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!

K7 is a wrought copper nickel aluminum alloy CuNi14Al3Fe1 (LN 9468 and WL 2.1504) designed for high strength and high reliability applications. It is non-magnetic and resists mechanical wear, galling and marine corrosion.

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

K7 is used within the aerospace 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 Aerospace industry stringent requirements.

  • High mechanical properties
  • High ductility
  • Outstanding resistance to corrosion & erosion
  • Excellent wear and galling
  • Resistance
  • Good machinability
  • Good thermal properties
  • Good impact resistance
  • No sparks on impact
  • Strictly non-magnetic
  • Stable performance at both elevated and sub-zero temperatures -193 °F up to 572°F
  • Dimensional stability

Lebronze Alloys manufacturing process for K7 is fully integrated : internal processes include casting, hot and cold working, heat treatment and non-destructive testing. Being fully integrated ensures reactivity and complete traceability.
