Kaiser Aluminum manufactures semi-fabricated specialty aluminum mill products, including plate, sheet, coil, and extruded and drawn products, serving aerospace, packaging, general engineering, and automotive markets. The company operates on a metal price-neutral business model in which it purchases primary and recycled aluminum at market prices and generally passes the underlying index cost to customers each month, allowing it to earn profits primarily from the conversion of raw aluminum into finished mill products rather than from price speculation. Revenue comes from four main end markets, with packaging representing the largest segment, and the company invests strategically in manufacturing capacity and efficiency to strengthen its competitive position.
