Description

SupremEX® 640XA is an aerospace grade metal matrix composite (MMC) based on an aluminum alloy (6061B) with a reinforcing phase of 40% silicon carbide.


640XA is produced powder metallurgically by mechanical mixing. This results in a fine grain structure, which improves the mechanical properties.


SupremEX composites are hardenable and offer high strength and a high modulus of elasticity, making them ideal for Structural components.


Advantages of 640XA:


  • Weight saving
  • Static strength comparable to that of high-strength aluminium alloys
  • High strength
  • High fatigue resistance
  • Good friction & abrasion properties
  • Good machinability
  • Equivalent Materials
