6060 vs 6063 — frequently asked

Is 6063 stronger than 6060?

Yes. 6063 has a typical yield strength of 214 MPa (31 ksi) against 170 MPa (24.7 ksi) for 6060 — about 26% more. Tensile strength is 241 MPa (35 ksi) vs 215 MPa (31.2 ksi).

Which is cheaper, 6060 or 6063?

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.

When should I choose 6060 over 6063?

Pick 6063 when strength drives the design.
