Aluminum plate 5083 H116 is one of the essential materials in the maritime industry. This alloy meets ASTM B209 standards and is certified by various classification societies.
This article will help you understand ASTM standards, technical requirements, and practical applications of aluminum 5083 H116.
1. ASTM B209 – The Crucial Standard for Aluminum Plate 5083 H116
1.1. What is ASTM B209?
ASTM B209 is a technical standard applied to aluminum and aluminum alloy plates, sheets, and strips. This standard specifies requirements for chemical composition, mechanical properties, and corrosion resistance.
Aluminum 5083 H116 contains 4% – 4.9% magnesium (Mg), enhancing its strength and corrosion resistance. This aluminum type is widely used in the maritime industry due to its excellent seawater resistance.
1.2. How Does Aluminum 5083 H116 Meet ASTM B209 Standards?
To comply with ASTM B209, aluminum 5083 H116 must meet the following criteria:
- Tensile strength: 305 – 385 MPa
- Yield strength: Minimum 215 MPa
- Elongation: Above 12% (depending on thickness)
- Corrosion resistance: Excellent in marine environments
Aluminum 5083 H116 offers high load-bearing capacity and minimal cracking in extreme conditions.
2. ABS, BV, DNV Technical Requirements for Aluminum 5083 H116
2.1. What are ABS, BV, and DNV?
Classification societies such as ABS (American Bureau of Shipping), BV (Bureau Veritas), and DNV (Det Norske Veritas) set strict standards for marine materials.
Aluminum 5083 H116 must pass rigorous tests to obtain certification from these organizations.
2.2. ABS, BV, DNV Requirements for Aluminum 5083 H116
a. Mechanical Strength
- The tensile strength and yield strength must meet or exceed ASTM B209 standards.
- High elongation enhances impact resistance.
b. Corrosion Resistance
- Aluminum 5083 H116 must exhibit excellent resistance to seawater corrosion.
- The material undergoes saltwater exposure tests before certification.
c. Quality Control
- Hardness, thickness, and weldability tests are conducted.
- The material must be free from surface defects and cracks.
Once aluminum 5083 H116 meets these requirements, it is certified for maritime applications.
3. Quality Comparison of Aluminum 5083 H116 vs. Other Aluminum Types
3.1. Comparison with Aluminum 5083 H111
| Characteristics | Aluminum 5083 H116 | Aluminum 5083 H111 |
|---|---|---|
| Hardness | Higher | Lower |
| Corrosion resistance | Superior | Good but lower than H116 |
| Weldability | Good | Excellent |
| Main applications | Shipbuilding, offshore structures | Lightweight structures, non-marine applications |
Aluminum 5083 H116 has better hardness and corrosion resistance than H111, making it more suitable for maritime applications.
3.2. Comparison with Aluminum 5052
Aluminum 5052 also has good corrosion resistance but is not as strong as aluminum 5083 H116. Aluminum 5052 is typically used for lighter load-bearing structures.
For high-strength applications in marine environments, aluminum 5083 H116 is the superior choice.
