5005 vs 5050 — frequently asked

Is 5050 stronger than 5005?

Yes. 5050 has a typical tensile strength of 170 MPa (24.7 ksi) against 159 MPa (23.1 ksi) for 5005 — about 7% more.

Which is cheaper, 5005 or 5050?

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, 5005 or 5050?

5005, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 5050.
