Kaiser Aluminum Corp
A maker of specialty aluminum mill products for demanding jobs, from aircraft parts and beverage can stock to automotive extrusions and industrial components. Founded in 1946 by the industrialist Henry J. Kaiser, it began as Permanente Metals Corporation, a name borrowed from a California creek that flows year-round — "permanent" water for early Spanish ranches. Its rolling mill in Trentwood, Washington, and smelters in Mead and Tacoma were leased from the government after World War II.
