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).
Our specialty materials, for instance Hardiall, Hardibron and K5B are used in: Measurement components during drilling (MWD), Shock absorber collars, Turbine bearing rings, Pressure protection chambers instrumentation gamma probes, x-ray,battery packs, Blow out preventer (BOP) bearings and seals, Mud motor pump bearings, Valve Guides, Subsea christmas tree, Actuator stem, Wellhead controls, Sealed actuator valve guides, Actuator Nuts and Rods, Bearings and thrust washers horizontal rotary drilling tools, Valves Bonnets,Stems ,Seals, Gate, Connectors and hydraulic components wellhead manifolds, Hydraulic connectors stabplates blowout preventer, Fluid hydraulic connectors and underwater tools for radio-controlled underwater vehicles (ROV), Shut-off rod and valve flap, Tri-cone and Reamers rotary steerable horizontal directional drilling (HDD) thrust washers and bushings
On land, we offer solutions for: Artificial pumping valve stem ring fittings, Artificial pumping rod guide bushing couplings.
