Aluminum 5052 vs 6061

Aluminum · grade comparison

Aluminum 5052 and 6061 are both aluminum grades. 6061 is the stronger of the two: yield strength 276 MPa (40 ksi) against 195 MPa (28.3 ksi) for 5052, about 42% more; tensile strength follows at 310 MPa (45 ksi) vs 230 MPa (33.4 ksi). 6061 is harder — 95 HB against 60 HB for 5052 — which matters for wear surfaces and threads. 6061 runs hotter in service (170°C vs 150°C continuous) and 6061 conducts heat better (167 W/m·K vs 138 W/m·K). On the shop floor, 6061 machines more easily (very good vs fair) and 5052 forms better (very good vs fair).

6061Choose it when strength drives the design, or when surface hardness matters.

5052 vs 6061 — frequently asked

Is 6061 stronger than 5052?

Yes. 6061 has a typical yield strength of 276 MPa (40 ksi) against 195 MPa (28.3 ksi) for 5052 — about 42% more. Tensile strength is 310 MPa (45 ksi) vs 230 MPa (33.4 ksi).

Which is cheaper, 5052 or 6061?

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, 5052 or 6061?

6061. Its machinability rates very good (70/100) against fair (50/100) for 5052; for welding the order is 5052 first (excellent, 90/100) then 6061 (excellent, 85/100).
