Aluminum 7072 vs 7095
Aluminum · grade comparison
Aluminum 7072 and 7095 are both aluminum grades. 7095 is the stronger of the two: yield strength 675 MPa (97.9 ksi) against 21 MPa (3.05 ksi) for 7072, about 32 times as much; tensile strength follows at 710 MPa (103 ksi) vs 55 MPa (7.98 ksi). In exchange, 7072 is the more ductile: elongation 32% versus 10% for 7095, and 7095 is harder (190 HB vs 20 HB). 7072 is lighter (2.72 g/cm³ vs 2.86 g/cm³ for 7095) and 7072 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 7095 machines more easily (very good vs poor), 7072 welds better (very good vs poor), and 7072 sits in a lower cost tier (budget, $) than 7095 (high, $$$$).
7072Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
7095Choose it when strength drives the design, or when the part is machined in volume.
7072 vs 7095: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all aluminum grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
