Aluminum 7116-F vs 7116-T5

Aluminum · 7116 temper comparison

7116-F and 7116-T5 are two conditions of the same aluminum grade, 7116: F (as fabricated) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. 7116-T5 is the stronger of the two: yield strength 355 MPa (51.5 ksi) against 200 MPa (29 ksi) for 7116-F, about 78% more; tensile strength follows at 400 MPa (58 ksi) vs 300 MPa (43.5 ksi). In exchange, 7116-F is the more ductile: elongation 16% versus 12% for 7116-T5, and 7116-T5 is harder (120 HB vs 85 HB). 7116-T5 runs hotter in service (120°C vs 100°C continuous). On the shop floor, 7116-T5 machines more easily (good vs fair).
