Aluminium bronze casting foundry for engineered components

As a specialist of large size aluminium bronze castings for engineered components, our capabilities enable us to cast any technical component up to 15t To in our Rouen plant and 50 To in our Nantes plant.

Aluminium bronze, or NAB, are alloys including copper-aluminium-nickel and which are primarily documented in EN 1982 and ASTM/ASME B148 standards. NAB have primarily been developped to face sea water corrosion issues but can also be used in various chemical industrial applications where corrosion is a main challenge.

EN 1982-CC333G and ASTM B148-C95800 Nickel Aluminium Bronze alloys are widely used in fields such as ship propulsion, pumps, valves and heat exchangers. Some more specific and proprietary NAB alloys exist such as Inoxyda 53AMA for low magnetic permeability applications or Inoxyda154 for high mechanical characteristics required by engineers. The Inoxyda90 grade has been specifically developped to meet chemical composition and mechanical charateristics of ASTM B171 C63000, an aluminium bronze dedicated to pressure vessels and heat exchangers.

Aluminium bronze alloys (NAB) are available under different forms to meet requirements of engineered components : sand castings, centrifugal castings, continuous castings (for machining or forging purposes) as well as plates from 5 to 20mm thickness. All these solutions are available within the LBI group (Les Bronzes d’Industrie ( www.lbi.fr)
