Typical applications

Thanks to its excellent physical and mechanical properties, including corrosion resistance to (warm) seawater, CuAl10Ni5Fe4 is used in a wide range of demanding applications. The following industries and application contexts are therefore only examples:

Chemical industry
Maritime applications
Mechanical engineering
Toolmaking
Aerospace
Hydraulics
Valves and fittings

The material is characterised by high strength values even at elevated temperatures of up to approximately 400 °C. It shows good corrosion resistance to neutral and acidic aqueous media as well as seawater and a good resistance to scaling, erosion and cavitation.

CuAl10Ni5Fe4 has very high wear resistance. Good sliding properties are achieved when paired with mating materials that have hard surfaces and with proper lubrication.
