Aluminum Al-Ce-AB vs Al-Ce-T5
Aluminum · Al-Ce temper comparison
Al-Ce-AB and Al-Ce-T5 are two conditions of the same aluminum grade, Al-Ce: AB (as built (as printed)) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. Al-Ce-T5 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 320 MPa (46.4 ksi) for Al-Ce-AB, about 13% more; tensile strength follows at 450 MPa (65.3 ksi) vs 420 MPa (60.9 ksi). In exchange, Al-Ce-AB is the more ductile: elongation 8% versus 6% for Al-Ce-T5, and Al-Ce-T5 is harder (122 HB vs 100 HB). Al-Ce-T5 runs hotter in service (350°C vs 250°C continuous).
Al-Ce-ABChoose it when the part is bent, formed or impact-loaded.
Al-Ce-T5Choose it when strength drives the design, or when the part sees heat.
Al-Ce-AB vs Al-Ce-T5: 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.

Al-Ce-AB vs Al-Ce-T5 — frequently asked
Is Al-Ce-T5 stronger than Al-Ce-AB?
Yes. Al-Ce-T5 has a typical yield strength of 360 MPa (52.2 ksi) against 320 MPa (46.4 ksi) for Al-Ce-AB — about 13% more. Tensile strength is 450 MPa (65.3 ksi) vs 420 MPa (60.9 ksi).
Which condition does FabDigit quote by default, AB or T5?
AB is the default Al-Ce condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, Al-Ce-AB or Al-Ce-T5?
Al-Ce-AB. Its weldability rates very good (75/100) against good (68/100) for Al-Ce-T5.
