Aero engines

Aero engine parts face many stress challenges: temperatures close to 800°C / 1,475°F, corrosion from gas and humidity, resistance to shock and crack propagation, over several hours and with minimized fuel consumption. Hence the need for the most advanced materials, such as Nickel-based Superalloys and Titanium, and the most demanding techniques, such as open and closed-die forging.

OUR OFFERING

Aubert & Duval supplies the commercial and military aero engines markets with closed-die forgings.Aubert & Duval supplies the commercial and military aviation markets with rotating closed-die forgings, including disks, compressor shafts, turbine shafts, cone shafts and spinners, made from superalloys, titanium, high performance steels or aluminium.

Aubert & Duval contributes to improvements in weight reduction, fuel efficiency, heat resistance and strength, thanks to its innovative materials and expertise in forging.

Aubert & Duval supplies the commercial and military aviation markets with rotating closed-die forgings  including fan disks.

Aubert & Duval is fully committed to its customers’ long-term success and serves major aircraft engine manufacturers worldwide with closed-die forgings, open-die forgings and bars.

For many years, Aubert & Duval has also developed powder metallurgy expertise and provided superalloy billets based on powder metallurgy for rotating engine parts, particularly N18.

With the recent development of 3D printing, Aubert & Duval also offers a wide range of aviation-grade powders for additive manufacturing in superalloys produced by VIM gas atomization.

INNOVATIVE MATERIALS FOR AERO ENGINES

Aubert & Duval constantly seeks new metallurgical solutions in partnership with its customers.
