Aluminum 356 vs 852.0
Aluminum · grade comparison
Aluminum 356 and 852.0 are both aluminum grades. 356 is the stronger of the two: yield strength 186 MPa (27 ksi) against 152 MPa (22 ksi) for 852.0, about 22% more; tensile strength follows at 262 MPa (38 ksi) vs 221 MPa (32.1 ksi). 356 is harder — 80 HB against 70 HB for 852.0 — which matters for wear surfaces and threads. 356 is lighter (2.67 g/cm³ vs 2.88 g/cm³ for 852.0). On the shop floor, 852.0 machines more easily (excellent vs very good), 356 welds better (very good vs not recommended), and 356 sits in a lower cost tier (budget, $) than 852.0 (premium, $$$).
356Choose it when strength drives the design, or when surface hardness matters.
852.0Choose it when the part is machined in volume.
356 vs 852.0: 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.
