Aluminium 7075 Sheet is an aluminum alloy, with zinc as the primary alloying element. 7075 Aluminium Sheet is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability. ASTM B209 7075 Aluminium Sheet has lower resistance to corrosion than many other Al alloys, but has significantly better corrosion resistance than the 2000 alloys. Its relatively high cost limits its use to applications where cheaper alloys are not suitable. Aluminium 7075 Sheets available in many tempers, some of which are 7075-0, 7075-T6, 7075-T651.
