Aluminum 2030 vs 2A14
Aluminum · grade comparison
Aluminum 2030 and 2A14 are both aluminum grades. 2A14 is the stronger of the two: yield strength 400 MPa (58 ksi) against 285 MPa (41.3 ksi) for 2030, about 40% more; tensile strength follows at 480 MPa (69.6 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 10% for 2A14, and 2A14 is harder (135 HB vs 100 HB). 2A14 runs hotter in service (150°C vs 100°C continuous) and 2A14 conducts heat better (155 W/m·K vs 134 W/m·K). On the shop floor, 2030 machines more easily (excellent vs very good) and 2A14 welds better (poor vs not recommended).
2030Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
2A14Choose it when strength drives the design, or when the part sees heat.
2030 vs 2A14: 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.

2030 vs 2A14 — frequently asked
Is 2A14 stronger than 2030?
Yes. 2A14 has a typical yield strength of 400 MPa (58 ksi) against 285 MPa (41.3 ksi) for 2030 — about 40% more. Tensile strength is 480 MPa (69.6 ksi) vs 400 MPa (58 ksi).
Which is cheaper, 2030 or 2A14?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 2030 or 2A14?
2030. Its machinability rates excellent (92/100) against very good (70/100) for 2A14; for welding the order is 2A14 first (poor, 25/100) then 2030 (not recommended, 12/100).
