Aluminum A20X As Printed vs A20X-HIP
Aluminum · A20X temper comparison
A20X As Printed and A20X-HIP are two conditions of the same aluminum grade, A20X: As Printed (as built (as printed)) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. A20X As Printed is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 200 MPa (29 ksi) for A20X-HIP, about 20% more; tensile strength follows at 380 MPa (55.1 ksi) vs 355 MPa (51.5 ksi). In exchange, A20X-HIP is the more ductile: elongation 18% versus 12% for A20X As Printed, and A20X As Printed is harder (95 HB vs 87 HB). A20X-HIP conducts heat better (135 W/m·K vs 105 W/m·K).
A20X As PrintedChoose it when strength drives the design.
A20X-HIPChoose it when the part is bent, formed or impact-loaded.
A20X As Printed vs A20X-HIP: 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.

A20X As Printed vs A20X-HIP — frequently asked
Is A20X As Printed stronger than A20X-HIP?
Yes. A20X As Printed has a typical yield strength of 240 MPa (34.8 ksi) against 200 MPa (29 ksi) for A20X-HIP — about 20% more. Tensile strength is 380 MPa (55.1 ksi) vs 355 MPa (51.5 ksi).
Which condition does FabDigit quote by default, As Printed or HIP?
As Printed is the default A20X 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 is easier to machine, A20X As Printed or A20X-HIP?
A20X-HIP, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for A20X As Printed.
