Shipbuilding
The shipbuilding industry can cover a veariety of industrial activities which includes of course building civil ships (liners, container carriers or various transportation vessels) but also Offshore rigs or tidal turbines (Renewable marine energies). What all these industries have in commun is that they face seawater corrosion issues . Over the years, corrosion can dammage the various mechanical components used for propulsion, fluid handling, energy generation, ballast water treatment systems…) which can create unwanted downtime or extra maintenance spendings.
NAB alloys (aluminium bronze or Nickel Aluminium Bronze) are copper bases alloys developped to face seawater corrosion issues and can be found in several applications :
CPP or FPP hubs, Blades, Propellers, Bearings…
Valves, pumps, filters, UV Reactor Bodies…
Heat Exchangers, Roller Bearing Cages
In the most of the above projects, besides core casting competences, approvals from major worldwide classifications societies are requested such as : BV, RMRS, DNVGL , RINA…
Aluminium Bronze
Aluminium bronze is available under various formats to meet the various application requirements :
Sand casting for complexe parts
Centrifugal casting for revolution rotatting aprts
Plates for welded construction needs
Billets and Bars for full part machining
Forgings
