As a leading supplier from Hemaokang Steel (Shandong) Co., Ltd., we proudly offer the 5083 H116 Aluminum Round Bar 50mm Dia – a premium marine-grade alloy designed specifically for shipbuilding and offshore applications. With our ISO9001-certified quality management system and an annual export value exceeding US$50 million, we ensure that every round bar meets rigorous international standards for corrosion resistance and structural integrity. This product combines exceptional strength with lightweight properties, making it the ideal choice for demanding maritime environments.
Our 5083 H116 aluminum round bar is manufactured using advanced production techniques, resulting in a uniform microstructure and consistent mechanical properties. The H116 temper provides optimal hardness and stress-corrosion cracking resistance, while the 50mm diameter is a common size for ship frames, rails, and structural supports. Below, we detail the key specifications and benefits of this high-performance material.

Detailed Product Advantages
- Exceptional Marine-Grade Performance: Alloy 5083 is specifically designed for seawater applications, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. The H116 temper further enhances this property, making it suitable for long-term exposure in shipbuilding.
- High Strength-to-Weight Ratio: With a tensile strength of ≥290 MPa and a density of only 2.66 g/cm³, this round bar provides the structural strength needed for hulls, decks, and superstructures while reducing overall vessel weight – leading to fuel efficiency and increased payload capacity.
- Excellent Weldability and Machinability: 5083 H116 aluminum can be easily welded using common techniques (MIG, TIG) without significant loss of strength. It also machines well, allowing for precise fabrication of complex components.
- Uniform Dimensions and Tight Tolerances: Each 50mm diameter bar is produced with a strict tolerance of ±0.5 mm, ensuring consistency in your manufacturing processes. Custom lengths are available to reduce material waste.
- Low Maintenance Requirements: The natural oxide layer on aluminum provides long-term protection. In marine environments, 5083 H116 requires minimal maintenance compared to steel or other alloys, lowering overall lifecycle costs.
- Versatile Application Range: Beyond shipbuilding, this round bar is also used in offshore platforms, marine equipment, chemical processing, and transportation industries where corrosion resistance is critical.

Frequently Asked Questions
-
Q: What is the difference between 5083 H116 and 5083 H321?
A: H116 temper offers improved stress-corrosion cracking resistance compared to H321, making it the preferred choice for marine applications. H116 is specifically designed for use in seawater. -
Q: Can you supply custom lengths beyond 6 meters?
A: Yes, we can supply custom lengths up to 12 meters upon request, subject to minimum order quantities. Please contact our sales team for details. -
Q: Is this product suitable for welding without preheating?
A: 5083 H116 has excellent weldability and can be welded without preheating for most applications. However, for thick sections, a slight preheat (100°C) may be recommended to avoid cracking. -
Q: What certifications are provided with the shipment?
A: We provide a Mill Test Certificate (MTC) that includes chemical composition, mechanical properties, and traceability. ISO9001 certification is also available upon request. -
Q: Does the round bar come with any surface treatment?
A: Standard delivery is mill finish. We can also supply with anodized or polished surface as an option – please specify your requirement. -
Q: How do you ensure corrosion resistance for long-term storage?
A: The bars are packaged with protective wrapping to prevent moisture damage. They are also stored in a dry warehouse. For extended storage, we recommend keeping them in a ventilated area. -
Q: What is the minimum order quantity for this 50mm diameter bar?
A: The MOQ is typically 500 kg for standard sizes. For smaller quantities, please inquire – we may accommodate sample orders. -
Q: Can you ship to our port in South America?
A: Absolutely. We export to all major markets worldwide, including South America. Our logistics team will arrange the most cost-effective shipping method.
