Aluminum Sheet 7075 O Temper Bare has high strength after heat treatment, light weight, good fatigue resistance, excellent corrosion resistance, and average machinability. 7075, one of the strongest aluminum alloys, was specifically designed for aircraft frames and offers strength slightly superior to steel while maintaining the light weight of aluminum. It is typically used in aerospace, high-end automotive, and defense applications.
HEAT TREATMENT IS NECESSARY TO PROVIDE STRENGTH, AS O TEMPER IS EXTREMELY SOFT
