Aluminum 7005 vs 7049
Aluminum · grade comparison
Aluminum 7005 and 7049 are both aluminum grades. 7049 is the stronger of the two: yield strength 475 MPa (68.9 ksi) against 295 MPa (42.8 ksi) for 7005, about 61% more; tensile strength follows at 545 MPa (79 ksi) vs 350 MPa (50.8 ksi). 7049 is harder — 135 HB against 94 HB for 7005 — which matters for wear surfaces and threads. 7049 runs hotter in service (150°C vs 120°C continuous). On the shop floor, 7049 machines more easily (very good vs good), 7005 welds better (very good vs poor), and 7005 forms better (fair vs poor).
7005Choose it when it will be welded, or when cost is the deciding factor.
7049Choose it when strength drives the design, or when surface hardness matters.
7005 vs 7049: 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 7049 — frequently asked
Is 7049 stronger than 7005?
Yes. 7049 has a typical yield strength of 475 MPa (68.9 ksi) against 295 MPa (42.8 ksi) for 7005 — about 61% more. Tensile strength is 545 MPa (79 ksi) vs 350 MPa (50.8 ksi).
Which is cheaper, 7005 or 7049?
7005 is the lower-cost material: it sits in the standard tier ($$) while 7049 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 7005 or 7049?
7049. Its machinability rates very good (72/100) against good (60/100) for 7005; for welding the order is 7005 first (very good, 80/100) then 7049 (poor, 15/100).
