Aluminium alloy 7075 is an aluminium alloy, with zinc as the primary alloying element.
It is strong, with a strength comparable to many steels, and has good fatigue strength
and average machinability, but has less resistance to corrosion than many other Al alloys.
Its relatively high cost limits its use to applications where cheaper alloys are not suitable.
7000 series alloys such as 7075 are often used in transport applications
Due to its high strength, low density, thermal properties, and its ability to be highly
polished, it is also used in mold tool manufacture With their high strength-to-density ratio.
Their strength and light weight is also desirable in other fields like hobby gear, weapon, etc.
