Aluminium-bronze components for
Marine & Hydraulic applications
A proven alloy for marine and hydraulic environments
Aluminium bronze is widely used for components operating in marine, hydraulic and water-related environments.
Its excellent corrosion resistance, especially in humid conditions and seawater exposure, combined with strong mechanical properties, makes it particularly suitable for demanding industrial applications.
Davergne designs and manufactures aluminium bronze cast components for water, fluid handling and hydraulic systems, with decades of experience in durable technical castings.
Thousands of Davergne components are currently operating in marine, hydraulic and industrial installations.
A strategic market driven by corrosive environments
Components designed for water and fluid-related applications
Components designed for humid and corrosive environments
CuAl10Fe2 aluminium bronze is particularly suited for components exposed to mechanical loads and aggressive or humid environments.
It is commonly used for equipment operating in contact with water, within hydraulic, industrial and marine installations.
It provides:
- excellent corrosion resistance
- very good seawater performance
- high mechanical strength
- long-term dimensional stability
These properties make it an ideal material for components operating under demanding conditions, especially in marine and hydraulic applications.
Examples of practical applications
In marine environments, contact between stainless steel components can lead to galling and seizure.
Aluminium bronze helps prevent this phenomenon, making it particularly suitable for salt-exposed mechanical components such as marine turnbuckles.
Aluminium bronze is also widely used for components subjected to high hydraulic pressures, including valves and firefighting network fittings.
Its mechanical strength and service stability make it suitable for applications where reliability and operational safety are critical.
For components exposed to high mechanical stresses, such as towing handles for inflatable boats, the ability of the material to deform without sudden fracture is a major advantage.
This behaviour contributes to user safety and long-term durability.
Finally, aluminium bronze contains neither zinc nor lead, making it particularly suitable for water treatment applications.
It is used for components in direct contact with water, including UV treatment system bases and pumping equipment where material compatibility and durability are essential.

Marine and hydraulic applications of aluminium bronze
Davergne aluminium bronze components are used in applications where corrosion resistance and durability in humid environments are essential.
They are integrated into various systems and equipment, including:
- industrial valves and flow control systems
- water treatment equipment
- hydraulic installations and equipment
- marine and harbour infrastructure components
- safety systems such as firefighting networks and valves
These components play a key role in installation reliability and operational continuity.
Their resistance to corrosion and demanding environments ensures long-term performance throughout the equipment life cycle.
