A high quality aerospace grade aluminum alloy (6061B) reinforced with 20 vol.% silicon carbide particles which produces a metal matrix composite (MMC). 620XF is manufactured via a powder metallurgy route using a mechanical alloying process to ensure a homogeneous reinforcement distribution, providing a refined grain structure enhancing mechanical properties. The MMC is heat treatable offering high strength and modulus for structural applications and is available in billet, forged and extruded forms.

620XF Advantages:

  • Precision section extrusion using standard dies
  • Reduced wall thickness offering weight saving
  • High stiffness and strength
  • Robust and ductile for damage resistance
  • Good corrosion and fatigue performance
  • Thermally stable
  • Equivalent Materials
