Aluminum 7010 vs 7075
Aluminum · grade comparison
Aluminum 7010 and 7075 are both aluminum grades. 7075 is the stronger of the two: yield strength 503 MPa (73 ksi) against 450 MPa (65.3 ksi) for 7010, about 12% more; tensile strength follows at 572 MPa (83 ksi) vs 515 MPa (74.7 ksi). 7075 is the more ductile: elongation 11% versus 9% for 7010, and 7075 is harder (175 HV vs 155 HV). 7010 conducts heat better (154 W/m·K vs 130 W/m·K).
7075Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
7010 vs 7075: 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.

7010 vs 7075 — frequently asked
Is 7075 stronger than 7010?
Yes. 7075 has a typical yield strength of 503 MPa (73 ksi) against 450 MPa (65.3 ksi) for 7010 — about 12% more. Tensile strength is 572 MPa (83 ksi) vs 515 MPa (74.7 ksi).
Which is cheaper, 7010 or 7075?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 7010 or 7075?
7075, by a small margin. Both rate very good for machinability — 78/100 against 72/100 for 7010.
