Aluminum 1199 vs 1200
Aluminum · grade comparison
Aluminum 1199 and 1200 are both aluminum grades. 1200 is the stronger of the two: yield strength 105 MPa (15.2 ksi) against 12 MPa (1.74 ksi) for 1199, about 8.8 times as much; tensile strength follows at 120 MPa (17.4 ksi) vs 45 MPa (6.53 ksi). In exchange, 1199 is the more ductile: elongation 50% versus 9% for 1200, and 1200 is harder (32 HB vs 13 HB). 1200 is stiffer (69 GPa vs 62 GPa) and 1199 conducts electricity better (64.5 % IACS vs 57 % IACS). On the shop floor, 1200 machines more easily (fair vs poor).
1199Choose it when the part is bent, formed or impact-loaded.
1200Choose it when strength drives the design, or when the part is machined in volume.
1199 vs 1200: 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.

1199 vs 1200 — frequently asked
Is 1200 stronger than 1199?
Yes. 1200 has a typical yield strength of 105 MPa (15.2 ksi) against 12 MPa (1.74 ksi) for 1199 — about 8.8 times as much. Tensile strength is 120 MPa (17.4 ksi) vs 45 MPa (6.53 ksi).
Which is cheaper, 1199 or 1200?
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, 1199 or 1200?
1200. Its machinability rates fair (35/100) against poor (25/100) for 1199.
