Aluminum 6005 vs 6082
Aluminum · grade comparison
Aluminum 6005 and 6082 are both aluminum grades. 6082 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 245 MPa (35.5 ksi) for 6005, about 8% more; tensile strength follows at 310 MPa (45 ksi) vs 270 MPa (39.2 ksi). 6082 is harder — 95 HB against 85 HB for 6005 — which matters for wear surfaces and threads. 6005 conducts electricity better (49 % IACS vs 41 % IACS).
6082Choose it when strength drives the design, or when surface hardness matters.
6005 vs 6082: 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.

6005 vs 6082 — frequently asked
Is 6082 stronger than 6005?
Yes. 6082 has a typical yield strength of 265 MPa (38.4 ksi) against 245 MPa (35.5 ksi) for 6005 — about 8% more. Tensile strength is 310 MPa (45 ksi) vs 270 MPa (39.2 ksi).
Which is cheaper, 6005 or 6082?
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, 6005 or 6082?
6082, by a small margin. Both rate good for machinability — 62/100 against 55/100 for 6005; for welding the order is 6005 first (very good, 80/100) then 6082 (very good, 75/100).
