Aluminum 6B02-H112 vs 6B02-T5
Aluminum · 6B02 temper comparison
6B02-H112 and 6B02-T5 are two conditions of the same aluminum grade, 6B02: H112 (strain hardened from hot working only) versus T5 (cooled from hot working and artificially aged). The chemistry is identical, so every difference below comes from the condition. 6B02-T5 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 95 MPa (13.8 ksi) for 6B02-H112, about 100% more; tensile strength follows at 230 MPa (33.4 ksi) vs 165 MPa (23.9 ksi). In exchange, 6B02-H112 is the more ductile: elongation 16% versus 10% for 6B02-T5, and 6B02-T5 is harder (78 HB vs 52 HB). 6B02-H112 runs hotter in service (200°C vs 150°C continuous). On the shop floor, 6B02-T5 machines more easily (54 vs 42 out of 100).
6B02-H112Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
6B02-T5Choose it when strength drives the design, or when the part is machined in volume.
6B02-H112 vs 6B02-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.

6B02-H112 vs 6B02-T5 — frequently asked
Is 6B02-T5 stronger than 6B02-H112?
Yes. 6B02-T5 has a typical yield strength of 190 MPa (27.6 ksi) against 95 MPa (13.8 ksi) for 6B02-H112 — about 100% more. Tensile strength is 230 MPa (33.4 ksi) vs 165 MPa (23.9 ksi).
Which condition does FabDigit quote by default, H112 or T5?
T6 is the default 6B02 condition in the FabDigit quote flow (neither H112 nor T5). 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, 6B02-H112 or 6B02-T5?
6B02-T5, by a small margin. Both rate fair for machinability — 54/100 against 42/100 for 6B02-H112; for welding the order is 6B02-H112 first (very good, 80/100) then 6B02-T5 (very good, 75/100).
