Defense & Marine

Sea · Air · Land

Corrosion-resistant, non-magnetic and high-strength alloys for naval, subsea and defense platforms where failure is not an option.

The industry

Defense systems at sea, in the air and on land.

Lebronze Alloys supplies the builders of defense systems at sea, in the air and on land, answering extreme conditions, miniaturization and the utmost level of reliability for both mechanical components and electronics. On the naval side, more than 50 years of seawater-corrosion expertise (with French Navy shipyards since 1982) back our cupronickel and aluminium-bronze ranges.

From seawater circuitry, valve bodies and propulsion to electric connectors, non-magnetic shielding and high-strength interconnect cables, LBA alloys deliver mechanical performance under heavy load and reliable electrical behaviour, with customized materials and treatments where the mission requires.
