Germany’s Newalu will supply heat-treated and ready-to-install aluminum components to Lucid Motors, a U.S. manufacturer of electric cars.

The heat treatment adds strength and ductility to the aluminum, which makes it suitable for use as a substitute for steel. The body parts will be sent from a large German foundry to Newalu for finishing. Production of the Lucid Air e-limousine is scheduled to begin before the end of 2021 at the company’s new facility in Casa Grande, Ariz.
