Le procédé COBAPRESS : exemples d'applications automobiles : Les matériaux nouveaux de l'automobile

COBAPRESS is a process to make light-metal components, by forging cast-aluminium roughs. The parts obtained have very precise dimensions and a compact metallurgical structure; the mechanical properties are better and less seattered than with the conventional molding process. The Peugeot 406 in the first car equipped with a COBA rear axle component. The weight reduction verous cast iron has been 50 % and the economic trade-off is positive.
