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

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

MMC is versatile and can be processed with:

• CNC machining from hipped billet, from forging or extrusion, with customized PCD tools
• Wire EDM

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 drawing, obtaining a greater productivity, quality and definition of details compared to processing with traditional tools in Widia.
