Manufacturing of metal parts for extreme environments

A new standard for aerospace engineering

In the aerospace sector, conventional alloys (titanium, stainless steels, aluminum) are reaching their mechanical, thermal, and tribological limits. Subjected to cryogenic temperatures, absolute vacuum, and the strictest weight-reduction constraints, your systems demand a technological breakthrough.

Vulkalloys® redefine the standards of precision metallurgy, delivering the level of performance that matches the demands of these cutting-edge sectors.

Actuators and Compliant Mechanisms

Manufacturing of metal parts with extreme elasticity for friction-free, jam-free spatial deployment

Deploying solar panels, reflectors, and satellite antennas tolerates no risk of imprecision or mechanical failure. By replacing traditional pivot joints with the elastic deformation of the material itself, Vulkalloys® compliant mechanisms and flexure hinges secure the reliability of spacecraft actuators.

Unprecedented deformation range: an elastic coefficient up to 10 times higher than conventional crystalline alloys, enabling the design of long-stroke flexible structures.
Cryogenic reliability: mechanical performance and elasticity retained at extremely low temperatures (cryogenic environments, spacecraft shadow zones)
Precision and repeatability: Your components deform and return to their original shape with no residual deformation, ensuring durable, predictable behavior cycle after cycle.

Transmission Systems and Gearing

Ultra-resistant mechanical transmissions operable without lubricant

Vulkalloys® gears and mechanical transmissions enable extended dry running while guaranteeing exceptional geometric precision. An unprecedented innovation in manufacturing of metal parts.

Dry contact with high resistance : remarkable behavior under unlubricated contact, with an optimized coefficient of friction and minimal wear.
For high micro-mechanical reliability: superior wear resistance for durable, high-performance micro-gears.
Dimensional precision and surface finish: precision parts with a superior surface finish achieved directly through the casting process.

Connection and Interface Systems

Manufacturing of metal parts with miniaturization and weight reduction at the core of complete onboard systems.

Featured within a complete mechanical system, Vulkalloys® fasteners, seals, flexure springs, hinges, and connectors deliver tangible gains on every component. They combine maximum compactness with extreme durability under severe environments. Which makes the manufacturing of metal parts more demanding than ever.

Extended maintenance-free service life: excellent mechanical and tribological performance in dry or corrosive environments over very long mission durations.
Miniaturization and weight reduction: the exceptional mechanical properties allow for reduced thicknesses, lowering overall onboard mass and adapting to the tightest spaces.
Perfect fit with zero play: micrometric manufacturing tolerances for connectors and mechanical joints that remain stable under vibration.

Our amorphous metallurgy engineering teams support you from design through manufacturing of your high-precision parts.
