Microstructure of Cast and Wrought Aluminum Alloys

ALUMINUM AND ITS ALLOYS

  • Cast vs.Wrought
  • Heat Treatable (PH) vs. Non-heat Treatable
  • Non-heat Treatable – Strengthen by ColdWork
  • Strengthen by Alloying

CAST ALUMINUM ALLOYS

  • Silicon is Major Alloying Element
  • Silicon Improves Fluidity
  • Near-Eutectic Compositions - for Die Casting
  • Refine Eutectic by Adding Sodium (shifts eutectic to about 14%Si)
  • Add Copper to Permit Heat Treatment
