Aluminum 319 vs 332.0
Aluminum · grade comparison
Aluminum 319 and 332.0 are both aluminum grades. 332.0 is the stronger of the two: yield strength 193 MPa (28 ksi) against 124 MPa (18 ksi) for 319, about 56% more; tensile strength follows at 248 MPa (36 ksi) vs 186 MPa (27 ksi). In exchange, 319 is the more ductile: elongation 2% versus 1% for 332.0, and 332.0 is harder (105 HB vs 70 HB). 332.0 runs hotter in service (250°C vs 200°C continuous). On the shop floor, 319 machines more easily (very good vs good), 319 welds better (good vs poor), and 319 sits in a lower cost tier (budget, $) than 332.0 (standard, $$).
319Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
332.0Choose it when strength drives the design, or when the part sees heat.
319 vs 332.0: 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.
