Ag145 vs BAg-13a — frequently asked

Is Ag145 stronger than BAg-13a?

Yes. Ag145 has a typical yield strength of 340 MPa (49.3 ksi) against 210 MPa (30.5 ksi) for BAg-13a — about 62% more. Tensile strength is 450 MPa (65.3 ksi) vs 420 MPa (60.9 ksi).

Which is cheaper, Ag145 or BAg-13a?

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

Which is easier to machine, Ag145 or BAg-13a?

BAg-13a. Its machinability rates good (55/100) against fair (45/100) for Ag145.
