What Makes Aluminum “Marine Grade”?
Marine aluminum alloys are designed for:
- Saltwater corrosion resistance
- Long-term durability
- Weldability in harsh environments
Most marine grades use magnesium to improve corrosion resistance.
Why Marine Aluminum Is Preferred
Compared to steel:
- Lighter weight
- Better corrosion resistance
- Lower maintenance requirements
