The 7075 aluminium alloy, also known as aircraft aluminium or aerospace aluminium, was the first high-strength alloy composed of Al-Zn-Mg-Cu that was able to successfully combine the benefits of the inclusion of chromium to develop high stress-corrosion cracking resistance in sheet products. Zinc served as the alloy's dominant alloying element. The percentage of aluminium in the 7075 aluminium alloy is 87.1 to 91.4%, and the percentage of zinc is 5 to 6%. Additionally, it contains between 2.1 and 2.9% of magnesium, 1.2 and 2% of silicon, titanium, chromium, iron, manganese, and other constituent metals, with a maximum of 0.5% of each.

Aluminium 7075 T6 Channels have a lot of inherited qualities. But because of the alloy used to make the channels, the characteristics are inherited. Corrosion resistance, pitting corrosion resistance, crevice corrosion resistance, and other qualities are among those present in the constructed channels. However, the material also has several additional characteristics, including high toughness, strong tensile strength, and stability at high temperatures.

The 7075-T6 aluminium is an alloy of 7075 aluminium that has been given a T6 temper by being subjected to solution heat treatment, homogenising the 7075 casts for a number of hours at 450 °C, quenching, and then artificially ageing it for 24 hours at 120 °C, or roughly the time it takes to meet the standards for property requirements. By following this procedure, the alloy will reach its maximum strength.
