Kaiser Aluminum Corporation announced that its Board of Directors has approved $14 million in additional investments to enhance and expand extrusion capabilities at its Tulsa, Okla., and Sherman, Texas, facilities and deploy “future state” upgrades to the casting complex at its Trentwood (Spokane, Wash.) facility. The investment at the Trentwood facility will improve energy efficiency in its casting process, reducing natural gas consumption per pound cast. The improvements will incorporate a state-of-the-art furnace and combustion system design, utilizing environmentally friendly and energy-efficient regenerative burners and allowing for reduced material waste.

The investments expand Kaiser Select capabilities at Tulsa to produce automotive extrusions. Equipment upgrades at Sherman will expand capabilities to produce Kaiser Select products. The upgrades will also increase efficiency and capacity at Sherman, which produces extruded products for ground transportation and industrial applications.
