Aluminum 1050 vs 1199
Aluminum · grade comparison
Aluminum 1050 and 1199 are both aluminum grades. 1050 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 12 MPa (1.74 ksi) for 1199, about 7.5 times as much; tensile strength follows at 110 MPa (16 ksi) vs 45 MPa (6.53 ksi). In exchange, 1199 is the more ductile: elongation 50% versus 5% for 1050, and 1050 is harder (30 HB vs 13 HB). 1050 is stiffer (69 GPa vs 62 GPa).
1050Choose it when strength drives the design.
1199Choose it when the part is bent, formed or impact-loaded.
1050 vs 1199: 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.

1050 vs 1199 — frequently asked
Is 1050 stronger than 1199?
Yes. 1050 has a typical yield strength of 90 MPa (13.1 ksi) against 12 MPa (1.74 ksi) for 1199 — about 7.5 times as much. Tensile strength is 110 MPa (16 ksi) vs 45 MPa (6.53 ksi).
Which is cheaper, 1050 or 1199?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1050 or 1199?
1050, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for 1199.
