Aluminum 6005 vs 6013

Aluminum · grade comparison

Aluminum 6005 and 6013 are both aluminum grades. 6013 is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 245 MPa (35.5 ksi) for 6005, about 49% more; tensile strength follows at 400 MPa (58 ksi) vs 270 MPa (39.2 ksi). 6013 is harder — 128 HB against 85 HB for 6005 — which matters for wear surfaces and threads. 6005 conducts heat better (188 W/m·K vs 150 W/m·K). On the shop floor, 6013 machines more easily (very good vs good) and 6005 welds better (very good vs good).

6005 vs 6013 — frequently asked

Is 6013 stronger than 6005?

Yes. 6013 has a typical yield strength of 365 MPa (52.9 ksi) against 245 MPa (35.5 ksi) for 6005 — about 49% more. Tensile strength is 400 MPa (58 ksi) vs 270 MPa (39.2 ksi).

Which is cheaper, 6005 or 6013?

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

Which is easier to machine, 6005 or 6013?

6013. Its machinability rates very good (78/100) against good (55/100) for 6005; for welding the order is 6005 first (very good, 80/100) then 6013 (good, 60/100).
