Aluminum 2030 vs 2219
Aluminum · grade comparison
Aluminum 2030 and 2219 are both aluminum grades. 2219 is the stronger of the two: yield strength 393 MPa (57 ksi) against 285 MPa (41.3 ksi) for 2030, about 38% more; tensile strength follows at 476 MPa (69 ksi) vs 400 MPa (58 ksi). In exchange, 2030 is the more ductile: elongation 12% versus 10% for 2219, and 2219 is harder (130 HB vs 100 HB). 2219 runs hotter in service (200°C vs 100°C continuous). On the shop floor, 2030 machines more easily (excellent vs good) and 2219 welds better (excellent vs not recommended).
2030Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
2219Choose it when strength drives the design, or when the part sees heat.
2030 vs 2219: 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 2219 — frequently asked
Is 2219 stronger than 2030?
Yes. 2219 has a typical yield strength of 393 MPa (57 ksi) against 285 MPa (41.3 ksi) for 2030 — about 38% more. Tensile strength is 476 MPa (69 ksi) vs 400 MPa (58 ksi).
Which is cheaper, 2030 or 2219?
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 2219?
2030. Its machinability rates excellent (92/100) against good (68/100) for 2219; for welding the order is 2219 first (excellent, 85/100) then 2030 (not recommended, 12/100).
