Aluminum ER4010-T5 vs ER4010-T7

Aluminum · ER4010 temper comparison

ER4010-T5 and ER4010-T7 are two conditions of the same aluminum grade, ER4010: T5 (cooled from hot working and artificially aged) versus T7 (solution heat treated and overaged (stabilized)). The chemistry is identical, so every difference below comes from the condition. ER4010-T7 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 140 MPa (20.3 ksi) for ER4010-T5, about 39% more; tensile strength follows at 235 MPa (34.1 ksi) vs 200 MPa (29 ksi). ER4010-T7 is the more ductile: elongation 6% versus 4% for ER4010-T5, and ER4010-T7 is harder (70 HB vs 65 HB). ER4010-T7 runs hotter in service (200°C vs 160°C continuous).

ER4010-T7Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

ER4010-T5 vs ER4010-T7 — frequently asked

Is ER4010-T7 stronger than ER4010-T5?

Yes. ER4010-T7 has a typical yield strength of 195 MPa (28.3 ksi) against 140 MPa (20.3 ksi) for ER4010-T5 — about 39% more. Tensile strength is 235 MPa (34.1 ksi) vs 200 MPa (29 ksi).

Which condition does FabDigit quote by default, T5 or T7?

AW is the default ER4010 condition in the FabDigit quote flow (neither T5 nor T7). 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 ER4010-T5 over ER4010-T7?

Pick ER4010-T7 when strength drives the design, or when the part is bent, formed or impact-loaded.
