7075 T6 Aluminium Alloy Extruded Bar

Last Updated: 2023-04-02

7075 aluminum  (Al-Zn-Mg-Cu) belongs to super-hard aluminum. As a kind of cold finished wrought alloy, it has great strength and hardness. It’s far better than mild steel. This alloy has good mechanical properties and anode reaction. 7075 aluminum as a typical kind of aerospace aluminum alloy material is usually used for high-end fields.

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.
