Aluminum Scalmalloy HIP+T6 vs Scalmalloy-T6

Aluminum · Scalmalloy temper comparison

Scalmalloy HIP+T6 and Scalmalloy-T6 are two conditions of the same aluminum grade, Scalmalloy: HIP+T6 versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (HIP+T6 versus solution heat treated and artificially aged). Scalmalloy HIP+T6 is the more ductile: elongation 15% versus 13% for Scalmalloy-T6. On the shop floor, Scalmalloy-T6 machines more easily (good vs fair).

Scalmalloy HIP+T6Choose it when the part is bent, formed or impact-loaded.

Scalmalloy-T6Choose it when the part is machined in volume.

Scalmalloy HIP+T6 vs Scalmalloy-T6 — frequently asked

What is the difference between Scalmalloy HIP+T6 and Scalmalloy-T6?

Scalmalloy HIP+T6 and Scalmalloy-T6 are two conditions of the same aluminum grade, Scalmalloy: HIP+T6 versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (HIP+T6 versus solution heat treated and artificially aged).

Which condition does FabDigit quote by default, HIP+T6 or T6?

As Printed is the default Scalmalloy condition in the FabDigit quote flow (neither HIP+T6 nor T6). 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, Scalmalloy HIP+T6 or Scalmalloy-T6?

Scalmalloy-T6. Its machinability rates good (62/100) against fair (50/100) for Scalmalloy HIP+T6.
