Marine environments present unique challenges for metal components due to saltwater corrosion. Brass alloys, particularly naval brass and DZR alloys, provide excellent performance in maritime applications.
Marine Challenges
- Saltwater corrosion
- Galvanic corrosion with other metals
- Biofouling
- Erosion from water flow
- Temperature variations
Marine Brass Alloys
Naval Brass (C46400)
Contains 1% tin for enhanced corrosion resistance in seawater. Ideal for ship hardware, propellers, and underwater fittings.
DZR Brass (Dezincification Resistant)
Silicon brass with controlled zinc content. Prevents dezincification in aggressive water conditions.
Aluminum Brass
Enhanced corrosion resistance with 2% aluminum. Suitable for heat exchangers and condensers.
Marine Applications
- Ships hull fittings
- Seacock and through-hull fittings
- Propeller shafts
- Heat exchangers
- Marine pumps and valves
- Deck hardware
Maintenance
Regular inspection and cleaning extend marine brass component life. Protective coatings can provide additional corrosion resistance in severe environments.
