|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
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.
