Properties:

1. Corrosion Resistance:
• Good resistance to corrosion in various environments, including freshwater and mildly acidic conditions.
• Resistance to dezincification and stress corrosion cracking.
Mechanical Properties:
• Tensile Strength:Typically around 300-550 MPa.
• Yield Strength: Approximately 100-200 MPa.
• Elongation: Generally around 25-40%, indicating good ductility
• Hardness: Moderate hardness, with a typical Brinell hardness number (HB) of around 80-110.
Thermal and Electrical Conductivity:
• Good thermal conductivity, making it suitable for heat exchanger and other thermal applications.
• Moderate 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.
• Industrial Applications: Employed in various industrial equipment, including marine hardware, fasteners, and components requiring good mechanical strength.
• Electrical Applications: Used in electrical connectors and components where moderate conductivity is sufficient.
• Architectural Applications: Utilized in decorative and architectural elements due to its aesthetic appearance and workability.
