface finishes are available?
A: Standard finish is mill finish. We also offer coated options (e.g., PVDF, polyester) for enhanced corrosion resistance or aesthetic purposes. Please contact us for customized surface treatments.
Q4: What is the minimum order quantity?
A: MOQ depends on thickness and width. Typically, we accept orders from 1 ton for standard sizes. For non-standard dimensions, please inquire with our sales team.
Q5: Can you provide samples before mass production?
A: Yes, we can provide small samples (e.g., 300mm x 300mm) for testing. The sample cost is usually negotiable, and shipping is at the customer's expense.
Q6: How do you ensure the coil is free from defects?
A: We perform visual inspection, thickness measurement, and mechanical testing on each coil. Additionally, we can arrange third-party inspection (e.g., SGS, BV) if required.
Q7: What is the typical lead time?
A: For standard thicknesses and widths, lead time is 15–25 days after order confirmation. Custom sizes may take longer depending on production schedule.
Q8: Is the coil suitable for fresh water tanks as well?
A: Absolutely. 5052 aluminum is safe for potable water contact and is often used in water tanks, piping, and food processing equipment due to its corrosion resistance and non-toxic nature.
