Welcome

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!

K5B® is a wrought copper nickel aluminum alloy CuNi14Al3 (NES835) designed for high strength applications in seawater environment. It is non-magnetic and resists mechanical wear, galling, stress relaxation, corrosion and erosion.

It is easily machined into complex components, whilst being environmentally friendly being both lead and beryllium free.

K5B® is used within the oil & gas industry thanks to its outstanding physical and mechanical properties in many varied components.

Lebronze alloys has developed a full range of Copper Nickel Aluminum matching the Oil & Gas industry stringent requirements.

  • High strength & Toughness
  • Outstanding resistance to marine corrosion & erosion
  • Excellent wear resistance
  • Good anti-fouling properties
  • Good machinability
  • Excellent galling resistance especially with stainless steels
  • Good thermal properties
  • No Hydrogen embrittlement
  • Low magnetic permeability
  • Galvanic compatibility with other copper alloys and stainless steel
  • High performance at both elevated and sub-zero temperatures -193 °F up to 572 °F
  • Dimensional stability

Lebronze Alloys manufacturing process for K5B® is fully integrated: internal processes include casting, hot and cold working stage, heat treatment and non-destructive testing. Being fully integrated ensures reactivity and complete traceability.
