Aluminium bronzes, such as CC333G (CuAl10Fe5Ni5-C) and CC331G (CuAl10Fe2-C), are highly valued for their exceptional mechanical properties, corrosion resistance, and wear resistance. These alloys are particularly suitable for demanding applications, including bearing bushings, plate grooves, and other bronze parts.

Key Properties of Aluminium Bronzes:

1. High Hardness and Strength:
   Aluminium bronzes are harder and stronger than many other bronze alloys, making them ideal for heavy-duty applications.
2. Excellent Corrosion Resistance:
   These alloys are highly resistant to corrosion, especially in marine and saline environments, due to the formation of a protective aluminium oxide layer.
3. Wear Resistance:
   Their wear resistance makes them suitable for components subjected to friction and abrasion, such as bearings and bushings.
4. Good Machinability:
   While they are harder than other bronzes, they can still be machined to precise tolerances.
5. Thermal and Electrical Conductivity:
   Aluminium bronzes have moderate thermal and electrical conductivity, making them useful in certain industrial applications.
6. Resistance to Deformation:
   They maintain their shape and strength under high loads and temperatures.

Applications of Aluminium Bronzes:

1. Bearing Bushings:
   Aluminium bronzes are widely used in bearing bushings due to their ability to withstand high loads, resist wear, and operate in corrosive environments.
2. Plate Grooves:
   These alloys are used in plate grooves where resistance to wear and corrosion is critical, such as in marine equipment or heavy machinery.
3. Marine Components:
   Their excellent corrosion resistance makes them ideal for marine applications, including propellers, pumps, and valves.
4. Industrial Machinery:
   Aluminium bronzes are used in gears, nuts, bolts, and other components that require high strength and durability.
