Home | Products | Aluminium Bronzes
Aluminium bronzes are composed of copper and aluminium to which we add simultaneously iron to improve some mechanical characteristics and to obtain a finer grain, nickel to increase the corrosion resistance and manganese to facilitate the casting process.
These alloys also have a good aptitude for friction, machinabilty and cold / hot working depending on the alloys.
They are widely used in aerospace and marine industries. Applications include also electrical and heating systems, valves and fittings, crews and bolts...
