Aluminum 7005 vs 7017
Aluminum · grade comparison
Aluminum 7005 and 7017 are both aluminum grades. 7017 is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 295 MPa (42.8 ksi) for 7005, about 32% more; tensile strength follows at 455 MPa (66 ksi) vs 350 MPa (50.8 ksi). 7017 is harder — 138 HB against 94 HB for 7005 — which matters for wear surfaces and threads. 7005 conducts electricity better (40 % IACS vs 32 % IACS).
7017Choose it when strength drives the design, or when surface hardness matters.
7005 vs 7017: 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.

7005 vs 7017 — frequently asked
Is 7017 stronger than 7005?
Yes. 7017 has a typical yield strength of 390 MPa (56.6 ksi) against 295 MPa (42.8 ksi) for 7005 — about 32% more. Tensile strength is 455 MPa (66 ksi) vs 350 MPa (50.8 ksi).
Which is cheaper, 7005 or 7017?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 7005 or 7017?
7017, by a small margin. Both rate good for machinability — 65/100 against 60/100 for 7005; for welding the order is 7005 first (very good, 80/100) then 7017 (very good, 72/100).
