The resistant metal
Compared with other copper alloys, the higher strength of the aluminium-bronzes is combined with excellent corrosion resistance under a wide range of service conditions.
Aluminium-bronzes are the most tarnish-resistant copper alloys and show no serious deterioration in appearance and no significant loss of mechanical properties on exposure to most atmospheric conditions. Aluminium-bronzes are very resistant to corrosion by sea water and probably find more use in sea water service than in any other environment.
This material is quite outstanding in resistance to corrosion fatigue in sea water, being much superior to high tensile brass or to stainless steels.
Manganese aluminium-bronze, which is also used for large propellers, also has high corrosion fatigue strength though somewhat inferior to nickel aluminium-bronze.
