As Alcoa Inc. and Arconic Inc.
In 2000, Cordant sold its stake in Howmet to Alcoa, which placed Howmet into its Alcoa Industrial Components unit. In 2004, Howmet was part of a merger that created Alcoa Investment Casting and Forged Products unit. In 2007, Howmet was renamed Alcoa Howmet as a newly formed Alcoa Power and Propulsion unit division.
On November 1, 2016, Alcoa Inc. spun off its bauxite, alumina, and aluminum operations to a new company called Alcoa Corp.[3][4][5][6][7][8] Alcoa Inc. was renamed Arconic Inc.,[9][10][11] and retained the operations in aluminum rolling (excluding the Warrick operations), aluminum plate, precision castings, and aerospace and industrial fasteners.[6][7][8][12][13] Its focus became turning aluminum and other lightweight metals into engineered products such as turbine blades for sectors including aerospace and automotive.[14][15][16]
On January 31, 2017, the hedge fund Elliott Management Corporation launched a proxy contest against Arconic. Elliott publicly called for firing Arconic's CEO, Klaus Kleinfeld, citing the company's lackluster stock performance, missed profit forecasts, and inefficient spending.[17] On April 17, 2017, Kleinfeld resigned as chairman and CEO by mutual agreement with the board of Arconic, after sending an unauthorized letter to Elliott.[18]
On February 8, 2019, Arconic announced that it would split into two separate businesses.[19] Arconic Inc. would be renamed Howmet Aerospace Inc. and a new company, Arconic Corporation, would be set up and spun out. Arconic Corporation will be focused on rolled aluminum products, and Howmet Aerospace will focus on engineered products.[20] The separation was scheduled to become effective on April 1, 2020.[21]
In 2024, during the Gaza war, Howmet's Pittsburgh headquarters were targeted by pro-Palestinian protestors--Howmet produces titanium components used in Lockheed Martin fighter jets that have been sold to Israel.[22]
In December 2025, it was announced that Howmet Aerospace had agreed to acquire Stanley Black & Decker's aerospace business, Consolidated Aerospace Manufacturing, for US$1.8 billion in cash. The transaction was expected to close in the first half of 2026, subject to customary closing conditions.[23]
