Aluminum 5005 vs 5657

Aluminum · grade comparison

Aluminum 5005 and 5657 are both aluminum grades, both corrosion resistant al. Both yield at about 138 MPa — strength does not separate them. 5657 is the more ductile: elongation 12% versus 8% for 5005. 5005 conducts heat better (200 W/m·K vs 176 W/m·K). On the shop floor, 5005 machines more easily (fair vs poor) and 5005 welds better (excellent vs very good).

5005Choose it when the part is machined in volume, or when it will be welded.

5657Choose it when the part is bent, formed or impact-loaded.

5005 vs 5657 — frequently asked

What is the difference between 5005 and 5657?

Aluminum 5005 and 5657 are both aluminum grades, both corrosion resistant al. Both yield at about 138 MPa — strength does not separate them. 5657 is the more ductile: elongation 12% versus 8% for 5005.

Which is cheaper, 5005 or 5657?

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 5657?

5005. Its machinability rates fair (45/100) against poor (30/100) for 5657; for welding the order is 5005 first (excellent, 88/100) then 5657 (very good, 70/100).
