The 206 T7 aluminum alloy
  • The aluminum 206 alloy with a T7 Heat Treat is a high strength, high ductility alloy that can easily meet the mechanical requirements of the brake pedal.
  • The copper content in the 206 alloy is high enough to cause a potential corrosion and pitting problem, which would require an additional protective coating on the pedal.
  • The alloy has enough fluidity to fill the long thin geometry of the mold. But it is susceptible to “hot tearing” which would reduce production yield. An increased possibility of “hot tearing” will require 100% non-destructive inspection of the brake pedal castings.
  • Overall, the 206 T7aluminum alloy exceeds the mechanical requirements, but falls short on corrosion resistance and castability.
