TIN BRONZE

ASTM B30 C92600:

ASTM standard specifying the composition and mechanical properties for tin bronze alloys.

BS1400 (PB1):

British Standard specifying the requirements for high-tin bronze alloys, often referred to as phosphor bronzes.

BS 1400 GL:

British Standard specifying the composition and mechanical properties for various grades of bronze alloys.

PB102:

A specific grade of tin bronze known for its excellent wear resistance and high mechanical strength.

Properties:

1. Corrosion Resistance:
• Excellent resistance to corrosion in a wide range of environments, including marine and industrial applications.
• Particularly resistant to dezincification and stress corrosion cracking.
Mechanical Properties:
• Tensile Strength:Typically around 300-600 MPa.
• Yield Strength: Approximately 150-250 MPa.
• Elongation: Generally around 10-30%, indicating good ductility
• Hardness: Moderate hardness, with a typical Brinell hardness number (HB) of around 60-100.
Wear Resistance:
• High wear resistance, making it suitable for applications involving friction and wear.
• Good anti-galling properties, ideal for bearings and bushings.
Machinability:
• Good machinability, allowing for precise manufacturing and machining of components.
• Can be easily cast, forged, and worked. .
Thermal and Electrical Conductivity:
• Good thermal conductivity, suitable for heat exchange applications.
• Moderate electrical conductivity, sufficient for many industrial uses but lower than pure copper.

Applications:

Bearings and Bushings: Extensively used in the production of bearings and bushings due to its high wear resistance and good anti-friction properties.
Marine Hardware: Commonly used in marine hardware such as propellers, pumps, and valves due to its excellent corrosion resistance.
Gears and Worm Wheels: Suitable for gears and worm wheels where high strength and wear resistance are required.
Architectural Applications: Used in architectural elements such as statues, plaques, and decorative items due to its aesthetic appearance and good corrosion resistance.
Industrial Equipment: Suitable for various industrial equipment parts, including valve bodies, pump components, and connectors.
