Aluminum 7093-F vs 7093-T651

Aluminum · 7093 temper comparison

7093-F and 7093-T651 are two conditions of the same aluminum grade, 7093: F (as fabricated) versus T651 (T6, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 7093-T651 is the stronger of the two: yield strength 635 MPa (92.1 ksi) against 290 MPa (42.1 ksi) for 7093-F, about 119% more; tensile strength follows at 690 MPa (100 ksi) vs 400 MPa (58 ksi). In exchange, 7093-F is the more ductile: elongation 12% versus 10% for 7093-T651, and 7093-T651 is harder (178 HB vs 110 HB). 7093-F runs hotter in service (150°C vs 120°C continuous) and 7093-F conducts heat better (158 W/m·K vs 140 W/m·K). On the shop floor, 7093-T651 machines more easily (very good vs good).

7093-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

7093-T651Choose it when strength drives the design, or when the part is machined in volume.

7093-F vs 7093-T651 — frequently asked

Is 7093-T651 stronger than 7093-F?

Yes. 7093-T651 has a typical yield strength of 635 MPa (92.1 ksi) against 290 MPa (42.1 ksi) for 7093-F — about 119% more. Tensile strength is 690 MPa (100 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, F or T651?

T6 is the default 7093 condition in the FabDigit quote flow (neither F nor T651). 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, 7093-F or 7093-T651?

7093-T651. Its machinability rates very good (70/100) against good (55/100) for 7093-F.
