Boeing has awarded a new contract to Montana Aerospace for the manufacturing of wing stringers for its 767 aircraft.

Serial production of the stringers will commence following an extrusion manufacturing qualification process at Montana Aerospace’s state-of-the-art facilities in Satu Mare, Romania, which is expected to be completed by mid-2024.

Montana’s Universal Alloy Corporation division will supply stringers for the airplane wing using 7000 Series aluminium alloy. The extrusion of the stringers will take place at the Satu Mare facility, which houses Europe‘s largest diameter extrusion “Heavy Press” dedicated to aerospace components.

The components will undergo further processing at the nearby Baia Mare facility to be transformed into ready-to-install components, benefitting from the unique one-stop-shop vertical integration process that Montana Aerospace companies are renowned for.

“We are proud to collaborate with Boeing on this project and further grow our long-standing relationship,” said Paul Andreucci, chief commercial officer of Montana Aerospace Aerostructures. “This work package for our new facility in Romania reaffirms the quality of our products and the efficiency of our manufacturing processes. And we are confident that we will meet Boeing‘s expectations.”

Kai Arndt, Co-CEO of Montana Aerospace, added “Today, we have seven extrusion plants globally with over 25 presses, including large-diameter presses for manufacturing aluminium structural components of up to 30m in length. Two of these specialized presses are located in our US facilities, and another large-diameter press was built and commissioned in just 18 months, being the first of its kind in Europe.”

The stringers are made from specialized aluminium alloys that offer an optimal combination of lightweight design, excellent corrosion resistance, high strength, and flexibility. The use of 7000 Series alloys provides the stringers with exceptional strength and stability, according to Montana Aerospace.
