Aluminum 5052 vs 5086
Aluminum · grade comparison
Aluminum 5052 and 5086 are both aluminum grades. 5086 is the stronger of the two: yield strength 207 MPa (30 ksi) against 195 MPa (28.3 ksi) for 5052, about 6% more; tensile strength follows at 290 MPa (42.1 ksi) vs 230 MPa (33.4 ksi). 5086 is harder — 75 HB against 60 HB for 5052 — which matters for wear surfaces and threads. 5052 runs hotter in service (150°C vs 65°C continuous) and 5052 conducts electricity better (35 % IACS vs 31 % IACS). On the shop floor, 5052 forms better (very good vs good) and 5052 sits in a lower cost tier (budget, $) than 5086 (standard, $$).
5052Choose it when the part sees heat, or when cost is the deciding factor.
5086Choose it when strength drives the design, or when surface hardness matters.
5052 vs 5086: 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.
