7075 Al. Made using 3D forging. The process
lets us forge pieces both externally and internally
simultaneously, which creates less overall
stress on the material being forged. This
creates a finished piece that is significantly
stronger than a one piece that has been
forged and then machined or drilled.

Here's a quick comparison on Al difference...
