Aluminum 2N01-T4 vs 2N01-T652

Aluminum · 2N01 temper comparison

2N01-T4 and 2N01-T652 are two conditions of the same aluminum grade, 2N01: T4 (solution heat treated and naturally aged) versus T652 (T6, stress relieved by compression). The chemistry is identical, so every difference below comes from the condition. 2N01-T652 is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 205 MPa (29.7 ksi) for 2N01-T4, about 41% more; tensile strength follows at 405 MPa (58.7 ksi) vs 350 MPa (50.8 ksi). In exchange, 2N01-T4 is the more ductile: elongation 16% versus 11% for 2N01-T652, and 2N01-T652 is harder (118 HB vs 95 HB). 2N01-T652 runs hotter in service (200°C vs 120°C continuous) and 2N01-T652 conducts heat better (150 W/m·K vs 130 W/m·K).

2N01-T4Choose it when the part is bent, formed or impact-loaded.

2N01-T652Choose it when strength drives the design, or when the part sees heat.

2N01-T4 vs 2N01-T652 — frequently asked

Is 2N01-T652 stronger than 2N01-T4?

Yes. 2N01-T652 has a typical yield strength of 290 MPa (42.1 ksi) against 205 MPa (29.7 ksi) for 2N01-T4 — about 41% more. Tensile strength is 405 MPa (58.7 ksi) vs 350 MPa (50.8 ksi).

Which condition does FabDigit quote by default, T4 or T652?

T6 is the default 2N01 condition in the FabDigit quote flow (neither T4 nor T652). 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, 2N01-T4 or 2N01-T652?

2N01-T652. Its machinability rates very good (74/100) against good (65/100) for 2N01-T4.
