A long-time expert in Oil & Gas and Marine systems.

Lebronze alloys has been supplying copper alloys semi-finished end finished products for seawater cor­rosion resistance for more than 50 years. Le Bronze Industriel started and developed the internal production of copper nickel in collaboration with French Navy shipyards DCN in 1982. Lebronze alloys Group is a referenced and preferred supplier with worldwide major navy or commercial shipyards, ship-owners, naval architects and engineering companies.

We have been developing and improving our expertise in Oil & Gas and Marine applications, with copper nickel alloys, copper silicon alloys for oil deep-sea measurement applications (seawater corrosion and friction resistance), copper beryllium alloys for seismic acquisition equipment (seawater corrosion and high strength/elongation re­sistance), and even copper cobalt alloys for Oil & Gas drilling in Offshore industries, whilst also focusing on machined components in Nickel Aluminium Bronze (in BOP for example).
