2017A vs 2A10 — frequently asked

Is 2017A stronger than 2A10?

Yes. 2017A has a typical yield strength of 260 MPa (37.7 ksi) against 245 MPa (35.5 ksi) for 2A10 — about 6% more. Tensile strength is 410 MPa (59.5 ksi) vs 390 MPa (56.6 ksi).

Which is cheaper, 2017A or 2A10?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 2017A or 2A10?

2017A, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for 2A10.
