    What Is 7075 Aluminum? 7075 is a 7xxx-series alloy built around zinc, magnesium, and copper, where the MgZn\u2082 precipitate is the main strengthening phase; it gains strength through precipitation hardening to a level no other common wrought aluminum matches, which puts it in a class of its own for high-load, weight-critical structures.
