3 S ince the dawn of the 20th century, Aubert & Duval has been manufacturing products for the most stringent industries: aerospace, power generation, nuclear. Propellant tanks, engines, boosters, structural parts... everywhere Aubert & Duval contributes to the safety of launchers and to the life of spacecraft. For more than 30 years, Aubert & Duval has been proud to face up to the technological challenges of space industry with our customers, starting with the Ariane 4 launchers and continuing with the new generation of spacecraft. Equipment With full vertical integration from melting to remelting, powder atomization, hot converting and machining (rough machining through to near-net-shape parts), Aubert & Duval offers wide-ranging cutting edge capabilities for launch vehicles, satellites and other spacecrafts: structure and propulsion parts, helium tanks, components and fasteners. We have also put in place over many years dedicated skills and modern simulation capabilities to co-design and re-engineer metallurgical solutions in close cooperation with the main original equipment manufacturers. Today, we are leveraging this knowledge to help our customers in their strategic projects, from R&D to industrialscale production, providing high-value metallurgical solutions with close technical support.. MELTING Melting furnaces (EAF, AOD, VOD) up to 60 tons Vacuum Induction Melting (VIM) up to 20 tons tanium Plasma Arc Meting furnace (PAM-CHR) Remelting furnaces (ESR, VAR) up to 30 tons. POWDER METALLURGY Atomization (Air, VIM). FORGING Open-die forging presses from 1,500 to 10,000 tons Closed-die forging presses from 4,500 to 65,000 tons. ROLLING MILL mm diameter bars. HEAT TREATMENT Solution and ageing furnaces Horizontal and vertical quenching equipment. TESTING Immersion UT up to 13 tons (28,000 lbs) Automated contact UT up to 20 tons Let s take up the new Space challenges together! As a specialist in upscale metallurgy Aubert & Duval operates several closed-die forging facilities, such as its 22,000 MT, 40,000 MT and 65,000 MT hydraulic presses. Closed-die forging is the process of forming complex-shaped parts from a metal semi-product between two engraved tools (dies) by pressing with a closed-die forging press. Certifications and specifications In addition to general certifications (ISO 9001, ISO 14001, ISO 18001), our Service Center is certified to the most stringent industry specific standards. 2 # 3
