Aluminum 6101-H111 vs 6101-T64
Aluminum · 6101 temper comparison
6101-H111 and 6101-T64 are two conditions of the same aluminum grade, 6101: H111 (slightly strain hardened) versus T64 (solution heat treated and under-aged for maximum…). The chemistry is identical, so every difference below comes from the condition. 6101-T64 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 55 MPa (7.98 ksi) for 6101-H111, about 64% more; tensile strength follows at 130 MPa (18.9 ksi) vs 105 MPa (15.2 ksi). 6101-T64 is harder — 40 HB against 28 HB for 6101-H111 — which matters for wear surfaces and threads. On the shop floor, 6101-H111 forms better (excellent vs very good).
6101-T64Choose it when strength drives the design, or when surface hardness matters.
6101-H111 vs 6101-T64: 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.

6101-H111 vs 6101-T64 — frequently asked
Is 6101-T64 stronger than 6101-H111?
Yes. 6101-T64 has a typical yield strength of 90 MPa (13.1 ksi) against 55 MPa (7.98 ksi) for 6101-H111 — about 64% more. Tensile strength is 130 MPa (18.9 ksi) vs 105 MPa (15.2 ksi).
Which condition does FabDigit quote by default, H111 or T64?
T6 is the default 6101 condition in the FabDigit quote flow (neither H111 nor T64). 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, 6101-H111 or 6101-T64?
6101-T64, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for 6101-H111.
