Aluminium Bahrain B.S.C. (Alba), the world's largest aluminium smelter ex-China, is known for its technological strength and innovative policies. Alba enforces strict environmental guidelines, maintains a high track record for safety, and is widely regarded as one of the top performers on a global scale.

It supports numerous community oriented programmes and social activities that have underlined its status as one of Bahrain's leading industrial organisations that remains committed towards upholding its corporate social responsibilities. Alba's inception marks the beginning of Bahrain's strategy to diversify its economic base and reduce its dependence on oil. The aim was to establish an industry that would provide valuable export earnings, develop the country's resources and create training and employment opportunities for a large number of Bahrainis. Alba was therefore incorporated by Charter in 1968 and officially commenced operations in 1971 as a 120,000 tonnes per annum smelter.

Today, Alba’s production capacity has reached more than 1.5 million metric tonnes per annum of the highest grade aluminium, with products including standard and T-ingots, extrusion billets, rolling slab, properzi ingots, sows, and molten aluminium. Around half of its output is supplied to Bahrain's downstream aluminium industry, with the rest exported to regional and international customers in the Middle East, Europe, Far East, South East Asia, Africa, and Americas.

The Alba plant comprises six reduction lines, three casthouses, four dedicated carbon plants, a 550,000 mtpa coke calcining plant, a water desalination plant, 11 fume treatment plants, a marine terminal and 5 power stations. The plant also features a 13 hectare 'green' oasis, with more than 15,000 trees and shrubs, a fruit and vegetable garden as well as an artificial lake.

Alba's early success established a blueprint for other non-oil industries to follow, including a thriving downstream aluminium industry. Today, Alba is a major contributor to the social, industrial and economic development of the Kingdom of Bahrain, employing over 3,100 people, of whom around 84 percent are Bahrainis.

The entire plant operates to the Environmental Management System standard ISO 14001:2015 and the Occupational Health and Safety Management System ISO 45001:2018. Moreover, the Casthouses, Calciner, and Marketing are also operating to the ISO 9001 Quality Management System. It is worthy to note that Alba was the first metals manufacturing company in Bahrain to receive the major upgrade - 2008 version of ISO 9001.

The company has won a number of awards including the inaugural Shaikh Khalifa bin Salman Al Khalifa Award for Industrial Excellence, the International Millennium Business Award for Environmental Achievement from the United Nations, safety awards from the British Safety Council and The Royal Society for the Prevention of Accidents, and a GCC-wide award for human resources development and nationalisation of the workforce.

The shareholders of Alba are Bahrain Mumtalakat Holding Company (69.38%), SABIC Investment Company (20.62%) and the General Public (10%).​
