The researchers showcased the parts and other auto developments the Hannover Messe fair, which took place from 4-8 April in Hannover, Germany.

 The car door weighs around 4.7 kg (over 10 lb), while the same version in steel weighs 10.7 kg (23.5 lbs). “Magnesium is available in large quantities worldwide, it can be moulded, and for similar structures – a car door, for instance – it has virtually the same properties as steel. For example, it has a comparable rigidity,” says Sören Scheffler, group manager at Fraunhofer Institute for Machine Tools and Forming Technology IWU. “We have developed specific moulding technologies for wrought magnesium alloys. This makes the lightweight material available for future use in series production of car bodies.”
 
The researchers have also developed a slide-ground tumbled alloy wheel rim and looked at ways to improve the process of slide-grinding and tumbling in which the wheel rim is moved through a fill of abrasive media moving with a particular frequency.
