## History

### Before Alcoa acquisition

Howmet's roots go back to 1926, when Austenal, a company that manufactured materials for dental appliances, was founded. Its founders, Reiner Erdle and Charles Prange, worked to improve investment chrome base castings using two separate investments: The first coating, named "protective coat", gives a smooth finish. It was smothered with alcohol binder investment to obtain a correct expansion. This technology replaced gold alloy with [vitallium](/source/Vitallium) and was popular during the [Great Depression](/source/Great_Depression).

During the 1930s, Austenal expanded into aircraft engine [superchargers](/source/Superchargers) with superior castings when [General Electric](/source/General_Electric) asked for help to improve manufacturing practices for wartime production demands.

In 1958, Howe Sound Company, a metals and mining business, acquired Austenal. In 1959, Howe acquired Michigan Steel Casting Co. (MISCO), which provided the monolithic shell process. This process uses a [ceramic shell](/source/Ceramic_shell_casting) with thin, strong walls to increase control of the solidification process and produce a sounder [casting](/source/Casting).

Howe became Howmet in 1965, marking a transition from a mining company to a manufacturer of precision metal products. Howmet, in turn, was purchased in 1975 by [Pechiney](/source/Pechiney), a multinational aluminum company. In 1989, Pechiney purchased the Cercast group of companies, bringing Howmet into the aluminum casting industry.

In 1995, Pechiney sold Howmet to a joint venture between [Thiokol](/source/Thiokol) and [The Carlyle Group](/source/The_Carlyle_Group). By late 1997, the ownership structure of Howmet had become Thiokol, with 62% ownership, Carlyle 23%, and the public 15%. In 1998, Thiokol changed its name to Cordant Technologies Inc.; by February 1999, Cordant owned 84.7% of Howmet.

### As Alcoa Inc. and Arconic Inc.

In 2000, Cordant sold its stake in Howmet to [Alcoa](/source/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](/source/Bauxite), [alumina](/source/Alumina), and aluminum operations to a new company called [Alcoa Corp.](/source/Alcoa)[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](/source/Turbine) blades for sectors including aerospace and automotive.[14][15][16]

On January 31, 2017, the hedge fund [Elliott Management Corporation](/source/Elliott_Management_Corporation) launched a [proxy contest](/source/Proxy_contest) against Arconic. Elliott publicly called for firing Arconic's CEO, [Klaus Kleinfeld](/source/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](/source/Arconic), 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](/source/Gaza_war), Howmet's Pittsburgh headquarters were targeted by pro-Palestinian protestors--Howmet produces titanium components used in [Lockheed Martin](/source/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](/source/Stanley_Black_%26_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]
