Aluminum 7095-T651 vs 7095-T7351

Aluminum · 7095 temper comparison

7095-T651 and 7095-T7351 are two conditions of the same aluminum grade, 7095: T651 (T6, stress relieved by stretching) versus T7351 (T73, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 7095-T651 is the stronger of the two: yield strength 675 MPa (97.9 ksi) against 570 MPa (82.7 ksi) for 7095-T7351, about 18% more; tensile strength follows at 710 MPa (103 ksi) vs 620 MPa (89.9 ksi). In exchange, 7095-T7351 is the more ductile: elongation 12% versus 10% for 7095-T651, and 7095-T651 is harder (190 HB vs 163 HB). 7095-T7351 runs hotter in service (150°C vs 120°C continuous) and 7095-T7351 conducts heat better (160 W/m·K vs 135 W/m·K).

7095-T651Choose it when strength drives the design.

7095-T7351Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
