or Innovative Automotive Engineering
Modern automotive engineering today is oriented at safety, energy efficiency and economy. But
luxury and driving pleasure should not be neglected in the car design either. As the number of
components is growing and their functional complexity increases, high performance materials
such as high strength and enduring metals are gaining more and more importance in part design for car manufacturers and their suppliers. By using MIM technology, engineers take advantage of a freedom of design that so far was only applicable to plastics.
The following lists of materials provide an overview of the MIM materials that are used today in
automotive engineering.
