Arconic separated from Alcoa in 2016 and split again in 2020, with Howmet taking the engineered products: jet engine airfoils cast from nickel superalloys, fastening systems, aluminum wheels for commercial trucks, and forged titanium structures. Engine components are the profit center, sold into both original equipment and the spare parts aftermarket as airlines fly older fleets longer. The business is levered to narrowbody build rates at Boeing and Airbus and to engine flight hours. Headquarters are in Pittsburgh.
