5050 vs 5154 — frequently asked

Is 5154 stronger than 5050?

Yes. 5154 has a typical yield strength of 205 MPa (29.7 ksi) against 145 MPa (21 ksi) for 5050 — about 41% more. Tensile strength is 270 MPa (39.2 ksi) vs 170 MPa (24.7 ksi).

Which is cheaper, 5050 or 5154?

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

Which is easier to machine, 5050 or 5154?

5154, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 5050.
