What is Naval Brass?
Naval Brass , also known internationally as Naval Brass or Admiralty Brass , is an alloy of copper (Cu) and zinc (Zn) to which a small but crucial amount of tin (Sn) is added , usually around 1%. The typical composition is approximately 60% Cu, 39% Zn and 1% Sn . Tin is the key element that gives this alloy its exceptional corrosion resistance in saltwater environments , particularly against dezincification .
Dezincification is a type of corrosion that affects brasses, where zinc selectively dissolves from the alloy, leaving a porous and weakened copper structure. The addition of tin to Naval Brass significantly inhibits this phenomenon, making the alloy ideal for applications in marine environments, where seawater and salts are highly corrosive to other brasses. Furthermore, Naval Brass maintains good strength, ductility, and machinability .
Key Properties of Naval Brass:
- Excellent Corrosion Resistance in Salt Water: The main advantage, thanks to the addition of tin which inhibits dezincification.
- Good Mechanical Resistance: Offers adequate resistance for structural and pressure components.
- Good Ductility and Machinability: Easy to work, form and machine.
- Erosion-Corrosion Resistance: Able to withstand wear from the flow of corrosive liquids.
- Non-Ferromagnetic: It is not magnetic, which is useful in applications where magnetism could interfere.
- Golden Yellow Color: Aesthetically appealing, although functional application is the priority.
Features and Specifications of Naval Brass:
We market Naval Brass in a wide variety of grades, shapes, and specifications to suit the needs of various industries:
- Chemical Composition:
- Naval Brass (Standard Naval Brass): Typically ASTM B21 / UNS C46400 (60% Cu, 39.2% Zn, 0.8% Sn).
- Admiralty Brass: Typically ASTM B111 / UNS C44300 (70% Cu, 29% Zn, 1% Sn, with a small addition of Arsenic, Antimony or Phosphorus to further improve dezincification resistance).
- Other grades may have minor variations in tin or zinc content, or include traces of other elements for specific properties.
- Format:
- Bars: Round, square, hexagonal, flat, for shafts, fasteners, valve components, bushings, marine rivets.
- Plates and Sheets: For bulkheads, ship hulls, condensers and heat exchange equipment.
- Tubes and Pipes: Especially for condensers, heat exchangers and seawater systems.
- Forgings: For high-strength components subjected to marine environments.
- Condition: Can be supplied in annealed condition (for maximum ductility) or cold work hardened (for strength and hardness).
- Surface Finish: From a rough rolled finish to a polished finish, depending on the final application.
Main industrial applications of Naval Brass:
Naval Brass is an irreplaceable material in applications where corrosion resistance in seawater is essential:
- Naval and Marine Industry:
- Ship Components: Propeller shafts, hull fittings, pump components and marine valves.
- Heat Exchangers and Condensers: In ship cooling systems, power plants and desalination plants.
- Marine Piping Systems: Seawater pipelines.
- Offshore Oil Platforms: Components exposed to the marine environment.
- Diving and Underwater Equipment: Housings and connectors.
- Pumps and Valves: For handling corrosive liquids or seawater.
- Marine Fasteners: Bolts, nuts, rivets in marine environments.
- Chemical Industry: Equipment that handles saline solutions.
Marketing formats:
We supply Naval Brass in the formats that best suit the logistics and needs of your project:
- Per Ton (TM) or Kilogram (KG): We adapt to the volumes required by your production or project.
- By Batch or Complete Project: Management of large and complex orders, ensuring consistency in quality and specifications.
- Cut to Size: Possibility of supplying material with specific dimensions upon request to optimize your manufacturing process.
- Packaging and Protection: Material is carefully packaged and protected to prevent physical damage and oxidation during transport and storage, using packaging appropriate for its shape (bar bundles, coils, tubes, etc.). Protection against moisture is a priority during transoceanic transport.
Logistics are tailored to each destination and volume, ensuring compliance with national and international regulations for the transportation of copper alloys, with safe and efficient handling.
