5052 Aluminum

7075 is an aluminum alloy, with zinc as the primary alloying element. It is one of the strongest aluminum alloys comparable to many steels, and has good fatigue strength and average machinability. 7075 was specifically designed for aircraft frames because of its strength somewhat greater than steel while maintaining the light weight of aluminum.

Popularly known as “the aircraft alloy”, 2024 has higher properties than 2011 or 2017 an is largely used for aircraft fittings. It is widely used for all types of threaded fasteners because of its relatively higher shear strength.
