Le Bronze Industriel started and developed the internal production of copper nickel for seawater corrosion resistance in collaboration with French Navy shipyards DCN in 1982.

Through our brand new facilities and fully integrated production process, from raw material through smelting, casting extrusion, drawing, forging, forming, stamping and machining, we manufacture the complete range of pipes, fittings, flanges covering all various international standards or dedicated specifications applicable to copper nickel products.

We provide seamless and/or welded pipes and BW fittings, hot stamped, forged and machined fittings and flanges from 1⁄4” till 48” in order to cover the complete package required for whatever naval project.

As a leader, we are constantly improving our service by keeping large inventories of finished products, offering either small or large quantities to our customers.

In addition to copper nickel for sea water systems, our range of aluminium bronzes and nickel copper alloys are widely being used for specific military applications such as torpedo launching systems, subsea missile launchers, nuclear propulsion vacuum systems for which we manufacture semi-finished and fully engineered designed products under military licenses.

Finally, we can offer die-forged parts in special steels.

Nowadays Lebronze alloys Group is a referenced and preferred supplier with worldwide major navy or commercial shipyards, ship-owners, naval architects and engineering companies.
