Aluminum ADC14-T5 vs ADC14-T6

Aluminum · ADC14 temper comparison

ADC14-T5 and ADC14-T6 are two conditions of the same aluminum grade, ADC14: T5 (cooled from hot working and artificially aged) versus T6 (solution heat treated and artificially aged). The chemistry is identical, so every difference below comes from the condition. ADC14-T6 is the stronger of the two: yield strength 305 MPa (44.2 ksi) against 265 MPa (38.4 ksi) for ADC14-T5, about 15% more; tensile strength follows at 315 MPa (45.7 ksi) vs 295 MPa (42.8 ksi). ADC14-T6 is harder — 145 HB against 125 HB for ADC14-T5 — which matters for wear surfaces and threads.

ADC14-T6Choose it when strength drives the design, or when surface hardness matters.

ADC14-T5 vs ADC14-T6 — frequently asked

Is ADC14-T6 stronger than ADC14-T5?

Yes. ADC14-T6 has a typical yield strength of 305 MPa (44.2 ksi) against 265 MPa (38.4 ksi) for ADC14-T5 — about 15% more. Tensile strength is 315 MPa (45.7 ksi) vs 295 MPa (42.8 ksi).

Which condition does FabDigit quote by default, T5 or T6?

F is the default ADC14 condition in the FabDigit quote flow (neither T5 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.

When should I choose ADC14-T5 over ADC14-T6?

Pick ADC14-T6 when strength drives the design, or when surface hardness matters.
