SupremEX® 640XA MMC is a high quality, aerospace-grade aluminum alloy (6061B) reinforced with 40 vol.% silicon carbide particles. This composite material is manufactured via powder metallurgy using a mechanical alloying process to ensure a homogeneous reinforcement distribution, providing a refined grain structure and enhanced mechanical properties. SupremEX 640XA MMC is heat treatable, offering high strength and modulus with a CTE match to nickel plating (13 ppm/°C). This material is excellent for lightweight, high-stability structural applications. Designation: 6061B/SiC/40p (3 µm). Benefits - Weight saving
- Static strength comparable to high-strength Al alloys
- Exceptional specific stiffness for increased component stiffness
- High fatigue resistance
- Refined, homogeneous and stable microstructure
- Excellent hardness, wear resistance and low friction characteristics
- Good machinability using high-speed machining techniques
- Superior thermal stability, with CTE match to Ni plating
