The main differences between 5086 and 5052 aluminum alloys lie in their strength, corrosion resistance, and formability. 5086 is stronger and more corrosion-resistant, making it ideal for heavy-duty applications like large boat hulls, while 5052 is more formable and less expensive, making it suitable for applications that may experience impacts, such as small boat bottoms or fuel tanks. 5086 has higher tensile and yield strengths than 5052, but 5052 offers greater elongation, meaning it can stretch more before breaking.
| Feature | 5086 Aluminum | 5052 Aluminum |
|---|---|---|
| Strength | Higher tensile and yield strength | Lower tensile and yield strength |
| Formability | Less formable, more prone to cracking during bending | More formable and ductile ("stretchier") |
| Corrosion Resistance | Superior corrosion resistance | Good corrosion resistance, but less than 5086 |
| Typical Applications | Large boat hulls, demanding marine structures, pressurized vessels | Small boat bottoms, fuel tanks, general sheet metal work |
| Cost | More expensive | Less expensive |

When it comes to welding marine components like fuel tanks for boats, selecting the right aluminum alloy is essential. While 5052-H32 has been a popular choice for many years, 5086-H116 aluminum offers distinct advantages that make it the superior option for marine welding applications.
Strength and Durability
5086-H116 aluminum provides higher strength than 5052-H32, making it better suited for demanding marine environments. The ultimate tensile strength of 5086-H116 is approximately 40-44 ksi, compared to 33-38 ksi for 5052-H32. This increased strength translates into improved durability and a longer lifespan for welded components such as fuel tanks, which experience continuous stress and vibration in marine conditions.
Corrosion Resistance
Both 5086-H116 and 5052-H32 offer excellent corrosion resistance, which is crucial for marine applications. However, 5086-H116 has a slight advantage in seawater corrosion resistance, making it a better choice for components frequently exposed to saltwater, like fuel tanks and other boat structures.
Weldability
One of the key benefits of 5086-H116 over 5052-H32 is its superior weldability. 5086-H116 maintains most of its mechanical strength after welding, which is vital for the integrity of fuel tanks and other welded marine structures. This property allows for stronger, more reliable welds that can endure the harsh marine environment.
Formability
While both alloys are formable, 5086-H116 is generally more formable than 5052-H32. This is particularly advantageous when creating complex shapes or curves, as often required for boat fuel tanks and other marine components. The improved formability of 5086-H116 enables easier shaping and bending without compromising the material's strength or integrity.
Marine Industry Preference
The marine industry has increasingly favored 5086-H116 for applications requiring higher strength and excellent welding properties. Its widespread use in shipbuilding, especially for boat hulls and superstructures, highlights its superior performance in marine environments.
Conclusion
While 5052-H32 is still a reliable choice for many applications, 5086-H116 aluminum outperforms it when it comes to welding marine components like fuel tanks for boats. With its higher strength, superior corrosion resistance, excellent weldability, and better formability, 5086-H116 is the ideal alloy for marine welding applications. By choosing 5086-H116, boat manufacturers and marine engineers can ensure stronger, more durable, and longer-lasting welded structures that will withstand the challenges of marine environments.
