The T6 temper is usually achieved by homogenizing the cast 7075 at 450 °C for several hours, quenching, and then aging at 120 °C for 24 hours. This yields the peak strength of the 7075 alloys. The strength is derived mainly from finely dispersed eta and eta' precipitates both within grains and along grain boundaries.

7075 super-hard alloy is the most representative one of 7000 series, is usually used as welding or aircraft materials. 7075 aluminum sheet is used for the manufacturing of high-strength aircraft structures and other high-stress structural parts with great strength and strong corrosion-resistance, such as lower wing panel, stringers, the frame of the aircraft.
