Bonjour !
Ca bouge côté Aluminium, chez Airbus ....1,4 billionsde $ sur on ne sait quelle période, c'est énorme !
Pour les A320, les peaux inférieures des ailes, quel alliage ... on ne sait pas !
Alors, pas de programme d'allégements sur le A320 ??
Le A350, c'est attendu !
Et le A380 devrait maigrir encore !
Le A330 pas mentionné sur ce coup !
C'est bien !
Alcoa ... ce n'est pas Constellium ...donc si on l'additionne au contrat Constellium, ça commence à faire une belle montagne d'Al-Li à écouler sur les avions
d'Airbus ... qui reste trés discret sur le sujet !

Alcoa announced on July 11 at the Farnborough
International Airshow (Farnborough, U.K.) that it has signed new
multi-year supply agreements with Airbus for Alcoa’s leading aerospace

current, advanced-generation and aluminum lithium alloys. Terms were
not disclosed, but the agreements have a value of approximately $1.4
billion (USD) over their life.
Alcoa’s leading aluminum solutions
will be used across virtually all Airbus commercial programs and
includes new
lower wing skins on the A320; several aluminum lithium
applications on the A350 and A380, including the largest extruded lower
wing stringers for the A380; as well as the largest wing skins and
fuselage panels for the A380 and structural plate for the A350.Alcoa’s
hard alloy extruded products, including rod, drawn tubing and extruded
shapes for wing stringers and floor structures, will be supplied from
the company’s plants in Lafayette, Ind., and Halethorpe in Baltimore,
Md. in the U.S., and Hannover in Germany. Alcoa flat rolled products
will be supplied from the company’s plants in Davenport, Iowa in the

lithium to support the global Alcoa aerospace supply chain.
