2014 Aluminum T651 is a copper-alloyed aerospace aluminum with solution heat treatment, stress relief, and artificial aging, delivering tensile strength of approximately 70–75 ksi with enhanced fatigue resistance and dimensional stability for structural aircraft components. The T651 temper provides improved crack resistance compared to T4 while maintaining good machinability, making it suitable for forged and machined airframe fittings, wings, and fuselage sections where fatigue and sustained loads are critical.
