Aluminum 5005 vs 5154
Aluminum · grade comparison
Aluminum 5005 and 5154 are both aluminum grades, both corrosion resistant al. 5154 is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 138 MPa (20 ksi) for 5005, about 49% more; tensile strength follows at 270 MPa (39.2 ksi) vs 159 MPa (23.1 ksi). 5154 is the more ductile: elongation 15% versus 8% for 5005, and 5154 is harder (67 HB vs 41 HB). 5005 runs hotter in service (120°C vs 65°C continuous) and 5005 conducts heat better (200 W/m·K vs 125 W/m·K).
5005Choose it when the part sees heat.
5154Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
5005 vs 5154: 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.

5005 vs 5154 — frequently asked
Is 5154 stronger than 5005?
Yes. 5154 has a typical yield strength of 205 MPa (29.7 ksi) against 138 MPa (20 ksi) for 5005 — about 49% more. Tensile strength is 270 MPa (39.2 ksi) vs 159 MPa (23.1 ksi).
Which is cheaper, 5005 or 5154?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose 5005 over 5154?
Pick 5005 when the part sees heat. Pick 5154 when strength drives the design, or when the part is bent, formed or impact-loaded.
