Aluminum 6005 vs 6016

Aluminum · grade comparison

Aluminum 6005 and 6016 are both aluminum grades. 6005 is the stronger of the two: yield strength 245 MPa (35.5 ksi) against 115 MPa (16.7 ksi) for 6016, about 113% more; tensile strength follows at 270 MPa (39.2 ksi) vs 225 MPa (32.6 ksi). In exchange, 6016 is the more ductile: elongation 27% versus 11% for 6005, and 6005 is harder (85 HB vs 60 HB). 6005 runs hotter in service (150°C vs 100°C continuous) and 6005 conducts electricity better (49 % IACS vs 43 % IACS).

6005Choose it when strength drives the design, or when the part sees heat.

6016Choose it when the part is bent, formed or impact-loaded.

6005 vs 6016 — frequently asked

Is 6005 stronger than 6016?

Yes. 6005 has a typical yield strength of 245 MPa (35.5 ksi) against 115 MPa (16.7 ksi) for 6016 — about 113% more. Tensile strength is 270 MPa (39.2 ksi) vs 225 MPa (32.6 ksi).

Which is cheaper, 6005 or 6016?

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 welds better, 6005 or 6016?

6005. Its weldability rates very good (80/100) against very good (75/100) for 6016.
