Kaiser Aluminum an American aluminum producer is a spinoff from Kaiser Aluminum and Chemicals Corporation which came to be when common stock was offered in Permanente Metals Corporation and Permanente Metals Corporation's name was changed to Kaiser Aluminum and Chemicals Corporation. Henry J. Kaiser's corporation entered the aluminum business by leasing, then purchasing three government-owned aluminum facilities in Washington state. These were the primary reduction plants at Mead and Tacoma, and the rolling mill at Trentwood. The company grew to be a vertically integrated aluminum producer. Kaiser currently owns 12 fabricating plants that can produce more than 400,000,000 pounds (180,000 long tons) of aluminum annually. The company also owns a 49 percent interest in an aluminum smelter in Wales. The North American plants produce approximately 500,000,000 pounds (220,000 long tons) per year of value-added sheet, plate, extrusions, forgings, rod, bar, and tube. Kaiser previously owned a subsidiary that developed real estate, including Rancho California, California.
