Lebronze alloys

Combining experience and innovation

Lebronze alloys’s DNA: multidisciplinary skills for final applications

LBA Designers

Sustainability, usability, efficiency, toxicity… the challenges to be met in the production of alloys are numerous and diverse. By constantly looking for synergies between raw materials, we improve existing formulas and develop new ones adapted to each function.

LBA Adapters

Based on customer needs, functional specifications, regulatory constraints and precise specifications, we design the custom alloys that best suit you. We analyze all options technically and financially in order to optimize the choice of materials and processes and to reduce the product’s total usage cost.

LBA Manufacturers

Using an integrated production system, we jointly manufacture finished and semi-finished products. Depending on the part to be made and the nature of the metal to be formed, we determine the most appropriate process (forging, casting, stamping, cold stamping…) and ensure the quality of the finished products.

LBA Problem solvers

From R&D to solution implementation, our motivation is to solve your problems. In a collaborative approach, we optimize our processes and materials to meet your most complex needs. Casting close to final dimensions, pre-machined drafts, recycling at the end of life: your requirements shape our solutions.
