Project partners have developed a new copper matrix composite with less thermal expansion and more resitance to friction and lower machining requirements.
 
This project has developed a new copper matrix composite that has improved properties compared to that of a conventional non-reinforced matrix. There is less thermal expansion and more resistance to friction. The new composite will be used to produce components such as crowns with reductors for lifts and crowns with syncronisms for vehicles.

The partners have also developed a new processing method using squeeze casting technology. This is a cleaner process than traditional centrifugal casting, as there are no metal projections or pollutant residues. Working conditions of operatives will therefore be improved.

Lower machining requirements are expected to lead to a 10% reduction in direct production costs and a 30% reduction in energy use. There should be a 2% decrease in the rejection of components with defects and generally less scrap metal.

Close involvement of SMEs has ensured the success of the project. One of them, WISCO, is currently involved in a new private project to bring the technology to market.
