Properties:

1. Corrosion Resistance:
• Excellent resistance to corrosion in various environments, including freshwater, seawater, and mildly acidic conditions.
• Resistant to dezincification and stress corrosion cracking.
Mechanical Properties:
• Tensile Strength:Typically around 310-410 MPa.
• Yield Strength: Approximately 100-150 MPa.
• Elongation: Generally around 35-40%, indicating good ductility
• Hardness: Moderate to high hardness, with a typical Brinell hardness number (HB) of around 60-100.
Thermal and Electrical Conductivity:
• Good thermal conductivity, suitable for heat exchangers and other thermal applications.
• Good electrical conductivity, less than pure copper but sufficient for many industrial uses.

Applications:

Plumbing and Heating: Used in plumbing systems, fittings, and valves due to its corrosion resistance and mechanical properties.
Marine Applications: Employed in marine hardware and components due to its excellent resistance to seawater corrosion.
Industrial Applications: Used in various industrial equipment, including heat exchangers, condensers, and piping systems.
Architectural Applications: Utilized in decorative and architectural elements due to its aesthetic appearance and workability.
Electrical Application: Used in electrical connectors and components where good conductivity is required.
