The production of MMC components is one of the main activity of CRP Technology.

Standard materials connected to motorsport is AMC225xe: 2124 aerospace Aluminium alloys reinforced with particles of carbide of silicon (2-3 micron) at 25%.

MMC is versatile and can be processed with:

• CNC machining from hipped billet, from forging or extrusion, with customized PCD tools
• wire electro-erosion

The advantages of Metal Matrix are:

• considerable weight saving (density 2.88 g/cm3)
• stiffness (elastic modulus 115 GPa)
• great resistance to stress
• excellent behaviour under temperature

The industry of F1 uses MMC Aluminium thanks to its mere features of lightness and higher performances.

CRP Technology has started to process these composites in 2000 focusing its attention on the study and development of more suitable tools for the processing.
The metal-based material is highly abrasive and cannot be processed with traditional tools in hard sintered metal (Widia). For this reason CRP Technology has developed and used PCD tools (Polycrystalline Diamond) customized according to CRP draw, obtained a greater productivity, quality and definitions of details compared processing with traditional tools in Widia.
