Neval Brass
Naval Brass is a traditional marine alloy known for its high strength and excellent corrosion resistance. It typically contains about 60% copper, 0.75% tin, and 39.2% zinc. The presence of tin significantly improves the alloy’s resistance to dezincification, making it especially reliable in marine environments.
This alloy is widely used in marine construction and engineering applications where a strong, durable, and corrosion-resistant material is required. Naval Brass performs well in both saltwater and freshwater conditions.
Naval Brass alloys are valued for their good strength, rigidity, and durability. They also demonstrate excellent resistance to wear, fatigue, and stress corrosion cracking, making them suitable for demanding marine and industrial applications.
