SHELLCAST is working with High-strength
Aluminum Casting Alloy A205

A205 is the strongest cast aluminum alloy currently available and is producing exceptional results in a number of areas.

* Some limitations may apply, depending on overall size, geometry and
  wall thickness.

Benefits of A205

  • Reduces defects traditionally associated with high-strength 200-series copper alloys,
  • Elimination of hot tearing or segregation defects common in 200-series alloys,
  • Improved resistance to stress corrosion cracking,
  • Improved compositional and mechanical properties,
  • Exceptional fatigue properties,
  • Improved properties at elevated temperatures over traditional cast alloys (400F+),
  • Elimination of segregation issues in large sections,
  • Elimination of aluminum copper alloy castability and welding related issues,
  • Fluidity comparable to aluminum silicon alloys,
  • Reduction of shrinkage or porosity.
