Composite materials are now increasingly coming onto the market. Will aluminium fall behind in the lightweight material mix of the future?
Hofmann: A few years ago, genuine competition did actually emerge, which we in the aluminum industry also encouraged — not least through the Audi project. This ongoing competition among materials is set to continue and set beyond doubt to keep spawning innovations again and again. Moreover, we...
