David, another KMU question, progressing from from 101 to 201......
Basically, the reasons behind a forged aluminum product vs. machined, and the choice of aluminum, heat treat etc. Such as:
" Profil wheels are forged from 6061-T6 aluminum alloy; this aircraft-grade aluminum is heat treated for a higher yield strength than your typical aluminum wheel. This allows us to create stronger, more stable wheels, while maintaining a low weight. "
