Alcoa Corporation, formerly known as Aluminum Company of America, is a leading global producer of aluminum with its headquarters located in Pittsburgh, Pennsylvania, United States. The company has a rich history that dates back over 130 years. Alcoa was founded in 1888 by Charles Martin Hall, who successfully produced aluminum using his newly developed electrolytic process.

This innovation revolutionized the industry, and Alcoa played a pivotal role in the commercialization of aluminum. Over the years, the company diversified its operations, becoming involved in various stages of the aluminum production process, including mining, refining, smelting, and recycling. Alcoa's headquarters in Pittsburgh serves as the central hub for its global operations.

The company operates in four major segments: Bauxite, Alumina, Aluminum, and Cast Products. It primarily focuses on producing value-added products for several end markets, including aerospace, automotive, industrial, packaging, and building and construction. As a global corporation, Alcoa has a significant presence around the world.

It operates in nearly 40 countries and has over 160 locations. The company has several noteworthy subsidiaries, joint ventures, and partnerships. Notable subsidiaries include Ma'aden-Alcoa Joint Venture, a partnership with the Saudi Arabian Mining Company, and Alcoa World Alumina and Chemicals, which operates alumina refineries and aluminum smelters globally.

Alcoa has a strong market position in the global aluminum industry. It has established long-standing customer relationships and is known for its commitment to innovation, quality, and sustainability. The company's global sales reach over 70 countries, and it competes with other major aluminum producers, such as Rio Tinto, Rusal, and Norsk Hydro.

In recent years, Alcoa has undergone significant changes to streamline its operations and focus on its core businesses. In 2016, Alcoa split into two separate publicly traded companies – Alcoa Corporation and Arconic Inc. This separation allowed Alcoa Corporation to solely focus on the mining, refining, and producing of aluminum.

Currently, Alcoa continues to be a leading global aluminum producer. It is committed to sustainable practices and has set targets to reduce its carbon emissions and waste generation. Alcoa remains a key player in the industry, driving innovation and providing high-quality aluminum products to meet the growing global demand
