Lebronze alloys Group was born from the integration of different companies specializing in copper alloys, copper, nickel alloys, aluminium alloys, specialty steels, stainless steels, titanium and nickel superalloys.

Thanks to a multidisciplinary know-how, the Group provides innovative solutions to all major industries such as Aerospace, Oil & Gas, Power, Railway but also in sectors manufacturing smaller equipment and products.

Our 14 production facilities and 1,300 employees manage a unique range of metal processing technologies: continuous and semi-continuous casting, sand casting, die precision chill casting (manual, mechanized and automated), centrifugal casting, extrusion, ring rolling, hot and cold rolling, drawing, open-die forging, hot stamping, closed-die forging, cold forming, machining, non-destructive testing, etc.

The Group’s commitment is to find appropriate and optimized solutions for every sector’s requirements.

We hope that this website allows you to find answers or ideas to support your projects.

We will help you to realize these!

A unique set of capacities in Europe: 

  • A preparation press of 2,500 t with large dimensions (hot extrusion of preforms),
  • Several kinds of furnaces to heat steels, aluminum, copper and nickel alloys and titanium at aerospace quality levels,
  • Tooling design and manufacturing onsite,
  • Internal capacities of machining, thermal treatments and finishing,
  • Non Destructive Testing: ultrasonic testing ; penetrant testing ; 3D dimensional control ; magnetoscopy ; electrical conductivity testing

Examples of products per markets:

  • Energy and electricity: forged parts for wind turbines, pumps and valves for nuclear energy, etc.
  • Offshore and onshore oil & gas: large valve bodies, large pumps, flanges, etc.
  • Construction equipment, cranes, mining, trucks and off-highway: transmission and large pivot shafts, crane parts, spindles, etc
  • Railway: brake discs, hubs, structural parts, etc
  • Defense, naval and marine.

The new 40,000 kgm (400 kJ) double acting drop-hammer will complement to the existing forging capabilities in Custines: another hammer of 16,000 kgm, open-die forging, screw press of 2,500 t, Maxi-Press of 2,500 t. The Custines factory is ISO 9001 and EN 9100 certified.
