Copper and copper alloys complex profiles

Special profiles & plates

For decades, Lebronze alloys has been a reference in the designing and manufacturing of rods and wires special profiles for machining, cold heading, and cold forming.

We supply standard profiles (round, square, hexagonal etc.) as well as profiles with complex and asymmetrical shapes.

Our profiles manufacturing processes are fully integrated and include casting, tooling, extrusion, cold-drawing, and heat treatments.


Pre-profile extrusion

Dedicated tooling department

Our Lebronze alloys Germany GmbH plant is specialized in the production of complex profiles. Indeed, our factory is equipped with a dedicated department that handles the design, engineering, and manufacturing of toolings that are used across all production stages.

Near-to-shape extrusion

One of our specialties is pre-profile extrusion. Thanks to this preliminary work, we get closer to the desired final shape right from the hot forming stage.

It is more efficient and cost-effective to produce near-to-shape semi-finished products. Since the profile is nearer to the desired final shape from the earliest production step, less material is used, and fewer scraps are made which is also more ecological.

After the extrusion, our profiles will be undergoing cold-drawing and the adequate heat treatments to obtain the required mechanical properties.

Our special profiles alloys

Our profiles are made from a range of high-quality copper, brass and bronze alloys which guarantees high electrical conductivity combined with optimal properties in tensile strength and mechanical deformation.

Depending on your profiles’ form, we offer different packagings (packets, coil/ring, spool, metal spools, and rods)

Our near-to-shape profiles will reduce any additional machining operations you might have.

The list of copper and copper alloys and capabilities we master for complex profiles manufacturing is described in the following table.
